- Anemia is one of erythrocytopenia, defined as a physiological response in which the oxygen supply to tissue cells decreases due to a decrease in the number of hemoglobin, a decrease in the amount of hemoglobin in the blood, and a decrease in the oxygen binding capacity of the hemoglobin molecule.
- There are more than 400 types of anemia and it is caused by various causes such as iron deficiency, nutrient deficiency such as folic acid, hemolytic, inflammatory nitrification, and decreased bone marrow function. It is reported. Since anemia observed at a high rate is accompanied by various pathological phenomena, various treatments for different causes have been tried to treat this.
- CD34 + hematopoietic stem cells were isolated purely, cultured in vitro, and then amplified, followed by induction of differentiation into erythrocytes using erythropoietin. However, since these processes require a lot of cytokines, there are many economic problems.
- EC-18 is a kind of monoacetyletyldiglyceride, it was isolated from antler. EC-18 significantly increased the survival rate of animals in sepsis animal models using cecal-ligation-puncture, and showed no toxicity in GLP (Good Laboratory Practice) toxicity studies.

- Red blood cell differentiation or proliferation promoting composition of the present invention comprises a monoacetyldiacylglycerol compound represented by the formula (1).
- a monoacetyldiacylglycerol compound represented by the formula (1).
- the term “monoacetyldiacylglycerol compound” refers to a derivative of glycerol having one acetyl group and two acyl groups, and is also referred to as monoacetyldiacylglycerol (MADG).
- R1 and R2 may each be a fatty acid group having 14 to 20 carbon atoms, preferably palmitoyl, oleoyl, linoleoyl, Linolenoyl, stearoyl, myristoyl, or arachidonoyl, and the like may be, but are not limited thereto.

As used herein, the term “erythrocyte progenitor cell” refers to all cells included in the erythrocyte formation process except for the mature red blood cells.
- hematopoietic stem cells capable of differentiation into various hematopoietic cells are present, and some of the hematopoietic stem cells are differentiated into erythroid progenitor cells whose direction of differentiation into the erythroid system is determined.
- the most primitive identified as erythrocyte progenitors is BFU-E (burst forming unit-erythroid) and slightly differentiated CFU-E (colony forming unit-erythroid). .
- the erythroid progenitor cells are differentiated by dividing into proerythroblast, basophilic erythroblast, polychromatophilic erythroblast, or orthochromatic erythroblast, The polychromatic erythrocytes then mature into red blood cells by denuclearization.
- the direction of differentiation into the erythroid system is completely determined, and there is no case of differentiation into a hemocytometer other than erythrocytes. For this reason, when the number of BFU-E and CFU-E increases, red blood cell hematopoiesis is promoted.
- Erythrocyte hematopoiesis is mainly maintained by Erythropoetin (EPO), which is a hematopoietic factor. Erythropoietin is produced mainly in the kidney and circulates in the blood, and acts on CFU-E in the bone marrow to stimulate red blood cell hematopoiesis by stimulating proliferation and differentiation. If EPO is not produced at normal levels and is lacking, CFU-E may be reduced, leading to a decrease in red blood cell hematopoiesis, resulting in erythrocytopenia or anemia.
- EPO Erythropoetin
- red blood cells is a cell that occupies the largest number of blood cells, and has a flat disk shape of red color, and serves to supply oxygen to tissues of the body and remove carbon dioxide through blood vessels. It is also called red blood cells. Red blood cells are cells specialized for oxygen transport. Unlike most other cells that make up our bodies, red blood cells do not contain nuclei and contain hemoglobin for oxygen transport. One ml of blood in a normal adult man contains between four and six billion red blood cells. Erythrocytes are produced by the differentiation of erythrocyte progenitor cells in the bone marrow, producing 2.4 million new erythrocytes per second.
- Erythrocytes normally cycle through the body for 100 to 120 days, and at the end of their lifespan, red blood cells are destroyed by macrophages in organs of the reticulum (the reticulum), including the spleen, liver and bone marrow.
- the term “differentiation” refers to a phenomenon in which the structure or function of each other during cell division or proliferation and growth, that is, the shape or function of the cells, tissues, etc. of the organism to perform the task given to each It means to change.
