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。
The hair shaft and inner root sheath move together as the hair grows toward the surface: the outer root sheath remains fixed in position.
毛干和内根鞘当到达体表时融合在一起：外根鞘仍然保持在原来的位置。
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。
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。
