Figure 1. — Schematic of fibro-adipogenic progenitors (FAPs). FAPs are muscle resident multipotent mesenchymal stem cells that can differentiate into adipocytes, fibroblasts or osteocytes (under specific conditions). They express key surface markers such as platelet-derived growth factor receptor α (PDGFRα), stem cell antigen-1 (Sca-1) and cluster of differentiation 34 (CD34).
