Fig. 4From: Transplantation of EPCs overexpressing PDGFR-β promotes vascular repair in the early phase after vascular injuryEPCs tracing in vivo. a Labeled pEGFP-N2-EPCs and b pEGFP-N2- PDGFR-β-EPCs were injected into the mice after vascular injury and attached to the vascular injury site on day 7. Arrows indicate EPCs (n = 5). L, lumen; M, media. Scale bar = 50 μmBack to article page
