Obviously, MGP is responsible for disrupting bone formation and inhibiting mineralization. doi: 10.1016/j.biomaterials.2014.10.012, Polo-Corrales, L., Latorre-Esteves, M., Ramirez-Vick, J. E. (2014). It is composed of specific proteins and polysaccharides. A review of fibrin and fibrin composites for bone tissue engineering. Therefore, ECs in OMSC/EC‐scaffold plays an important role in bone formation and vascularization (Li et al., 2019). Collagen type I degradation fragments act through the collagen receptor LAIR-1 to provide a negative feedback for osteoclast formation. These results suggest that, unlike TSP1, TSP2 may act as an inhibitor of MSCs proliferation and a promoter of differentiation by regulating the mechanism of collagen fibrillogenesis. Tissue Eng. ECM itself or modified with biomaterial-based scaffold is used in biological scaffolds to mimic the natural biomaterials. Arch. The matrix has organic (collagens, mainly type 1) and inorganic (calcium phosphate, osteocalcium phosphate) constituents . Osteoclasts secrete osteopontin into resorption lacunae during bone resorption. Acta Biomater. Stem Cells Int. B., Santiago-Junior, J. F., Okamoto, R. (2018). doi: 10.1166/jnn.2014.9127, Ramesh, N., Moratti, S. C., Dias, G. J. 54, 275–282. (2018). Received: 19 December 2019; Accepted: 06 May 2020;Published: 26 May 2020. The manufacture of superior tissue-engineering constructs depends on three basic elements: appropriate scaffolds to support tissue-cell regeneration, cytokines, and appropriate seed cells. Because they can better simulate the composition, distribution, and biochemical signals of various matrix components in native bone tissue, they can emulate the natural bone microenvironment. J. Nanosci. Cell Bio 15, 786–801. doi: 10.1016/j.bone.2010.02.011, Hinsenkamp, M., Muylle, L., Eastlund, T., Fehily, D., Noel, L., Strong, D. M. (2012). Int. doi: 10.1007/s00418-019-01770-y, Mansour, A., Mezour, M. A., Badran, Z., Tamimi, F. (2017). doi: 10.1002/jbm.b.32648, Alford, A. I., Terkhorn, S. P., Reddy, A. (2013). The levels of DMP1 and Sclerostin are greatly increased on collagen-based substrates with low stiffness, indicating enhanced osteocyte differentiation compared to ECM substrates with high stiffness (Mullen et al., 2013). Although embedded in the bone matrix, osteocytes form contacts with each other and with bone lining cells, which aid bone growth and repair. The formation and activity of osteoclasts activated by macrophage colony-stimulating factor (M-CSF) and receptor for activation of nuclear factor κB (NF-κB) ligand (RANKL), which are derived from osteoblasts (Lin et al., 2019). Osteocytes are the terminally differentiated immobilized cells in the bone matrix. (1991). doi: 10.1590/1678-7757-2016-0531, Finkelman, R. D., Butler, W. T. (1985). doi: 10.1359/jbmr.2000.15.5.851, Hesse, E., Kluge, G., Atfi, A., Correa, D., Haasper, C., Berding, G., et al. The extracellular matrix of cartilage and bone is secreted by specialized cells derived from fibroblasts: chondroblasts for cartilage; osteoblasts for bone. Deficiency of TSP2 inhibits the differentiation of primary MSCs into osteoblasts, accompanied by decreased matrix collagen content and disrupted type I collagen assemble process (Alford et al., 2013). Adv. With the development of 3D printing technology in recent years, the ECM can be processed through biological printing to obtain scaffolds with various topology, such as porous and lamellar, or even scaffolds with a shape that exactly matches the defect site. 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. The extracellular matrix is comprised of non-cellular components within tissues that form an essential scaffold for cellular constituents. 7, 211. doi: 10.3389/fbioe.2019.00211, Moorehead, C., Prudnikova, K., Marcolongo, M. (2019). Composite Scaffolds of Mineralized Natural Extracellular Matrix on True Bone Ceramic Induce Bone Regeneration Through Smad1/5/8 and ERK1/2 Pathways (vol 24, pg 502, 2018). Rickets may also cause slow physical growth, bowed legs, knock knees and widening wrists. In the future, further studies on the cellular and molecular mechanisms the mediate the effects of the ECM on bone cells and bone repair will contribute to the further development of ECM-based scaffolds in bone tissue engineering. Thrombospondins (TSPs), which are classified as TSP1 through TSP5, are present in developing skeleton and bone and is expressed by osteoblasts. Front. doi: 10.3109/03008207.2010.546536, Jani, P. H., Gibson, M. P., Liu, C., Zhang, H., Wang, X., Lu, Y., et al. (2000) demonstrates that osteonectin-null mice had lower total collagen I content, bone mineral density and numbers of osteoblasts and osteoclasts in bone, and exhibited reduced biomechanical properties. Osteonectin is a vital regulator of the calcium release by binding collagen and HA crystals, thereby influencing the mineralization of collagen during bone formation (Rosset and Bradshaw, 2016). Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. J. BioMed. (2016). The multiple facets of periostin in bone metabolism. Cell Biol. Bone Res. BMSCs are capable of migration, proliferation, differentiation, and cell-cell communication. 26, e20160531. Age dependent regulation of bone-mass and renal function by the MEPE ASARM-motif.

Extracellular matrix is the extracellular, complex mixture of various biomolecules and fibers secreted by cells in the tissues of multicellular organisms. doi: 10.1007/s40279-013-0100-7, Frantz, C., Stewart, K. M., Weaver, V. M. (2010). J. Int. In contrast, MGP suppresses the nuclear translocation of NFATc1 and intracellular Ca2+ flux in osteoclasts, which in turns attenuate the differentiation and bone resorption. Osteoblasts require a surface to synthesize new matrix, which is provided by collagen. Mater. 78, 1246–1262. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? The RGD sequence of OPN and BSP interact with αvβ3 integrin initiate osteoclast adhesion to bone matrix and formation of actin ring of polarized osteoclasts, which is crucial for bone development. Mice lacking DMP1 show severe bone defects, displaying increased serum fibroblast growth factor 23 (FGF23) and decreased serum phosphorus, as well as deformed and low-mineralized bone (Jani et al., 2016). Prog. Like BSP, OPN is a major regulator of bone formation, mineralization, especially in bone turnover. DMP1 prevents osteocyte alterations, FGF23 elevation and left ventricular hypertrophy in mice with chronic kidney disease. In this review, we briefly introduce the inorganic and organic ECM of bone tissue (Table 1), including collagenous and non-collagenous proteins, and summarize the effects of the ECM on osteoblast-lineage cells, including MSCs, osteoblasts, and osteocytes, and osteoclasts. Biomaterials 37, 230–241. (2016). 11, 571–587. (Liu et al., 2016). This approach relies on bone tissue harvested from a patient's own donor site, which is transplanted into the same patient's damaged area. Rev. 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.
