Spicule formation by the cultured micromere of sea urchin was used as a model for the morphogenesis in biomineralization to be adapted as an experimental system in space. Several experiments were carried out in the different gravity environment to examine a role of gravity in the cells isolated from whole embryo. In the experiments of centrifugation or clinostat spicule elongation was suppressed. In a series of parabolic experiment by airplane the elongation of spicule after the parabolic flight was suppressed in each several stage cells. The negative effect for biomineralization of sea urchin seems the same response of mammal skeleton for microgravity and expected finding will help the understanding of phenomena. Besides, period-specific sensitivity for gravity appeared partially. These finding are important in planning for space experiment.
