ABSTRACT
Objective · To investigate the effect of poly (L-lactic acid caprolactone) (PLCL)/gelatin electrospinning on the angiogenesis differentiation of endothelial progenitor cells (EPCs).Methods· Rat bone marrow-derived EPCs were isolated and cultured,then identification was performed.After preparation of PLCL/gelatin blend electrospun scaffold,scanning electron microscopy and water contact angle test were carried out.EPCs were grown on PLCL/gelatin electrospinning and CCK8 was used to detect cell proliferation.The expression of vascular endothelial growth factor (Vegf) and kinases insert region receptor (Kdr) was observed by RT-PCR and the expression of VEGF protein was observed by Western blotting.Results· The density gradient centrifugation combined with differential adherence method could effectively isolate EPCs.PLCL/gelatin electrospun nanofibers were porous,and the hydrophilic properties were favorable for cell adhesion,and EPCs grew well on the scaffold.The expression of Vegfand Kdr gene in PLCL/gelatin group was higher than that in control group (P=0.000),and the expression of VEGF protein was also increased (P=0.000).Conclusion · PLCL/gelatin is an ideal scaffold for tissue engineering,and it can promote the angiogenesis differentiation of EPCs.
