Analyses of efficiency of forming sarcospheres, and wound healing assay on Saos2 and MG63 cell lines after VPA and DAC treatment. (a) SSFE showing an increase of sarcospheres formation both in Saos2 and MG63cells after drug treatments; (b) Wound healing assay showing that VPA and DAC a decrease of wound size in treated cells. * p < 0.005, ** p < 0.001, *** p < 0.0001 compared to the untreated cells
