Abstract:

BACKGROUND: Vascular endothelial growth factor is a potent angiogenesis and permeability inducible factor. Vascular endothelial growth factor 165 and vascular endothelial growth factor 121 are mainly expressed in vivo, with a strong role of angiogenesis.
OBJECTIVE: To observe the feasibility of vascular endothelial growth factor 165 gene transfected bone marrow mesenchymal stem cells to differentiate into vascular endothelial cells.
METHODS: Bone marrow derived mesenchymal stem cells were isolated and collected from 50 g Sprague-Dawley rats,and identified by flow cytometry. The plasmid pGLV-EF1a carrying a vascular endothelial growth factor 165 gene was transfected to the mesenchymal stem cells using lentiviral. Expression of green fluorescent protein was observed under a fluorescence microscope.
RESULTS AND CONCLUSION: After 12 hours of transfection, expression of green fluorescent protein was observed, increased at 48 hours, peaked at 72 hours and gradually declined thereafter. Results prove that vascular endothelial growth factor 165 gene transfected bone marrow mesenchymal stem cells have the expression of green fluorescent protein, indicating successful transfection. It is feasible to induce bone marrow mesenchymal stem cells to differentiate into vascular endothelial cells.

Key words: stem cells, vascular endothelial growth factors, transfection, green fluorescent proteins
