RESUMEN
ObjectiveTo investigate the effects of bone marrow stem cells autologous transplantation after acute myocardial infarction on local mRNA expression of SDF-1,Kit ligand,E-selectin,ICAM-1and VCAM-1.Methods Acute myocardial infarction models were established in 10 swine,which were randomized divided into placebo group (5 swine) and transplantation group (5 swine).After six months,hearts of placebo group and early transplantation group were harvested and mRNA expression of SDF-1,Kit ligand,E-selectin,ICAM-1 and VCAM-1 in infarcted myocardial region was detected.Results The mRNAs of SDF-1,Kit ligand,E-selection,ICAM-1 and VCAM-1 were expressed in the infarcted myocardial region of transplantation group six months after myocardial infarction,but it was not found in the placebo group.ConclusionsBone marrow autologous transplantation after acute myocardial infarction can promote local mRNA expression of SDF-1,Kit ligand,E-selectin,ICAM-1 and VCAM-1,which may be due to the paracrine effects of stem cells.
