【摘要】：背景:人表皮干細胞和汗腺細胞的分離培養(yǎng)及鑒定,為探討人表皮干細胞再生汗腺的可行性打下基礎。目的:探討體外分離培養(yǎng)人表皮干細胞及汗腺細胞的有效方法。方法:采集不同年齡段的泌尿外科患者術后包皮組織,充分清洗消毒后去除皮下組織,將其修剪成0.5cm×0.5cm的皮片,用Ⅳ型膠原純化、富集成人表皮干細胞,倒置相差顯微鏡觀察細胞形態(tài):使用免疫熒光染色對成人表皮干細胞表型進行分析;CCK-8檢測細胞的增殖曲線;采用膠原酶消化法從人全層無損傷皮膚中分離提取汗腺細胞,并進行擴增和鑒定。結果:倒置相差顯微鏡下見分離培養(yǎng)的成人表皮干細胞呈卵圓形、細胞之間緊密相連,呈鋪路石狀,免疫熒光染色顯示細胞表達CK19、β1整合素。倒置相差顯微鏡下見汗腺細胞呈扁平多角形,表達汗腺細胞標志細胞CK7、18、19及CEA。結論:本實驗結果說明膠原酶消化法分離培養(yǎng)成人表皮干細胞及汗腺樣細胞是可行的。
[Abstract]:Background: isolation, culture and identification of human epidermal stem cells and sweat gland cells lay a foundation for exploring the feasibility of regeneration of sweat glands from human epidermal stem cells. Objective: to investigate an effective method for isolation and culture of human epidermal stem cells and sweat gland cells in vitro. Methods: the prepuce tissues of urological patients of different ages were collected, and the subcutaneous tissues were cleaned and disinfected, then the subcutaneous tissues were trimmed into 0.5cm 脳 0.5cm skin grafts, purified with type 鈪，
