摘要： The present invention relates to a culture medium composition obtained by further adding at least one selected from the group consisting of rotenone and albumin to a serum-free medium prepared through a CAMPs technology. It has been ascertained that the proliferation of dermal papilla cells and maintenance of characteristics thereof during culturing can be improved by regulating the concentration of rotenone and albumin, and since the culture medium composition is a serum-free chemical medium comprising no serum, there is no risk of side effects, which can be caused by using a conventional serum medium, during use on the human body.
The culture medium composition of the present invention obtained by further adding at least one selected from the group consisting of rotenone and albumin to a serum-free medium, or dermal papilla cells cultured through the composition can be effectively used in the development of therapeutic agents for hair loss prevention and hair growth promotion.

摘要： Hair follicle stem cells are isolated from mammals by isolating nestin-expressing cells. These hair follicle stem cells are a source of adult stem cells for autologous or heterologous stem cell therapy. The stem cells can be systemically implanted into the mammal or directly implanted into the organ. In addition, the stem cells may be further differentiated in vitro and then implanted systemically or directly into the mammal.

摘要： The present invention is directed to methods for readily propagating somatic hair follicle stem cells or melanocyte stem cells. The methods comprise enhancing guanine nucleotide (GNP) biosynthesis, thereby expanding guanine nucleotide pools. This in turn conditionally suppresses asymmetric cell kinetics in the explanted cells. The methods of the invention include pharmacological methods and genetic methods. For example, the resulting cultured somatic hair follicle stem cells can be used for a variety of applications including cell replacement therapies such as hair transplants, gene therapies, and tissue engineering applications, such as the generation of artificial skin and skin regeneration strategies including skin grafts.

摘要： The present invention relates to a method for isolating hair follicle stem cells and a composition for inducing hair growth. More specifically, relates to a method for isolating hair follicle stem cells showing a positive immunological response to CD34, by chemically degrading hair follicle-containing scalp tissue and then culturing the degraded tissue in a serum-containing medium and a serum-free medium, as well as a composition for inducing hair growth, which contains, as an active ingredient, CD34-positive hair follicle stem cells isolated by the method. The hair follicle-derived stem cells, which are obtained according to the disclosed method, are classified as autologous adult stem cells, have self-renewal capability, the ability to differentiate into adult hair follicle cells and the ability to induce hair growth, and can be used as a novel cell therapeutic agent against hair loss. In addition, the present invention relates to a method for culturing hair follicle cells, which has high yield compared to that of the prior art, as well as a method for identifying hair follicle stem cells.
