As shown in Figure six, approximately 40 of donor BMMSCsGFP underwent osteogenic differentiation into Osx+ osteoblast progenitors (Fig. 6AD).

Within this preclinical study, we revealed that allogeneic MSC therapy could serve as a promising anabolic option in the management of GIOP, in that systemic infusion of BMMSCs S TEM C ELLS T RANSLATIONAL M EDICINE�AlphaMed PressSui, Hu, Zhang et al.Figure six.
