ABSTRACT
Objective To investigate the repair and reconstruction mechanism of stromal cell derived factor-1(SDF-1) on rat abdominal aorta grafts.Methods Male Sprague-Darley rats received abdominal aorta grafts from male Wistar abdominal arteries.Immunohistochemical staining(IHC) was performed to detect the SDF-1 expression.The expression of CXCR4,the receptor of SDF-1,was demonstrated by RT-PCR.(Results) SDF-1 was expressed on the endothelium all the time during the course of the abdominal aorta grafts in the bodies of recipients.Furthermore,it was found that there was a significant relationship between the expression of SDF-1 on the endothelia and the thickness of the neointima of the rat abdominal aorta grafts.On the other hand,CXCR4 was detected within the abdominal aorta grafts.Conclusions Stem cells could be mobilized by SDF-1 to the abdominal aorta grafts and differentiated into smooth-muscle like cells.Furthermore,SDF-1 is predictive of grafts arteriosclerosis and the subsequent development of chronic graft dysfunction(CGD).
