Objective To establish a method for isolation and cultivation in vitro of human hair follicle outer root sheath cells.
目的建立毛囊外根鞘细胞的分离和培养方法。
AIM: to investigate the expression of cytokeratin K19 and proliferation capability in cultured follicular outer root sheath cells derived from plucked human sc alp hair.
目的：通过培养人毛囊外根鞘细胞群，观察其增殖活性及细胞角蛋白k 19的表达。
The hair is formed from cells just above the bulb, which also give rise to concentric zones of differentiated epithelial cells destined to form the inner and outer root sheaths.
毛球之上的细胞形成毛发，产生由分化的表皮细胞构成的同心环状区，形成内根鞘和外根鞘。
They were mainly consisted of epithelia differentiated towards cells of the outer root sheath, and the peripheral basal cells of the tumor lobules showed palisading arrangement.
组织病理学检查示肿瘤呈分叶状增生，与表皮相连，主要由向外毛根鞘分化的鳞状上皮组成，周边基底细胞排列成栅栏状。
