VPA exerts different effects on MSC proliferation and expression of pluripotency markers. (a) Cell proliferation was assayed by measuring the intracellular ATP released by CB-derived MSC after pretreatment with or without (control) 1, 5, or 10 mM VPA. The experiment was performed twice using 6 replicate wells per condition, and *P < 0.05 indicates statistically significant difference relative to control. (b) The expression of the pluripotency genes SOX2 and Oct-4 was evaluated by qRT-PCR using 18S mRNA as internal calibrator. The data is representative of two independent experiments and *P < 0.05 indicates statistically significant difference relative to control.
