Advances in Space Research, 38(6) 1112-1116, 2006 Peer-reviewedTo investigate the effects of gravity on morphogenesis at the cellular level, we have proposed a new experimental system with micromeres from sea urchin embryos [Izumi-Kurotani, A., Kiyomoto, M. Morphogenesis and gravity in a whole Amphibian Embryo and in isolated blastomeres of sea urchins, in: Marthy, H. -J. (Ed.), Developmental Biology Research in Space. Adv. Space Biol. Med. vol. 9, Elsevier, Amsterdam, pp. 83-99, 2003]. We studied spicule formation in cultured micromeres of sea urchin embryo under various conditions of gravity: hypergravity by a centrifuge and simulated microgravity in a vertical clinostat. Spicule elongation was suppressed under both experimental conditions. © 2005 COSPAR.

Advances in Space Biology and Medicine, 9 83-99, 2003Fertilization and subsequent embryogenesis of newts occurred normally under microgravity in two Astronewt flight experiments. By accumulation of the results from the amphibian flight experiments including 'Astronewt', it is considered that gravity has rather small effects on the early development of amphibian eggs. However, some temporary abnormalities, which recover in the course of the further developmental process, have been observed. Some regulations may occur in whole embryos. For a thorough knowledge about the role of gravity in morphogenesis, we need to investigate the gravitational effects on a single cell in a whole embryo. We propose a new experimental system with sea urchin embryos and micromeres for further studies at a cellular level of the effects of gravity on morphogenesis. © 2003 Elsevier Science B.V.
