Platelet-derived growth factor receptor-β-positive telocytes in skeletal muscle interstitium.
Bottom Line: We found that in human skeletal muscle TCs were constantly located around intermediate and small blood vessels and endomysial capillaries.Telocytes were constantly located in the perivascular or pericapillary space, as confirmed by double staining of c-kit/CD31, PDGFR-β/CD31 and PDGFR-β/α-smooth muscle actin, respectively.Laminin labelling showed that TCs are not enclosed or surrounded by a basal lamina in contrast to mural cells.

Mentions: We show here, based on in situ double immunolabelling, the presence of c-kit-positive TCs in skeletal muscle, surrounding small blood vessels marked by the endothelial marker CD31 (Fig. 1A), or located in the vicinity of endomysial capillaries (Fig. 1A and B), results confirmed by electron microscopy (Fig. 1C). As shown previously, perivascular TCs synthesize VEGF (Fig. 2).
