©2019 The Japan Institute of Metals and Materials In this study, we focused on the preferential orientation of the extracellular matrix (ECM) of bone, since ECM orientation has been shown to significantly affect the mechanical functions of bones. Bone analysis is in most cases based on the premise that the apatite crystallizes on the collagen template such that its c-axis is parallel with the running direction of the collagen fibril. Bone regeneration analysis has also been discussed assuming that the apatite c-axis orientation reflects collagen orientation. To understand the regeneration processes of both collagen and apatite individually, the preferential orientations of apatite and collagen in regenerated bone were simultaneously analyzed using a bone regeneration model of mouse femur with an 0.8-mm drill hole defect. The defects in mouse femur were filled with mineralized bone matrix, which shows an intact mineral density. However, the directions of orientation of the collagen and apatite deviate from the femur longitudinal axis in the regenerated bone. Moreover, electron diffraction analysis revealed that the apatite c-axis aligned along the extended axis of a collagen fibril both in regenerated and intact bones, indicating that the direction of the apatite c-axis is regulated by collagen fibril orientation even in the regenerated bone. In conclusion, the less-oriented apatite crystallite observed in the regenerated bone was shown to be formed due to the less-oriented collagen fibrils.

In vitro synthesis of bone tissue has been paid attention in recent years; however, current methods to fabricate bone tissue are still ineffective due to some remaining gaps in the understanding of real in vivo bone formation process, and application of the knowledge in bone synthesis. Therefore, the objectives of this study were first, to perform a systematic and ultrastructural investigation of the initial mineral formation during intramembranous ossification of mouse calvaria from a material scientists' viewpoint, and to develop novel mineralization methods based on the in vivo findings. First, the very initial mineral deposition was found to occur at embryonic day E14.0 in mouse calvaria. Analysis of the initial bone formation process showed that it involved the following distinct steps: collagen secretion, matrix vesicle (MV) release, MV mineralization, MV rupture, and collagen fiber mineralization. Next, we performed in vitro mineralization experiments using MVs and hydrogel scaffolds. Intact MVs embedded in collagen gel did not mineralize, whereas, interestingly, MV nanofragments obtained by ultrasonication could promote rapid mineralization. These results indicate that mechanically ruptured MV membrane can be a promising material for in vitro bone tissue synthesis. © 2019 The Authors. journal Of Biomedical Materials Research Part A Published By Wiley Periodicals, Inc.

Three-dimensional (3D) cell constructs composed only of cells and cell-secreted extracellular matrix have been attractive biomaterials for tissue engineering technology; however, controlling construct morphology and eliminating dead cells after fabrication remain a challenge. It has been hypothesized that moderate stress could shape constructs and eliminate dead cells. The purpose of this study was to establish an easily available technology for shaping 3D cell constructs and eliminating dead cells postfabrication. To achieve these objectives, spherical cell constructs composed of L-929 fibroblasts were processed using different sized syringe needles. Our results revealed that large-scale rod-shaped cell constructs could be fabricated, and that their diameters could be controlled according to the size of the syringe needle. Additionally, cell viability assays showed that >94% of cells in the rod-shaped constructs were viable, suggesting that dead cells, which have low adhesion force, were dispersed when compressive stress was applied during passage through the needle. The technology described in this study will be promising for future tissue engineering, especially for fabricating elongated tissues such as nerves and blood vessels. © 2019 Wiley Periodicals, Inc.
