In mice, deletion of TSP2 results in increased number and proliferation ability of MSC, and also characterized by delayed osteogenesis and increased adipogenesis (Hankenson et al., 2000). In mice, global knockout of TSP-1, -3, and -5 can cause severe abnormalities in skeletal development (Delany and Hankenson, 2009).

Except for OCN and MGP, periostin is another abundantly expressed Gla-containing protein in bone. (2017). 106, 2046–2057. Small leucine-rich proteoglycans (SLRPs), such as biglycan, decorin, keratocan, and asporin, are important proteoglycans family in the bone. MGP also inhibits bone formation and MGP-null mice exhibit an osteopenic phenotype, suggesting that MGP plays a stronger role in bone absorption than in bone formation (Zhang Y. et al., 2019). Mechanical loading stimulates dentin matrix protein 1 (DMP1) expression in osteocytes in vivo. Orthop. (2017). J. The lack of type I collagen or mutation of collagen structure results in changes in the ECM, and thus significantly increases fracture risk (Fonseca et al., 2014). Cell-derived dECM, rich in collagen, matrix macromolecules, and growth factors, has good biocompatibility and biodegradability, making it beneficial for the proliferation and osteogenic differentiation of MSCs, and can be used as cell culture matrix for bone regeneration medicine.

I., Gu, X. S. (2017). Glycoproteins contain covalently attached carbohydrate molecules on the protein chain in various combinations and positions. Therefore, the components and composition of decellularized ECM scaffolds, as well as the dynamic changes of ECM under different culture conditions should be further studied to make it more similar to the natural ECM composition. MSCs, osteoblasts, and osteocytes sense mechanical and biochemical signals from the ECM and respond to these signals by regulating their fate (Assis-Ribas et al., 2018). Additionally, it is difficult to precisely control the ECM components secreted by cells, so that they can be standardized and unified in mass production. Cold Spring Harb. Recently, it is demonstrated that the process by which osteocytes push type I collagen fibers outward from the center of the formed lacuna mediates osteocytes lacunae formation, which is accompanied by increased collagen deposition and collagen-fiber network compaction surround the lacunae. Other ECM molecules, such as OPN, OCN, and DMP1, can regulate the proliferation of MSCs and osteogenesis. doi: 10.1590/1678-7757-2016-0531, Finkelman, R. D., Butler, W. T. (1985).

It has long been understood to be the structural support for cells since its characteristics set the characteristics of the … The main function of collagens is mechanical support and to act as a scaffold for bone cells (Saito and Marumo, 2015). Even when using decellularized preparations of autologous or allogeneic tissue or cells cultured in vitro, the integrity and mechanical properties of the matrix components are preserved, while achieving low immunogenicity by removing cell-bound antigens. B. Ornamenting 3D printed scaffolds with cell-laid extracellular matrix for bone tissue regeneration. J. Dent. Notably, the addition of BMP-2 led to almost complete healing of bone defects (Kim et al., 2015). 2015;65:20–31. Like cartilage, and other types of connective tissue, bone is made up of Cells and Extracellular matrix: Cells - which in bone are called osteoblasts and osteocytes, (osteo - bone). 36, 69–80. A better understanding of the role of bone ECM in guiding cellular behavior and tissue function is essential for its future applications in bone repair and regenerative medicine. (Liu et al., 2016). Knockout of MEPE in mice increases bone mass and trabecular density and shows abnormal cancellous bone. Cancer Metastases to Bone: Concepts, Mechanisms, and Interactions with Bone Osteoblasts.

Tissue engineering utilizes the basic principles and methods of life sciences and engineering to create functional tissue substitutes in vitro, which can be used to repair tissue defects and replace the partial or total loss of organ function (Shafiee and Atala, 2017). Endocrinol. These fibrils interact with other collagenous and noncollagenous proteins to assemble the higher-order fibril bundles and fibers (Varma et al., 2016). Moreover, MEPE interacts with DMP1 and PHEX to affect FGF23 expression, thereby regulating phosphate, mineralization, and bone turnover (Zelenchuk et al., 2015). Once osteoclastogenesis is initiated, mono-nucleate osteoclast precursors fuse together to form multi-nucleate, mature osteoclasts.

This means that native decellularized bone transplantation has a broad application prospect in orthopedic surgery. It is mainly synthesized by osteoblasts before the mineralization process (Mansour et al., 2017). Moreover, they can synthesize copious amounts of extracellular matrix proteins such as collagen type IIIα1 and Vα1, α5 and β5 integrin chains, fibronectin, connective tissue growth factor, and transforming growth factor beta I (TGFβI) (Ren et al., 2011). BSP can promote bone resorption, and the migration of preosteoclast and mature osteoclasts is impaired in the absence of BSP (Boudiffa et al., 2010). Bone cells (osteoblasts, osteocytes and odontoblasts) are the major source of MEPE. doi: 10.1016/j.jtice.2009.10.002, Ueno, A., Miwa, Y., Miyoshi, K., Horiguchi, T., Inoue, H., Ruspita, I., et al. doi: 10.1111/cpr.12658, Lin, X., Zhao, C., Zhu, P., Chen, J., Yu, H., Cai, Y., et al. The stiffness of the surrounding matrix is one of the most important signals that regulate osteocyte behaviors, and changes in the stiffness of the ECM induce alterations in the cytoskeleton and cell morphology, as well as fibronectin, which leads to changes in paxillin and in turn affects the elongation of osteocyte gap junctions (Zhang D.

Above all, different types, proportions, structures of ECM, and even different implanted cells can all affect the bone regeneration performance of the ECM-modified biomaterial scaffold, suggesting that there may be a set of elements of ECM that work in concert to guide bone regeneration. J. Advances in understanding the interactions between the bone ECM and bone metastatic cancer cells are necessary in order to both regulate and prevent metastatic cancer cell growth in bone. (2017). Osteoporos. It is composed predominantly of collagens, non-collagenous glycoproteins, hyaluronan and proteoglycans.

Cell Biol. used dECM from porcine bone to form 3D-printed PCL/β-TCP/bone dECM scaffolds, which promoted more new bone regeneration 6 weeks after repair of a rabbit calvarial defect in vivo. BiologyWise provides an in-depth study of the components, structure, and function of extracellular matrix. (2019). (2010). Asporin competes with decorin for collagen binding, binds calcium and promotes osteoblast collagen mineralization.
