简介：
Overview
This article demonstrates three tissue preparation techniques for immunohistochemical visualization of rat retinal microvascular pericytes: cryo-sections, whole-mounts, and hypotonic isolation of the vascular network. These methods are crucial for addressing questions in ophthalmology, such as pericyte proliferation and migration.
