Migration, Proliferation, and Differentiation of Cord Blood Mesenchymal Stromal Cells Treated with Histone Deacetylase Inhibitor Valproic Acid

VPA enhances migration of CB MSC towards a low SDF-1 gradient which is inhibited by CXCR4 and CXCR7 antagonists. CB-derived MSC were preincubated with or without 5 mM VPA for 3 h and allowed to migrate across Matrigel towards a low (20 ng/mL) or high (100 ng/mL) SDF-1 gradient. Cells were also incubated with CXCR4 antagonist AMD3100, CXCR7 antagonist CCX733, or the inactive CXCR7 antagonist CCX226. The data are based on two independent experiments; indicates statistically significant difference.
