Microgravity increases cell migration. Phase contrast image of DLD1 control cells immediately after scratch from a T200 tip (a), 12 h post scratch wound (c) and 24 h post scratch wound (e). Comparative phase contrast image of SM DLD1 2 weeks post shifting to normal gravitational condition, 0 h (b), 12 h (d) and 24 h (f), scale = 200 μm. The representative graph (g) depicts 57.7% wound healing in SM after 12 hours, compared to 15.5% in control. The wound healing was 59% after 24 hours in SM compared to 38% in control.
