Abstract
The present invention relates to a composition for promoting proliferation of bone marrow derived stem cells using an angelicae gigantis radix extract, and more particularly, to a composition which administers a granulocyte colony-stimulating factor into an object, and administers the angelicae gigantis radix extract to the object to promote the proliferation of the bone marrow derived stem cells. The composition of the present invention solves side effects such as splenomegaly which were caused by a method of administering only the G-CSF for proliferation and differentiation of the stem cells, thereby significantly mitigating the side effects through co-administration of the angelicae gigantis radix extract, and further promoting the proliferation and the differentiation of the stem cells.
Description
- The present invention provides a composition containing an angelicae gigantis radix extract for promoting proliferation of bone marrow derived stem cells.
- “Stem cell” is a generic term for undifferentiated cells that can differentiate into various cells forming biological tissues and obtained from tissue of embryos, fetuses, and adults. Among various stem cells, adult stem cells are cells derived from bone marrow, and are multifunctional stem cells which can be differentiated into any cell forming an organ and blood of a human body.
- Among these, bone marrow derived stem cells are considered as an ultimate means of treating diseases such as hematologic cancers, lymphoma, and bone marrow failure. Transplantation of bone marrow derived stem cells is currently being performed for various purposes, and particularly when organ transplantation is difficult in critical kidney and liver patients, a method of promoting regeneration of the liver and kidneys is being attempted by transplanting autologous bone marrow derived stem cells.
- After the autologous bone marrow derived stem cells are transplanted, to promote differentiation and division of the stem cells, a recombinant human granulocyte colony-stimulating factor (hG-CSF) is administered in full dose. However, in about 5-30% of patients, proliferation or mobilization toward blood does not occur in the stem cells, and various side effects such as myocardial infarction, cerebral infarction, fever, ostalgia, splenomegaly, splenic rupture, etc. are known to be caused by the administration of hG-CSF (Masood et al., 2008; Fox et al., 2009). Particularly, the use of hG-CSF is being limited due to its high cost. Consequently, a new alternative means which is capable of promoting an effect of hG-CSF in proliferating the bone marrow derived stem cells, or mitigating the side effects of hG-CSF is required.
- Angelicae gigantis radix is a dried substance of roots of Angelica gigas NAKAI, A. sinensis DIELS, and A. acutiloba KITAG, which are perennial herbs belonging to the family Umbelliferae, along with other congeneric, closely-related plants, and is known to have effects of replenishing blood to cure lack of blood supply, reducing menstrual cramps, and moisturizing the intestine to relieve constipation. The roots perform a sedative action, an antispasmodic action, a hypotensive action, etc., and aqueous solutions of essential oils of the roots perform an analgesic action and an anti-inflammatory action when used to treat arthritis. In the field of oriental medicine, the roots are mostly used in anemia, gynecopathy, and postpartum recovery, and are also used for serious coughing, boils, etc. Meanwhile, Korean Unexamined Patent Application Publication No. 2012-0092754 has disclosed content related to promoting differentiation of stem cells using Chrysanthemum zawadskii, which is a medicinal herb, but there has been no example of promoting differentiation of “bone marrow derived” stem cells using an angelicae gigantis radix extract.

- A period of administering the angelicae gigantis radix extract may begin within thirty minutes after administration of the G-CSF, preferably within fifteen minutes, and most preferably within five minutes, but the administration period is not limited thereto.
- The G-CSF used in the present invention is the recombinant hG-CSF, but is not limited thereto.
- The G-CSF and the angelicae gigantis radix extract may be administered parenterally, orally, locoregionally, or percutaneously. Although it is preferable that the angelicae gigantis radix extract be administered orally, the administration method may be properly selected by those of ordinary skill in the art in accordance with a condition and body weight of a patient, an extent of a disease, a period, etc.
- In the present invention, an “individual” refers to an object which requires a treatment of a disease, and more specifically, refers to mammals such as humans or non-human primates, mice, rats, dogs, cats, horses, cattle, etc.

