Figure 3: Morphology of DPSCs culture in (A) FBS-M were broader and flattened in shape (B) in HS-M cells appeared spindle-shaped and (C) in SF/XF-M cells appeared flattened fibroblastic. Scale bar =100 μm. DPSCs: dental pulp stem cells; FBS-M: fetal bovine serum medium; HS-M: human serum medium; SF/XF-M: serumfree/xenofree medium.
