ABSTRACT
Objectives; To identify the roles of Notch - 1 gene for survivaland differentiation of mesenchymal stem cells ( MSCs) into neurons by way of RNA interference ( RNAi) technique to suppress expression of Notch - 1 gene. Methods; Firstly, construct mNotch - 1 short hairpin RNA (mNotch -IshRNA) and then to oberve configuration of MSCs transfected by mNotch - IshRNA; MTT was employed to evaluate the survival ratio of MSCs before transfection, 24 hours and 3 days after transfection, respectively; agents, such as BDNF, retinoid acid, were obtained to induce MSCs transfected by mNotch - IshRNA in vitro and expression of Nestin, NSE and NF200( neuron marker agent) and GFAP( neural glial cell marker agent) were determined by immunocytochemistry stain technique. Results:
The cell cubic configuration was enforced and expression of notch - 1 gene vanished by transfection of mNotch -IshRNA. The survival ratio of MSCs by transfection decreased and there was significant differences between non - ransfection and transfection - controlling group after 24 hours and 3 days of transfection ( P
