[October 22 AFP] The clone of a hair follicle (already way) is made using a baby’s prepuce, The experiment of the new hair growth method transplanted to a mouse was conducted, and the report of research that the result of the early stage was obtained was released by the U.S. science academy bulletin (Proceedings of the National Academy of Sciences, PNAS) on the 21st.
The hair loss replacement of ? present transplants to another scalp the hair extracted from the scalp, or although use etc. of the medicine to which control and hair restoration of fallen hair are urged are in the mainstream, the hair growth method currently studied newly differs in the method of approach greatly.
“By contrast, a patient’s own cell is used by our method, Professor Angela Chris Ciano (Angela Christiano) (heredity growth study) of the U.S. Columbia University medical center (Columbia University Medical Center) says that he has a possibility of growing up an actually new hair follicle.”
The epoch-making point of research of ? this time is having tried the new method of urging to growth of hair using the papilla-pili cell which plays main roles by formation of a hair follicle.
The papilla-pili cell was not able to breed by two-dimensional cultivation of the plate for an experiment until now.
Then, the research team which obtained the idea to the mouse experiment which is easy to transplant a papilla-pili cell created the clone of man’s papilla-pili cell by the three-dimensional tissue culture.
? organization used the prepuce of the baby who received the prepuce excision way in the center.
Having chosen the baby’s prepuce stimulates man’s dermal papillae, and it calls it the body which works on a patient’s scalp it not only to to work on the hair follicle inside the skin, but to rewrite the fate of a hair follicle completely.
? — when the skin structure and dermal papillae of the newly grown-up human being were transplanted to the mouse, hair growth was carried out by five animals among seven animals.
Hair suited the donor’s gene and it maintained it for at least six weeks.
In ? team, this technology is further fully studied, and if it reaches to the stage where a clinical test can be done, it is expected to the medical treatment of the patients of a burn who need both the man who worries about the early stage of the woman of alopecia, the thin hair by aging, or depilation, the skin, and a hair follicle that an effect is demonstrated.
Professor Colin ジャホダ (Colin Jahoda) (stem cell study) of the coauthor of ? paper and the English Durham university (Durham University) regarded this discovery as “one important step”, and he showed expectation to that a clinical test is done soon.
It says that there is many “problems from an esthetic viewpoint” which ? said person has to solve to AFP from now on [ of what the proof of ultimate principles carried out ], and is saying, “Although whether it grows in woolen growth, the color of hair, and the right direction will just ask for such a thing, people’s present stage is not enough as it.”
