Figure 5: Adipogenic differentiation of CD54-, CD54+, and unsorted AMSCs. Unsorted (A and D), CD 54- (B and E), and CD54+ (C and F) AMSCs were cultured in adipogenic induction medium (A, B, and C) or normal DMEM medium (D, E, and F). After 14 days, oil red O staining was used to illustrate intracellular lipid droplets.
