Fig. 3From: Enhanced angiogenic potential of adipose-derived stem cell sheets by integration with cell spheroids of the same sourceAngiogenesis-related gene expression of monolayer ASC, ASC spheroid and ASC sheet. a Angiogenic growth factors HGF, VEGF, and FGF2. b Mature endothelial markers CD31, KDR and vWF. The gene expression was normalized to monolayer ASC (n = 3; *p < 0.05, **p < 0.01, ***p < 0.005 from the monolayer group; ##p < 0.01, ###p < 0.005 between the indicated groups)Back to article page
