PD-L2 overexpression enhances migration of EC cells. (A) Western blot analysis of PD-L2 and GAPDH protein levels in PD-L2⁺ PCEM004b cells. Blots are representative of one of three separate experiments. PD-L2 densitometry values were normalized to GAPDH used as loading control. Densitometric values shown are the mean ± SE of three separate experiments. *p < 0.05 vs control cells. (B) Wound healing assays for PCEM004b cells after PD-L2 overexpression. All experiments were repeated three times. T0 h (used for consistency with other time-points). Data are presented as the mean ± SD. **p < 0.01 vs control.
