Morphology of RCCs under VPA, metformin or a combination treatment. 786-O, 786-M-R and ACHN cells were cultured with VPA 1 mM (VPA), metformin 10 mM (Met) or a combination (V + M) and with or without TGF-β (2 ng/ml) for 48 h. Cell morphology was observed by bright field phase microscopy at 200× magnification. Bar, 100 μm
