简介：
Overview
This article presents a method for establishing explant cultures of zebrafish keratocytes, which serve as an in vitro model for studying collective cell migration and epithelial wound healing. The procedure involves removing scales with attached epithelial tissue from adult zebrafish and culturing them to observe cell behavior.
