Microgravity has advantages for the cultivation of tissues with high fidelity; however, tissue formation requirescellular recognition and adhesion. We tested the hypothesis that simulated microgravity does not affect celladhesion. Human colorectal carcinoma cells were cultured in the NASA Rotating Wall Vessel @WV) under lowshear stress with randomization of the gravity vector th...
