Abstract:Objective To determine the effect of platelet-derived growth factor-C (PDGF-C) on vascular endothelial cells (VECs) and mesenchymal stem cells(MSCs) cultured in vitro. Methods The VECs were isolated from thoracic aorta of SD rats and then cultured in vitro. Cryopreserved MSCs were cultured after water bath at 37℃. Cell counting and MTT assay were used to detect the effect of PDGF-C (0, 10, 20, 30, 40 and 50μg/L) on cell proliferation. Flow cytometry was used to detect cell phases. Transwell assay and cell scratch test were used to detect cell migration. Results PDGF-C significantly promoted the proliferation of VECs and MSCs, and increased the percentage of the cells arrested at S phase. Its effect on the VECs proliferation was found in a dose-dependent manner. PDGF-C of 20μg/L promoted the MSCs proliferation at a summit. PDGF-C also promoted the migration ability of cultured VECs and MSCs, especially on MSCs. Conclusion PDGF-C promotes the proliferation and migration of cultured VECs and MSCs.