Administration Method
- Administration of hG-CSF and Candidate Drugs
- In accordance with previous methods (Verma et al., 1997; Levesque et al., 2003), 250 μg/kg of the hG-CSF (Life Technologies, Carlsbad, Calif., USA) was subcutaneously administered once per day for six consecutive days to promote proliferation of leukocytes and mobilization of bone marrow derived stem cells, and within five minutes of administering the hG-CSF, 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were orally administered once per day for the six consecutive days. All five types of natural product derived extracts were dissolved in sterilized distilled water and forcibly orally administered in a volume of 10 mL per kg of animal body weight using a 1 mL syringe to which a metallic zonde was attached, and the hG-CSF was dissolved in normal saline and subcutaneously administered in a volume of 10 ml/kg in dorsal subcutaneous portions. Only sterilized distilled water of the same volume was administered in an hG-CSF control group instead of the natural product derived extracts, and normal saline and sterilized distilled water of the same volume were administered at five minute intervals in a normal media control group instead of the hG-CSF and the natural product derived extracts. The administration amount of the natural product derived extracts used in the present experiment, i.e., 200 mg/kg, was selected based on results of individual animal experiments.
- 1-4. Observations
- Together with changes in body weights and spleen weights, and total number of bone marrow nuclear cells and blood leukocytes, numbers of CD34+ and CD45+ cells, which are representative markers of bone marrow derived stem cells, were observed in bone marrow and blood by a method of using the fluorescence activated cell sorter (FACs). In addition, the numbers of CD34+ and CD45+ cells per unit area in tissue samples of spleens and bone marrow were observed using an area histochemical method, and total thicknesses of spleens, amounts and diameters of white pulp, and amounts of red pulp in spleens and nuclear cells in bone marrow per unit area were also evaluated using an automatic image analyzer (iSolution FL ver 9.1, IMT i-solution Inc., Quebec, Canada). To observe clearer changes, a % change between the normal media control group and the hG-CSF control group, and % changes between each of the groups to which natural product derived extracts were administered and the hG-CSF control group were calculated and compared.
- As a result of the observation, changes in weights and weight gains were measured and are illustrated in Table 4 and
FIG. 2 . As can be seen inFIG. 2 , compared with the normal media control group, significant changes in weights and weight gains related to administration of the hG-CSF or the natural product derived candidate substances were not seen in the entire period of the experiment. -

- Amounts of changes in the weights of spleens observed in the present example are illustrated in Table 5 below. Significant (p<0.01) increase in relative weights with respect to spleens and body weights due to noticeable splenomegaly was seen in the hG-CSF control group compared to the normal media control group, and significant (p<0.01) decrease in weights of spleens were seen in the groups to which PMT and angelicae gigantis radix extracts were administered compared to the hG-CSF control group.

FIG. 3 , as a result of checking the sizes of the spleens with the naked eye, it was confirmed that the sizes of spleens of the groups to which PMT and angelicae gigantis radix extracts were administered decreased compared to the normal media control group. - Meanwhile, significant (p<0.05) increase in absolute and relative weights of spleens was seen in the cervi cornu parvum administration group compared to the hG-CSF control group, and significant changes in the weights of the spleens were not seen in the groups to which SCGBT and astragali radix extracts were administered compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 99.55% change in the absolute weights of spleens compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −21.08, 5.61, −5.38, 13.65, and −17.51%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 99.81% change in the relative weights of spleens compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −20.85, 4.57, −6.13, 13.46, and −19.46%, respectively, compared to the hG-CSF control group.
- From the above results, it was confirmed that co-administration of the G-CSF and the angelicae gigantis radix extract can mitigate splenomegaly, which is a side effect of the G-CSF.
- In the present experiment, numerical changes in blood leukocytes and bone marrow nuclear cells were observed and the results thereof are illustrated in Table 6.

- The hG-CSF control group exhibited a 955.34% change in the total number of blood leukocytes compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 3.93, −10.67, −1.69, 36.70, and 6.93%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 872.19% change in the total number of bone marrow nuclear cells compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −3.73, −3.01, −5.68, 28.87, and −2.86%, respectively, compared to the hG-CSF control group.
- Consequently, it was confirmed that the total numbers of blood leukocytes and bone marrow nuclear cells were not increased compared to the hG-CSF control group when the angelicae gigantis radix extract was administered, but remained at a similar increasing level.
- Numerical changes in CD34+ and CD45+ cells in blood and bone marrow were observed by a method using the FACs, and the results thereof are illustrated in Table 7.

