| Outline of Final Research Achievements |
The CD34-positive cell number was significantly higher in the cultured with microgravity groups than in the normal control group. EPC number was significantly increased in the cultured with microgravity and earthgravity group compared to the control groups. dEPC-CFU were significantly increased in the cultured with both gravity group compared to the normal control. Furthermore, VEGF-A expression increased in the cultured with both gravity condition group compared to the normal control.In Conclusion, stimulation of MNC-QQc cells with MG increased the number of EPCs, such as CD34-positive cells, by enhancing their proliferation capacity. Furthermore, earth culture after microgravity stimulation induced vasculogenic differentiation of CD34 cells.
This study indicated that MNC-QQc in combination with Micro gravity-Earth gravity conditions might be a more effective angiogenic cell expansion culture method and could be a valuable tool for therapeutic vasculogenesis and tissue regeneration
