To examine the effects of gravity on osteogenesis, medaka larvae were reared in water or gel under various conditions. For determining the effects on bone development in a state of motion, larvae were reared in water under normal gravity (1g) or hypergravity (5g) conditions. Also, to examine the direct effect of gravity on bone mineralization, larvae were embedded in low melting agarose gel containing alizarin complexone (ALC) and reared for three days under a normal gravity (1g), simulated-microgravity (s-μg) with use of a clinostat device, or 5g condition. Medaka reared in water under the 5g condition showed forward protruding jaws and spreading of the mineralized area of jaw teeth as compared to those reared under the 1g control condition. In addition, the direction of growth of the notochord in the fin region was changed upward in those reared under the 5g condition, accompanied by a part of acetylated tubulinpositive nerves also localized upward, while positive signals for DsRed, expressed by an osterix promoter, in osteoblasts were increased in the fin region. On the other hand, in medaka reared in gel, ALC signals in the fin ray of those in the s-μg condition were increased as compared to those in the 5g condition. Changes noted in medaka larvae over three days indicated osteogenesis adaptation to the specific gravity environment. The present results obtained with an experimental system are considered useful for examinations in the future regarding changes of osteogenesis, which will be needed to clarify the mechanism of the effects of gravity on bone development. ©2021 Jpn.

The Auxin Transport space experiment was conducted in 2016 and 2017 in the Japanese Experiment Module (JEM) on the International Space Station (ISS), with the principal objective being integrated analyses of the growth and development of etiolated pea ( Pisum sativum L. cv Alaska) and maize ( Zea mays L. cv Golden Cross Bantam) seedlings under true microgravity conditions in space relative to polar auxin transport. To clarify auxin dynamics at molecular levels, gene expression of PsPIN1 and ZmPIN1a mRNA, and their products detected by immunohistochemistry were also investigated. In addition, the use of microarray data technology with Medicago ( Medicago truncatula ) microarrays to characterize global changes in the transcript abundance of etiolated Alaska pea seedlings grown under microgravity conditions in comparison with those under artificial 1 G conditions on the International Space Station was reported here. Comprehensive analyses of endogenous plant hormones in etiolated pea and maize seedlings grown under microgravity conditions in space as well as on 1 G conditions on Earth have already performed in the space experiment. ©2020 Jpn.

However, the precise mechanism responsible for such phenomena is not ful ly understood yet. Changes of the distribution of satellite cells and/ or myonuclei have been also noted in atrophied or hypertrophied skeletal muscle fibers, suggesting that the number and/or function of these parameters play essential roles in the regulation of morphological properties of muscle and muscle fibers. Thus, the roles of satellite cells and/or myonuclei in the regulation of morphological properties of anti-gravitational muscle, soleus and adductor longus, in response to the level of mechanical stress, with or without association of macrophage-related factors, were briefly reviewed. It was suggested that a regulatory network among macrophage, interleukin-6, heat shock transcription factor 1, and activation of transcription factor 3 may play a crucial role for the modulation of skeletal muscle mass and function, which are also influenced by activation of satellite cells and distribution of myonuclei. ©2020 Jpn.
