Figure 2. Effect of Ginkgolide A (GA) on WJMSCs homing capacity. (A) Transwell co-culture migration assay performed to examine the homing function. (B) CXCR4 and CXCR7 expression were determined after 20, 80 μM GA treatment in WJMSCs. The data are expressed as cell survival (fold-change) and are presented as the mean ± standard deviation. *P < 0.05 vs. control (without 6-hydroxydopamine (6-OHDA) damage), ##P < 0.01 vs. ctrl.
