Outline of Final Research Achievements

We performed three-dimensional construction of collagen fibers in the osteogenic phase by using FIB-SEM. Furthermore, since this analysis extends to a cubic region of 25 micrometers per side, it was possible to capture a cellular network containing multiple osteocytes simultaneously. From these observations, processes extending from the osteoblasts to the matrix side have a certain regularity so as to avoid bundled collagen fibers. Furthermore, the bones pretreated with BAPN, which inhibits collagen fiber aggregation, cell processes extending from osteoblasts have no specific orientation. Thus, it has been revealed that changing the nature of bone matrix affects osteocyte network formation.

Academic Significance and Societal Importance of the Research Achievements

骨は外界の力によってその形を変化させる。その変化には細胞が主導となって関与しているのか細胞から産生された基質が力によって再配列を引き起こし変化しているのかは明確な答えはなかった。今回我々は、骨基質のコラーゲン線維の立体構築と骨内でネットワーク形成をなしている骨細胞を同時にとらえることができ、この両者の関係をみることができた。そして、集束したコラーゲン線維が細胞ネットワークの方向性を変化させていることを突き止めた。よって、骨梁の微細構造を形成する細胞性ネットワークの初期過程には細胞による形態形成のみならず、基質が自ら変化することも影響を与えることが示唆された。
