Abstract

Abstract: BACKGROUND: Endothelial dysfunction is an early predictor of atherosclerosis and cardiovascular disease. Umbilical cord mesenchymal stem cell transplantation provides the possibility for the treatment of vascular injury.
OBJECTIVE: To explore the effect of overexpression of interleukin-8 receptor A/B on migration of human umbilical cord mesenchymal stem cells.
METHODS: Primary cultured human umbilical cord mesenchymal stem cells and human umbilical vein endothelial cells were transfected with adenovirus vector containing interleukin-8 receptor A/B. Confocal immunofluorescence microscopy and western blot assay were used to observe the expression of interleukin-8 receptor A/B in cells. CCK-8 assay, competition test and adhesion test were used to detect the effects of interleukin-8 receptor A/B overexpression on cell proliferation, competitiveness and migration.
RESULTS AND CONCLUSION: The fluorescent adenovirus vector overexpressing interleukin-8 receptor A/B has no significant effect on cell proliferation. However, the competition and migration abilities of human umbilical cord mesenchymal stem cells overexpressing interleukin-8 receptor A/B were significantly higher than those of human umbilical vein endothelial cells overexpressing interleukin-8 receptor A/B (P < 0.05). It is concluded that interleukin-8 receptor enhances the migration ability of human umbilical cord mesenchymal stem cells and promotes adhesion to injured endothelium.
