Figure 2From: Role of stem/progenitor cells in reparative disordersFibro/adipogenic progenitors (FAPs) in skeletal muscle. Confocal image of a cluster of muscle fibers harvested from non-damaged muscle showing the relationship between mesenchymal progenitors expressing nuclear GFP under the control of the PDGFRα locus and fiber-associated blood vessels positive for CD31 (red). Nuclei are stained blue.Back to article page
