Figure 6. Like in mouse OPCs simulated microgravity shortens the cell cycle of human OPCs (hOPCs).

hOPCs were incubated in a chamber with 5% CO2 at 37°C, which was placed on the stage of a spinning disc confocal inverted microscope. Cells were imaged at 6 min intervals for a period of 26 h. Estimated cell cycle times and percentage of mitotic hOPCs for control and 0G treated cultures are shown. Values are expressed as mean ± SEM of four independent experiments. *p<0.05, **p<0.01, versus respective control.
