Problems solved by technology

However, this method also has problems. Due to the low efficiency of sweat gland cell separation, purification and subculture, it is difficult to obtain a large amount of culture supernatant; and the composition of the culture supernatant is not clear, and its specific mechanism of action is also unclear; The sweat gland cells of

Abstract

The invention discloses an eccrine sweat gland cell induction medium and an application thereof. The eccrine sweat gland cell induction medium comprises a DMEM / F12 cell medium, a keratinocyt medium, fetal calf serum, an epidermal growth factor, triiodothyronine, hydrocortisone, insulin-transferrin-sodium selenite, L-glutamine, penicillin, streptomycin, a hepatocyte growth factor and a bone morphogenetic protein 4. The eccrine sweat gland cell induction medium disclosed by the invention can be used for successfully inducing stem cells to be directionally differentiated to eccrine sweat gland-like cells so as to provide sufficient eccrine sweat gland cells for treating extensive burn patients, so that the living quality of the patients is greatly improved. The medium further provides a theoretical basis for researching differentiated development of the sweat gland, so that the medium has a potential clinical application prospect.

Description

technical field [0001] The invention relates to a sweat gland cell induction medium and its application in inducing stem cells to differentiate into sweat gland-like cells, belonging to the technical field of sweat gland cell culture. Background technique [0002] The annual incidence of burns in my country is about 1.5% to 2%, that is, about 10 million people suffer from different degrees of burns every year, and nearly 10,000 people suffer from severe burns, and about 10% of the patients cannot save their lives due to lack of skin sources. The rescued patients with extensive burns lost their normal skin function for life due to non-functional scar tissue replacing the skin, which seriously affected the quality of life of the patients. The treatment of severe burns on large areas of skin is a medical and social problem to be solved urgently. [0003] The skin is the largest organ in the human body and has functions such as protecting the body, perspiration, and sensing hea...
