Abstract: The present invention relates to a culture medium composition for culturing keratinocytes, and more specifically, to a culture medium composition for establishing or culturing keratinocytes, comprising calcium, an epidermal growth factor, and albumin According to the present invention, when keratinocytes are cultured using the culture medium of the present invention, the keratinocytes can be effectively proliferated within a short time, thus making it possible to more quickly obtain a desired number of the cells during the development of a therapeutic agent using the keratinocytes, and the activity of the keratinocytes is improved, and thus the culture medium of the present invention can be useful in the fields of keratinocyte research and the development of therapeutic agents.

Abstract: 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.

Abstract: The present disclosure relates to a composition for inhibiting the extension of a population doubling time of stem cells, comprising a c-Met agonist antibody as an active ingredient, and more particularly, to a medium additive for inhibiting the extension of a population doubling time of stem cells, comprising a c-Met agonist antibody as an active ingredient, a medium composition for culturing stem cells, comprising the medium additive, and a method for inhibiting the extension of a population doubling time.
