    Tendon exhibits the capacity to be stretched and to return to its original length without suffering structural damage in vivo, a capacity known as elastic recoil. Collagen fibres are aligned longitudinally and elastin fibres mostly run parallel to collagen fibres in tendon. However, their interactions and contributions to tendon elastic behaviours are not well understood. The present study examined functional roles of collagen and elastin in tendon elastic behaviours using a variety of mechanical tests. We prepared three types of fascicle specimens from mouse tail tendon: fascicles freshly isolated, those digested with elastase in PBS to selectively remove elastin, and those incubated in PBS without elastase. A quasi-static tensile test demonstrated that elastase-treated fascicles had higher tangent moduli and strength compared to fresh and PBS fascicles. Cyclic stretching tests showed that fresh and PBS fascicles could withstand cyclic strain at both small and large amplitudes, but elastase-treated fascicles could only behave elastically to a limited degree. Fibre-sliding analysis revealed that fresh fascicles could be elongated both through stretching of collagen fibers and through movement of the fibres. However, elastase-treated fascicles could be stretched only via fibre stretching. This evidence suggests that normal tendons can be extended through both fibre stretching and fibre sliding, whereas tendons without elastin can only extend as much as collagen fibers can withstand. Accordingly, collagen fibres mainly contribute to tendon elastic behaviours by furnishing rigidity and elasticity, whereas elastin provides tendon viscoelasticity and also enables sliding of collagen fibres during elastic behaviours. Statement of significance: The present study revealed distinct mechanical functions of collagen and elastin fibres in elastic behaviours of mouse tail tendon fascicle using a variety of mechanical tests at both microscopic and macroscopic levels. It was demonstrated that collagen mainly governs tendon fascicle rigidity and elasticity, but only possesses limited extensibility, whereas elastin contributes to viscoelasticity and collagen fibre sliding, enabling elastic recoil behaviour against relatively large deformation. By their interactions, tendon can be elongated without suffering major structural damage and withstand a large magnitude of tensile force in response to mechanical loading. Such information should be particularly useful in designing collagen-based biomaterials such as artificial tendons, in that previous studies have merely considered collagen without incorporation of elastin.

    Adult mammals are known for their poor ability to regenerate tissues, including tendons. On the other hand, urodeles have become an important model in regenerative studies for their remarkable ability to regenerate various body parts and organs throughout life, such as limbs, retinas, or even the brain. However, little is known about their capacity to regenerate injured tendons. If newts can also repair tendons without scar formation, they may be a suitable animal model for tendon regeneration studies in other adult vertebrates. Therefore, the present study used Iberian ribbed newts to characterize mechanical and structural regeneration of tendons following transection, using tensile tests and multiphoton microscopy. A digital flexor tendon in a hindlimb was transected either partially or completely, and regenerated tendon was examined 6 and 12 weeks after the operation. Tensile strength of regenerated tendons was significantly less than normal at 6 weeks, but was remarkably recovered at 12 weeks, reaching levels comparable to those of uninjured tendons. On the other hand, mouse tendons demonstrated poor recovery of strength even after 12 weeks. Multiphoton microscopy revealed that tendon-like collagenous tissue bridges residual tendon stubs in newts, but disorganized scar-like tissue filled the injured location in mice. These findings highlight the remarkable capacity of newts to recover from tendon injury and confirm the utility of newts as a model to study tendon regeneration.

    In recent years, three-dimensional (3D) cell culture has been attracting attention as a cell culture model that mimics an environment closer to that of a living organism. It is known that there is a close relationship between cell nuclear shape and cellular function, which highlights the importance of cell nucleus shape analysis in the 3D culture. On the other hand, it is difficult to observe the cell nuclei inside the 3D culture models because the penetration depth of the laser light under a microscope is limited. In this study, we adopted an aqueous iodixanol solution to the 3D osteocytic spheroids derived from mouse osteoblast precursor cells to make the spheroids transparent for 3D quantitative analysis. With a custom-made image analysis pipeline in Python, we found that the aspect ratio of the cell nuclei near the surface of the spheroid was significantly greater than that at the center, suggesting that the nuclei on the surface were deformed more than those at the center. The results also quantitatively showed that the orientation of nuclei in the center of the spheroid was randomly distributed, whereas those on the surface of the spheroid were oriented parallel to the surface of the spheroid. Our 3D quantitative method with an optical clearing technique will contribute to the 3D culture models including various organoid models to elucidate the nuclear deformation during the development of the organs. Insight box Although 3D cell culture has been a powerful tool in the fields of fundamental biology and tissue engineering, it raises the demand for quantification techniques for cell nuclear morphology in the 3D culture model. In this study, we attempted to optically clear a 3D osteocytic spheroid model using iodixanol solution for the nuclear observation inside the spheroid. Moreover, using a custom-made image analysis pipeline in Python, we successfully quantified the nuclear morphology regarding aspect ratio and orientation. Our quantitative method with the optical clearing technique will contribute to the 3D culture models such as various organoid models to elucidate the nuclear deformation during the development of the organs.

