Colony-formation assay and endothelial abilities of Lnk siRNA-transfected mouse KSL cells in vitro. (a) Representative images of a small colony and a large colony. (b) The number of EPC colonies was assessed after Lnk and control siRNA transfection. Average number of EPC colonies per dish of Lnk siRNA-transfected KSL cells was significantly greater than that of control siRNA-transfected KSL cells. (c) mRNA expressions of mVE-Cad, mVEGF and mAng-1 were normalized to GAPDH. (d) Proliferation and migration activities of mouse BM-derived cultured KSLs in response to Lnk and control siRNA. The proliferation activity is expressed as optical density (490 nm). The migration activity is expressed as the number of migrated cells to SDF-1. *P<0.05 and **P<0.001 vs control siRNA.
