MSCs have generally been shown to express Sca-1, PDGR- (CD140a), NST, and CD133 (9, 13, 15, 30), whereas GFP-negative cells do not express CD133 and express variable levels of PDGR-. immunofluorescence analysis for Cytochalasin B clean muscle-specific caldesmon, nearly all cells were immunoreactive ( em SI Appendix /em , Fig. S12 em D /em , em 1C4 /em ). These results demonstrate that fibroblast-like cells from embryos have the capacity to mature into cell types much like those of pericytes. Conversation This study establishes that embryonic cells of the fibroblast class constitute a rich human population of subtypes. From a transgenic reporter mouse collection in which a VEGF promoter fragment drives the manifestation of GFP, ethnicities containing Cytochalasin B subpopulations of GFP-positive and GFP-negative cells with the typical characteristics of…
