Abstract

The invention provides an epidermal stem cell in-vitro culture kit and application thereof. The epidermal stem cell in-vitro culture kit comprises an adherence-promoting culture medium and a transformation-promoting culture medium, the adherence promoting culture medium comprises a stem cell culture medium, a cell culture supplement, fetal calf serum, adherence promoting cell factors and IL-3, and the concentration of IL-3 is 80-120 ng/mL; the transformation-promoting culture medium comprises a stem cell culture medium, a cell culture supplement, a transformation-promoting cell factor, fibronectin and IL-3, and the concentration of IL-3 is 40-80 ng/mL. The invention also provides an epidermal stem cell in-vitro culture method, an epidermal stem cell and an anti-wrinkle injection. The optimized culture medium is matched with the culture method, a large number of epidermal stem cells with high purity can be rapidly obtained, and the epidermal stem cells serving as components of the anti-wrinkle injection are obvious in effect and high in value.

Description

technical field [0001] The invention belongs to the technical field of cell biology, and in particular relates to a kit for culturing epidermal stem cells in vitro and an application thereof. Background technique [0002] Epidermal stem cells (ESCs) are a type of cell population that has the ability to proliferate and can proliferate and differentiate into various functional cells in the epidermis. It is mainly located in the basal layer of the epidermis, belongs to adult stem cells, has a strong ability to divide and proliferate, and can replenish aging and exfoliated keratinocytes. [0003] Epidermal stem cells, as skin tissue-specific stem cells, not only maintain the daily metabolism of the epidermis, but also actively participate in the repair of skin after damage. It is of great significance to explore the proliferation, differentiation and migration of epidermal stem cells. Therefore, obtaining and culturing epidermal stem cells in vitro is the basis of related resea...
