The invention relates to the field of cytobiology, and particularly relates to a sweat gland differential induction medium and applications thereof. The sweat gland differential induction medium is prepared by adding the following components into a low-sugar DMEM medium: based on the volume of the low-sugar DMEM medium, 8-15% by volume of fetal calf serum, 0.3-0.5mu g / ml of semi-hydrocortisone succinate, 10-100ng / ml of rh-KGF, 1-3nmol / ml of triiodothyronine, 10-100ng / ml of rh-EGF, and 0.05-0.2ml / ml of an insulin-transferrin-sodium selenite solution. The sweat gland differential induction medium is constructed by taking a recombinant human keratinocyte growth factor as a key regulation factor, constructing the finished product of the sweat gland differential induction medium, inducing the differentiation of human umbilical cord mesenchymal stem cells to sweat gland sample cells. By using the medium disclosed by the invention, the result is stable and reliable, and the sweat gland differential induction medium can be widely used for related studies and clinical application of differential induction of various MSCs to the sweat gland cells.

The invention provides a method for improving hair biology, e.g., hair growth. The method comprises administering to a subject a monoamine oxidase inhibitor and a vasodilator, a zinc salt of a carboxylic acid, a xanthine compound, pyrithione or a salt thereof, saponin, tritapene, crataegolic acid, celastrol, asiatic acid, an inhibitor of 5-alpha-reductase, 1,4-methyl-4-azasteroid, an androgen receptor antagonist, azelaic acid or a derivate thereof, cyclosporin, triiodothyronine, diazoxide, retinoic acid, a prostaglandin analog, aminexil, carnitine tartrate, apigenin, procapil, or adenosine, in an amount effective to achieve a desired effect. The invention further provides a method of reducing or delaying the appearance of an age-related skin imperfection. The method comprises administering to the subject a composition comprising an MAO inhibitor. A kit for improving hair growth also is provided.
