Background and Aim: In recent years, biophysical forces especially microgravity increasingly has been used for cell manipulation, in particular cell differentiation and tissue engineering. Microgravity, as a mechanical factor, has been demonstrated to stimulate cell proliferation and differentiation. In this study, we investigated the impact of simulated microgravity condition generated by one-axis clinostat, on cell cycle and apoptosis rate of adipose derived stem cells (ADSCs).
Material and Methods: After isolation and characterization of human ADSCs, they were exposed to simulated microgravity condition generated by one-axis clinostat, for 3 days. After 3 days of clinorotation, control and microgravity samples were stained with PI, then, we evaluated cell cycle and apoptosis rate.
Results: Isolated cells expressed mesenchymal markers and were able to differentiate into adipocytes and osteocytes. Our results showed that 3 days of simulated microgravity induced by one-axis clinostat had no statistically significant effects on the cell cycle and apoptosis rate.
Conclusion: Previous studies have shown that simulated microgravity induced by 3-axis clinostat or RPM altered cell cycle and increased apoptosis rate. Based on our data, it seems that shear stress generated by one-axis clinostat is much less than that generated by three-axis clinostat. Therefore, we recommend use of one-axis clinostat for evaluation of cell differentiation and cell therapy under microgravity conditions for the future studies.