    Endochondral ossification is the process of bone formation derived from growing cartilage duringskeletal development. In previous studies, we provoked the osteocyte differentiation of osteoblast precursor cells under a three-dimensional (3D) culture model. To recapitulate the endochondral ossification, the present study utilized the self-organized scaffold-free spheroid model reconstructed by pre-chondrocyte cells. Within 2-day cultivation in the absence of the chemically induced chondrogenesis supplements, the chondrocyte marker was greatly expressed in the inner region of the spheroid, whereas the hypertrophic chondrocyte marker was strongly detected in the surface region of the spheroid. Notably, we found out that the gene expression levels of osteocyte markers were also greatly upregulated compared to the conventional 2D monolayer. Moreover, after long-term cultivation for 28 days, it induced morphological changes in the spheroid, such as cellular hypertrophy and death. In this study, in order to recapitulate the initial stage of the endochondral ossification, we highlighted the potentials of the 3D culture method to drive the hypertrophic chondrocyte differentiation of the pre-chondrocyte cells.

    Understanding in multicellular behaviors in three-dimensional (3D) culture models such as organoids is important to help us better comprehend the mechanisms of the morphogenesis and functions of diverse organs in vivo cellular environment. In this study, we elucidated the multicellular behaviors of the osteocytic spheroids in response to the chemically induced osteogenesis supplements (OS). Particularly, we conducted 1) size change measurement, 2) fusion experiment, and 3) collagen embedding experiment of spheroids, in response to the OS. We found out that the OS alters the multicellular behaviors of the spheroid by greater reduction in the size change measurement and slowing down the speed of fusion experiment and collagen embedding experiment of the spheroids. We also highlighted that the driving force of these changes was the tight actin filaments generated on the surface of the spheroids. Hence, the results altogether indicate that the spheroid model exerted the different multicellular behaviors against the differentiation capability. This study will contribute to understanding the multicellular behaviors of the 3D culture model reconstructed by the cells with greater cell-cell interaction force.

    The deformation of the cell nucleus may cause dispersion of chromatin and eventually enhance transcription, translation, and protein expression. If this happens in the hypertensive artery, an excessive stretch of smooth muscle cell (SMC) nuclei caused by hypertension may provoke wall thickening. Here, we measured deformation of SMC nuclei in rabbit thoracic aortas stretched in different directions. Thin 0.2-mm-thick specimens were sliced in the direction perpendicular to their axial and circumferential directions, and stretched in the circumferential and axial directions, respectively. The deformation of the actin filament (AF) network was similar to that of the whole tissue, whereas the deformation of the nucleus was significantly smaller than the others. Notably, the nucleus seldom deformed when the tissue was stretched in the axial direction. A novel cell model in which the nucleus is connected to the extracellular matrix via the AF network successfully explained the relative unresponsiveness of the nucleus to the axial stretch. It has been pointed out that stress is maintained constant in the circumferential direction but not in the axial direction in the artery wall during hypertension. The relative unresponsiveness of the nucleus to the axial stretch represented in this study explains this phenomenon.

    Osteocytes play an important role to modulate the bone remodeling and are also known as terminally differentiated cells originated from the osteoblast precursor cells, but its differentiation mechanism remains unclear. Since an efficient in vitro method to evoke the osteocyte differentiation from the osteoblast precursor cells has not been established, we conducted the comparative gene expression analysis for mouse pre-osteoblast MC3T3-E1 cells in order to elucidate the key factors to induce the osteocyte differentiation from the pre-osteoblast cells. In this study, we prepared four different culture environments by modulating their cell-substrate interaction and cell–cell interaction; (i) low and (ii) high cell density on the adhesive culture models, and (iii) low and (iv) high cell density on the non-adhesive floating culture models. By comparing these conditions in terms of cell-substrate and cell–cell interaction, we showed that the elimination of cell-substrate interaction under non-adhesive floating culture greatly up-regulated the gene expression of osteocyte markers in the pre-osteoblast cells. Moreover, the presence of moderate cell–cell interaction in the non-adhesive spheroid culture further enhanced the up-regulation of osteocyte markers for the pre-osteoblast cells. The results altogether suggest the most appropriate culture environment to induce the in vitro osteocyte differentiation of pre-osteoblast cells.

    In this study, we fabricated and evaluated a cartilage scaffold-free tissue (SFT), which is a three-dimensional cell assembly derived from mouse chondroprogenitor ATDC5 cells. After long-term culture without addition of chemical differentiation supplements, hypertrophy of cells within the spheroids was confirmed, and apoptosis was also observed from the center of the spheroids. This is a phenomenon observed in the initial stage of endochondral ossification, and is a result showing the structural effect of the three-dimensional model. In addition, using human mesenchymal stem cell-derived spheroids, it was clarified that the multicellular behavior in the spheroids was greatly changed by chemical differentiation supplements. Moreover, we established an optical clearing technique necessary for cell observation inside the 3D spheroids and further developed a custom-made image analysis pipeline in Python to quantitatively evaluate cell nucleus shape in the spheroids.