Numerical Changes in CD34+ Cells in Blood and Bone Marrow
- FACS observation results of CD34+ cells are illustrated in
FIGS. 4 and 5 . When the results are viewed in conjunction with Table 7, significant (p<0.01) numerical increase in CD34+ cells in blood and bone marrow was seen in the hG-CSF control group compared to the normal media control group, and significant (p<0.01) numerical increases in CD34+ cells in blood and bone marrow were seen in the groups to which PMT, cervi cornu parvum, and angelicae gigantis radix extracts were administered even when compared to the hG-CSF control group. Meanwhile, significant numerical increases in CD34+ cells in blood and bone marrow were not seen in the groups to which SCGBT and astragali radix extracts were administered compared to the hG-CSF control group. - The hG-CSF control group exhibited a 238.08% change in the number of CD34+ cells in blood compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 61.89, −17.41, −6.39, 51.65, and 53.85%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 83.14% change in the number of CD34+ cells in bone marrow compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 48.29, 2.64, 6.62, 33.00, and 45.80%, respectively, compared to the hG-CSF control group.
- By the above results, compared with a case only G-CSF is administered, it was confirmed that the numbers of CD34+ cells in the blood and the bone marrow significantly increase when the angelicae gigantis radix extract is co-administered with the G-CSF.
- 5.2. Numerical Changes in CD45+ Cells in Blood and Bone Marrow
- FACs observation results of CD45+ cells are illustrated in
FIGS. 6 and 7 . When the results are viewed in conjunction with Table 7, significant (p<0.01) numerical increase in CD45+ cells in blood and bone marrow was seen in the hG-CSF control group compared to the normal media control group, and significant (p<0.01) numerical increases in CD45+ cells in blood and bone marrow were seen in the groups to which PMT, cervi cornu parvum, and angelicae gigantis radix extracts were administered even when compared to the hG-CSF control group. Meanwhile, significant numerical increases in CD45+ cells in blood and bone marrow were not seen in the groups to which SCGBT and astragali radix extracts were administered compared to the hG-CSF control group. - The hG-CSF control group exhibited a 312.39% change in the number of CD45+ cells in blood compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 44.38, −2.75, 5.45, 32.26, and 42.72%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 87.18% change in the number of CD45+ cells in bone marrow compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 31.35, 3.02, −2.68, 15.47, and 26.58%, respectively, compared to the hG-CSF control group.
- By comparing the above results with a case in which only G-CSF is administered, it was confirmed that the numbers of CD45+ cells in the blood and the bone marrow significantly increase when the angelicae gigantis radix extract is co-administered with the G-CSF.
- Consequently, referring to the results of examples 5.1 and 5.2, it can be confirmed that the co-administration of the angelicae gigantis radix extract significantly increases proliferation of the bone marrow derived stem cells.
- Histopathological changes of spleens and femoral bone marrow were observed in eight groups and values thereof are illustrated in Table 8 below.

Histopathological Change in Spleens
- As can be seen in Table 8 above, the hG-CSF control group showed a feature of splenomegaly caused by significant infiltration of nuclear cells in red pulp of spleens. Although significant (p<0.01) increases in the total thicknesses of the spleens and nuclear cells per unit area of the red pulp were seen compared to the normal media control group, the amount and the diameter of white pulp was observed to be similar with the normal media control group.
-
FIG. 8 is a picture illustrating total thicknesses of the spleens and the numbers of nuclear cells per unit area of the red pulp and the white pulp of the spleens. As can be seen inFIG. 8 , although the groups to which PMT and angelicae gigantis radix extracts were administered showed significant (p<0.01) decreases in the total thicknesses of the spleens and the numbers of nuclear cells per unit area of the red pulp of the spleens compared to the hG-CSF control group, the SCGBT administration group showed a significant (p<0.01) increase in the total thickness of the spleen compared to the hG-CSF control group, and the groups to which the astragali radix and cervi cornu parvum extracts were administered showed no significant histopathological changes in the spleens compared to the hG-CSF control group. - The hG-CSF control group exhibited a 17.47% change in the total thickness of the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −12.02, 10.72, −0.48, 7.81, and −9.75%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 0.69% change in the amount of white pulp in the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −3.42, −4.11, 1.37, 2.05, and 0.00%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 4.17% change in the mean diameter of the white pulp of the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 3.09, 1.34, 0.77, 1.96, and −1.26%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 714.75% change in the number of nuclear cells per unit area of the red pulp of the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −29.76, 6.39, 12.76, −1.55, and −35.21%, respectively, compared to the hG-CSF control group.
- 6.2. Histopathological Change in Femoral Bone Marrow
- As can be seen in Table 8 above, the hG-CSF control group showed significant proliferation of granulocytes. As illustrated in
FIG. 9 , although a significant (p<0.01) increase in nuclear cells per unit area of bone marrow was seen in comparison to the normal media control group, no significant histopathological changes in femoral bone marrow were seen in any of the groups to which natural product derived extracts were administered compared with the hG-CSF control group. - The hG-CSF control group exhibited a 357.02% change in the number of nuclear cells per unit area of the femoral bone marrow compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of −2.75, −5.02, −9.79, 7.40, and −9.68%, respectively, compared to the hG-CSF control group.
- From examples 6.1 and 6.2, it can be confirmed that the co-administration of the angelicae gigantis radix can prevent the side effects such as splenomegaly caused by administration of only the G-CSF, and increase leukocytes at the same time.
- Numbers of CD34 and CD45 immunoreactive cells in spleens and bone marrow with respect to seven groups are illustrated in Table 9 below.

