BM-MSCsCD105+, CD73+, CD90+, CD45−, CD34−, CD14−, CD11b−, CD79 alpha, CD19−, and HLA-DR− [3739]Promote cell proliferation, collagen synthesis, growth factor release, wound contraction, neovascularization, and cellular recruitment to wounds [4146].
ADSCsCD31−, CD34+/−, CD45−, CD90+, CD105−, and CD146− [4750]Increase cell proliferation, collagen synthesis, promote neovessel formation, and tissue remodeling [47, 51, 52].
EPCs CD34+, VEGFR-2+, and CD133+ [29, 40]Promote vascularization secrete proangiogenic growth factors and cytokines, and differentiate into endothelial cells [5355].
BMNCshematopoietic progenitor cell markers: CD133+, CD117+, and CD34
MSCs markers and endothelial progenitor population: CD34+/−, CD133+, and VEGFR2+ [56, 57]
Secrete angiogenic growth factors decrease local inflammation, and promote vascularization differentiate into endothelial cells [5863].
FibrocytesCD 34+, CD11b+, CD13+, MHC II+, CD86+, CD45+, collagen-1+, procollagen-1+, CD3−, CD4−, CD8−, CD19−, and CD25− [64, 65]Increasing cell proliferation ECM deposition, wound contraction, and vascularization.
Secrete of growth factors and chemokines [6570].
