Fibro-Adipogenic Progenitor Isolation, Expansion, and Differentiation from the Spiny Mouse Model

Overview

This protocol outlines the isolation of skeletal and cardiac muscle fibro-adipogenic progenitors (FAPs) from spiny mice (Acomys) using enzymatic dissociation and fluorescence-activated cell sorting. The method provides reliable enzyme digestion and antibody staining for effective sorting and in vitro culture of FAPs.
