简介：
Overview
This study presents a protocol for the isolation and separation of two smooth muscle cell types from the lacrimal gland: myoepithelial cells (MECs) and pericytes. Using genetic labeling, the method enables purification for comparative analysis of healthy and diseased cells, thereby contributing to our understanding of cell function and regenerative abilities.
