Figure Lengend Snippet: Figure 3 Effect of partial gravity on the mandibular bone. (A) Histological findings and gene expression of insulin-like growth factor 1 (IGF-1) between 1/6G and 1G. The intensities were categorized into 4 groups (0e3) and randomly selected some fields. Scale bar Z 100 mm. (B) Histological findings of type I collagen at 1/6G and 1G. Scale bar Z 100 mm. (C) Quantification of mandibular bone using CT images between 1/ 6G and 1G. Scale bar Z 2 mm. Yellow box: measuring area; red dotted line: cutting plane of the images. *P < 0.05 and ***P < 0.001. ns, Not significant. TV: Tissue volume, BV: Bone volume, BS: Bone surface, BV/TV: Bone volume fraction.

Figure Lengend Snippet: Figure 5 Overview of the effect of lunar gravity on the jawbone. Bone formation was promoted, while resorption was not, under lunar gravity (1/6G), suggesting an association with mastication. DMP1: Dentin matrix acidic phosphoprotein 1, IGF-1: Insulin-like growth factor 1, SPP1: Secreted phospho- protein 1.
