From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.

背景：胚胎干细胞来源于发育早期囊胚的内细胞团，适当条件下能在体外维持未分化状态、正常二倍体核型及无限增殖能力，且具有多向分化潜能，能够发育分化成机体3个胚层的所有类型细胞。