Numerical Changes in CD34 Immunoreactive Cells in Spleens and Bone Marrow
- As can be seen in Table 9 and
FIG. 9 , the hG-CSF control group showed a significant (p<0.01) numerical increase in CD34 immunoreactive cells in spleens and bone marrow compared to the normal media control group, and the groups to which PMT and angelicae gigantis radix extracts were administered showed significant (p<0.01) numerical increases in CD34 immunoreactive cells in the spleens and the bone marrow even when compared to the hG-CSF control group. Meanwhile, no significant numerical changes in CD34 immunoreactive cells per unit area of the spleens and the bone marrow were seen in the groups to which SCGBT, cervi cornu parvum, and astragali radix extracts were administered compared to the hG-CSF control group. - The hG-CSF control group exhibited a 713.41% change in the number of CD34 immunoreactive cells in the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 30.88, 3.22, 10.04, −5.92, and 20.39%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 305.26% change in the number of CD34 immunoreactive cells in the bone marrow compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 60.61, −10.61, 6.93, —8.87, and 75.32%, respectively, compared to the hG-CSF control group.
- 7.2. Numerical Changes in CD45 Immunoreactive Cells in Spleens and Bone Marrow
- As can be seen in Table 9 and
FIG. 10 , the hG-CSF control group showed a significant (p<0.01) numerical increase in CD45 immunoreactive cells in spleens and bone marrow compared to the normal media control group, and the groups to which PMT and angelicae gigantis radix extracts were administered showed significant (p<0.01) numerical increases in CD45 immunoreactive cells in the spleens and the bone marrow even when compared to the hG-CSF control group. Meanwhile, although a significant (p<0.01) numerical increase in the CD45 immunoreactive cells in the spleen was seen in the cervi cornu parvum extract administration group compared to the hG-CSF control group, the CD45 immunoreactive cells in the bone marrow were observed to be similar with the hG-CSF control group, and no significant numerical changes in CD45 immunoreactive cells per unit area of the spleens and the bone marrow were seen in the groups to which SCGBT and astragali radix extracts were administered compared to the hG-CSF control group. - The hG-CSF control group exhibited a 575.95% change in the number of CD45 immunoreactive cells in the spleen compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 33.51, −0.99, 7.91, 57.26, and 52.36%, respectively, compared to the hG-CSF control group.
- The hG-CSF control group exhibited a 808.94% change in the number of CD45 immunoreactive cells in the bone marrow compared to the normal media control group, and the groups to which 200 mg/kg of PMT, SCGBT, astragali radix, cervi cornu parvum, and angelicae gigantis radix extracts were administered exhibited changes of 50.61, 7.56, 12.14, 5.84, and 64.94%, respectively, compared to the hG-CSF control group.
- From the above results, it was confirmed that the co-administration of the angelicae gigantis radix extract can significantly increase the number of immunoreactive cells compared to the case in which only the G-CSF is administered.
- To summarize the results of examples 2 to 7, a significant increase in the weight of spleens, an increase in total numbers of nuclear cells in blood and bone marrow, and numerical increases in CD34+ and CD45+ cells in the blood and the bone marrow were seen, increases in total thicknesses of spleens and numerical increases in nuclear cells per unit area of red pulp and femoral bone marrow were seen in a histopathological aspect, and numerical increases in CD34 and CD45 immunoreactive cells in the spleens and the bone marrow were seen in an immunohistochemical aspect.
- Consequently, by the oral co-administration of the angelicae gigantis radix extract within five minutes of administration of the hG-CSF, proliferation and mobilization of bone marrow derived stem cells by the hG-CSF were significantly (p<0.01) increased, an increase in the weights of spleens and features of splenomegaly due to proliferation of nuclear cells in red pulp were significantly (p<0.01) suppressed, and proliferation of overall granulocytes was not affected.
- Meanwhile, although significant proliferation and mobilization of the bone marrow derived stem cells were also seen in the cervi cornu parvum extract administration group, the features of splenomegaly actually worsened. Administering the SCGBT and the astragali radix extracts was observed not to affect granulocytes of hG-CSF and proliferation and mobilization of the bone marrow derived stem cells, and was also observed not to affect side effects such as splenomegaly.
- Consequently, the angelicae gigantis radix extract is expected to provide a new method of fusing western and oriental medicine which is very useful in enhancing an effect of hG-CSF in mobilizing the bone marrow derived stem cells and mitigating side effects such as splenomegaly.
- The above description of the present invention is for illustrative purposes, and those of ordinary skill in the art will be able to understand that the examples of the present invention may be easily modified in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, the above-described examples should be construed as being illustrative in every aspect, not limitative.
