Abstract Random positioning machine (RPM) and diamagnetic levitation are two essential ground-based methods used to stimulate the effect of microgravity in space life science research. However, the force fields generated by these two methods are fundamentally different, as RPM generates a dynamic force field acting on the surface in contact with supporting substrate, whereas diamagnetic levitation generates a static force field acting on the whole body volume of the object (e.g. cell). Surprisingly, it is hardly studied whether these two fundamentally different force fields would cause different responses in mammalian cells. Thus we exposed cultured MC3T3-E1 osteoblasts to either dynamically stimulated… More >
