Experimental study of the effects of marrow mesenchymal stem cells transfected with hypoxia-inducible factor-1alpha gene.

ABSTRACT:

Objective

To construct the eukaryotic expression vector hypoxia-inducible factor 1alpha-pcDNA(3.1) and to investigate its transfective efficiency into mesenchymal stem cells (MSCs) in vitro and the expression of HIF-1alpha gene in MSCs.

Methods

mRNA of Wistar Rats' myocardial cells was extracted, and cDNA was synthesized with Reverse Transcription Kit, HIF-1alpha was amplified by polymerase chain reaction (PCR), and constructed into pcDNA(3.1). Transfected HIF-1alpha-pcDNA(3.1) into MSCs by liposome mediated method. The expression of HIF-1alpha in the cells was detected by Western Blot Analysis and ELISA.

Results

Eukaryotic expression vector HIF-1alpha-pcDNA(3.1) was constructed successfully. Analyzed by flow cytometer, The MSCs' surfaces mark were CD44+, SH3(CD73)+,
