The epidermis, as a defensive barrier, is a consistent trait throughout animal evolution. During post‐larval development, the zebrafish epidermis thickens by stratification or addition of new cell layers. Epidermal basal stem cells, expressing the transcription factor p63, are known to be involved in this process. Zebrafish post‐larval epidermal stratification is a tractable system to study how stem cells participate in organ growth.

斑马鱼幼体发育过程中表皮分层的动态

表皮作为防御屏障，是整个动物进化过程中的一致特征。在幼体后期发育过程中，斑马鱼表皮通过分层或添加新细胞层而变厚。已知表达转录因子 p63 的表皮基底干细胞参与了这一过程。斑马鱼幼体后表皮分层是研究干细胞如何参与器官生长的易处理系统。
