However, details of osteoclast activity in low gravity remain unknown. We have developed a unique osteoclast culture system using biodegradable and unbiodegradable ceramic discs. Using an ultrasensitive intracellular calcium analyzing system, we are studying change in intracellular calcium of active osteoclasts cultured on biodegradable ceramics and quiescent osteoclasts cultured on unbiodegradable ceramics. It is highly possible that low gravity changes function of calcium channels in osteoclasts and will change the intracellular calcium concentration very quickly. It has been shown that intracellular calcium affects osteoclast bioactivity. Hence, parabolic flight experiments will be able to clarify the mystery of osteoclast in space medical biology., 形態: カラー図版あり, 資料番号: AA0064297047},
