PDGF-BB employs PDGFR- β in hemSCs. shRNA-mediated knockdown of PDGFR- α ( a ) and PDGFR- β ( b ) in hemSCs at sub-passage 1 (subP1; following 2 weeks of puromycin selection) and sub-passage 6 (six serial passages after puromycin selection) (* P <0.05 compared with control shRNA).

( d ) Schematic illustrating the findings of the study and our working hypothesis. High levels of PDGF-BB from hemSCs during proliferation mediate intracellular signaling through PDGFR- β (predominantly PDGFR- ββ homodimer with contribution from PDGFR- αβ heterodimer) to inhibit C/EBP α and PPAR γ expression and adipogenesis (i.e., involution). Upon regression of the vessels and removal of the PDGF-BB source, adipogenesis is triggered
