Definitions
- the invention of this application relates to a hair growth method by transplanting hair papilla cells, and a transplant material used in this method.
- the hair follicle tissue that creates hair is formed by the interaction of a special mesenchyme called the papilla with the epidermis. It is thought that the dermal papilla is deeply involved in the progression of the hair cycle, which is the cycle of hair elongation and arrest. Male-type hair loss (symptoms) develops when the hair cycle is modulated by various causes such as male lemon concentration and deterioration of blood circulation. In the later stage of androgenetic alopecia, the treatment of hair follicle tissue is required to increase the number of hair follicle tissues through cell transplantation, because the effects of hair growth treatments and the like are low and the density of the dermal papilla is low. .
- the conventional treatment technique is to reduce the area of the alopecia site by removing the skin at the site of alopecia and then implanting the scalp tissue itself with healthy hair on the head or temporal region at the alopecia site.
- Non-Patent Document 1 a method of surgically separating hair follicles from a healthy scalp and then transplanting the hair follicles to the site of alopecia has been reported and has improved the therapeutic effect.
- any of these methods can reduce the area of the alopecia site, but the number of hair follicles or the total number of hairs must be reduced to the same level as the current situation.
- Non-patent Document 3 Non-patent Document 3
- hair follicles with healthy traits cover alopecia-onset sites and are effective as the only radical treatment method that can provide hair that is difficult to lose hair even when exposed to various alopecia-onset factors.
- a method has been adopted in which a polymer polymer processed so as to have biocompatibility is inserted into the skin and made compatible with the dermis tissue and subcutaneous tissue.
- this method has resulted in considerable immune rejection and infectious disease, which has already been banned in the United States.
- the patient's own cells can be separated from extremely small tissues, cultured, proliferated, and used as a material to construct hair follicles, thereby increasing the number of hair follicles for transplantation
- Patent Document 1 discloses a method in which hair papilla cells isolated from a patient's own scalp are cultured and propagated, and the cultured hair papilla cells are transplanted into a patient.
- the efficiency of hair growth is extremely low even when transplanted into the skin with cultured dermal papilla cells, and even if hair grows, the condition of the hair is fragile, and it is difficult to say that natural hair is regenerated.
- tissue engineering techniques are used based on embryological findings. The law must be applied. Embryologically, as described above, hair follicles are formed by the interaction between epidermal cells and dermal papilla cells.
- Non-Patent Document 5 a method of hair follicle formation using a combination of human hair papilla and animal hair follicle has already been reported (Non-Patent Document 5), and it is known that it can be applied to the treatment of alopecia in humans. .
- the artificial dermal papilla which consists of dermal papilla and cultured dermal papilla cells, reconstructs a new hair follicle in the skin by incising the skin with sharp forceps and then manually transplanting it into the dermis and epidermal space It has been reported that this is possible (Non-Patent Document 6).
- a method of transplantation into the skin using an injector has been attempted, and it has been reported that hair follicle structures and hair are induced in the hair papilla or the site of hair papilla cell transplantation with limited results ( Patent Document 1).
- hair follicle formation which is controlled by the interaction between epidermal cells and dermal papilla cells, must be in close proximity until epidermal and dermal papilla cells can interact.
- transplantation of dermal papilla cells directly under the epidermis, or a mixture of epidermal cells and dermal papilla cells can be considered.
- Transplanting hair papilla cells very close to the epidermis requires sophisticated techniques to control the cell transplant location with extremely high precision.
- the fibers of extracellular matrix mainly composed of collagen constructed by fibroblasts are entangled. When injecting drug transport carriers such as micro-tissues, cells and collagen beads into the skin, they must be suspended in physiological saline, medium, serum, etc.
- hair papilla cells isolated and cultured from rat whiskers can be prepared by adding fibroblast growth factor 2 (FGF2) or primary culture supernatant of rat sole epidermal cells to the culture medium.
- FGF2 fibroblast growth factor 2
- Patent Document 3 As described above, for hair growth by transplantation of hair papilla cells, the hair papilla or cultured hair papilla cells were surely brought close to the epidermal cells, and a larger number of transplants were transplanted with less burden on the recipient. It is necessary to efficiently grow hair from hair papilla cells.
- Non-Patent Document 7 It is also known that the hair growth inducing ability of hair papilla cells is reduced by repeating subculture for about ten generations.
- Patent Document 3 a culture technique for growing hair papilla cells while maintaining the hair follicle inducing ability for a long period of time.
- Patent Document 3 Even in the case of hair papilla cells cultured and expanded by the method of Patent Document 3, hair follicle formation after transplantation is possible, but the hair growth inducing ability is attenuated and lost with the passage. Absent. Therefore, there is also a strong demand for a method of transplanting hair papilla cells grown by long-term subculture with sufficient hair growth inducing ability.
- the dermal sheath is a tissue composed of dermal cells surrounding the outermost layer of the hair follicle.
- the dermal root sheath is continuous with the dermal papilla at the lowest end of the bulb (Fig. 7, arrowhead). Transplantation of the hair follicle from which the dermal papilla and hair matrix have been partially resected into the renal capsule or subcutaneous tissue will result in It is considered that the precursor cells of the hair papilla cells are distributed in the dermal root sheath, because the part is reconstructed and the length of the capillary is observed.
- Non-Patent Document 8 it was reported that hair follicle formation was induced and hair growth occurred.
- Non-Patent Document 9 it has been reported that, as a result of an experiment in which primary cultured dermal root sheath cells were transplanted directly below the hairless skin epidermis of the auricle, hair follicle formation was induced and hair growth occurred.
- dermal root sheath cells are also considered to be a promising transplant material for hair regeneration.

One week after cell transplantation, skin from the transplanted cells had formed. Three weeks after cell transplantation, hair growth was observed at the site where the cultured papillary cells were cultured for 6 passages (Fig. 8-a), but no hair growth was observed for cells at 39 passages (Fig. 9-a). However, observation of HE-stained images of both tissues confirmed hair follicles (Fig. 8-b, Fig.
