In bone, for example, a mineralized extracellular matrix … Therefore, SLRPs play an essential role to maintain bone homeostasis. J. Dent. Compared to untreated defects, the scaffolds containing DPSCs significantly promoted the formation of correctly structured new bone and increased the volume of fibrous connective tissue and mineralized tissue, which was accompanied by the increased expression of osteogenic ALP and type I collagen (Chamieh et al., 2016). 423, 53–59. Accelerated craniofacial bone regeneration through dense collagen gel scaffolds seeded with dental pulp stem cells. J. Dent. In addition, biglycan-KO mice show the low activity of alkaline phosphatase (ALP)-positive MSCs, possibly due to apoptosis, which leads to a decrease of proliferation (Chen et al., 2002). 2020 Jul;13(7):100789. doi: 10.1016/j.tranon.2020.100789. Rickets is a bone disorder in which bones soften, break easily and become … The extracellular matrix of bone A. is entirely composed of proteoglycans. Osteoclasts, are multinucleated cells formed from the fusion and differentiation of monocyte/macrophage precursors, involve in bone resorption. Co 501, 968–973. C-Mater. OCN is specifically expressed by bone-forming osteoblasts and contains three Gla residues, which give OCN the ability to bind calcium to modulate calcium metabolism by mediating its association with hydroxyapatite. While additives can enhance the bone regeneration ability of the defect site, they must not affect the growth of other adjacent tissues at the graft site, hence avoiding inflammation and hyperplasia. Because the grafts contain the native bone matrix, osteoblasts, and growth factors, they intrinsically possess osteoinductivity and osteoconductivity (Garcia-Gareta et al., 2015). Cytotechnology 10, 187–188. Common ECM-modified scaffold designs use a single or a combination of components of the ECM or apply a coating combined with biomaterials to produce scaffolds. doi: 10.1016/j.bone.2018.12.001, Calori, G. M., Tagliabue, L., Gala, L., d'Imporzano, M., Peretti, G., Albisetti, W. (2008). The manufacture of superior tissue-engineering constructs depends on three basic elements: appropriate scaffolds to support tissue-cell regeneration, cytokines, and appropriate seed cells. On account of the synergistic effect of stem cells and ECM, the stem cells/ECM composite scaffolds are more conducive to bone remodeling than ECM modified scaffolds. (2017). (2017). 6, 24. doi: 10.1038/s41413-018-0026-7, Kram, V., Kilts, T. M., Bhattacharyya, N., Li, L., Young, M. F. (2017). components of the extracellular matrix.

When a dECM derived from MG63 cells was deposited on a CS/PCL scaffold, hMSCs exhibited enhanced attachment, proliferation, and osteogenic differentiation, and the scaffold showed anti-inflammatory features in vitro. (2019). Osteocalcin null mice show larger HA crystal size, suggesting that osteocalcin may regulate the maturation rate of minerals (Zoch et al., 2016). doi: 10.1016/j.tibtech.2012.07.005, Boudiffa, M., Wade-Gueye, N. M., Guignandon, A., Vanden-Bossche, A., Sabido, O., Aubin, J. E., et al. The ideal scaffold should also promote the attachment, increase the viability and proliferation, as well as induce osteogenic differentiation and angiogenesis. (Lausanne) 10, 891. doi: 10.3389/fendo.2019.00891, Zhang, Y., Zhao, L., Wang, N., Li, J., He, F., Li, X., et al. Moreover, the GHA-MFE fiber scaffolds significantly increased the rate of new bone formation in rabbit femoral cortical bone defect after 4 weeks of implantation compared with commercial Surgiwear™ (Shamaz et al., 2015). Res. However, this approach is limited by the available sources of grafts and secondary damage at the donor site.

(B) decellularized ECM scaffold obtained either from tissue in vivo or cultured cells in vitro by decellularization, which is a promising strategy to induce bone regeneration and has good clinical performance. Further development of 3D printing technology in ECM-based scaffolds is beneficial to the field of bone tissue engineering and regenerative medicine. J. Bone 81, 112–121. Int. doi: 10.1074/jbc.M500573200, Bonnans, C., Chou, J., Werb, Z. Clipboard, Search History, and several other advanced features are temporarily unavailable. In bone remodeling, OPN regulates osteoclastogenesis and osteoclast activity, which contributes to bone formation and resorption (Singh et al., 2018). Changes in the overall formation rate of the canalicular network increase osteoblast activity and bone formation. Tissue-engineering strategies rely on three basic elements—seed cells, scaffolds, and cytokines—which interact to produce engineered tissue constructs (Hu, 1992). Circulating OCN not only acts as a hormone that regulates glucose and energy metabolism, but its concentration in serum can be used as a biochemical indicator of bone formation (Mizokami et al., 2017). Collagen plays an important role in determining bone strength. (2013). Consequently, HA is widely used for coatings on metallic implants, bone fillings, and injectable bone substitutes (Ramesh et al., 2018). The osteoclast has multiple nuclei (blue arrows) and stained tartrate resistant acid phosphatase (TRAP) positive, indicative of a mature osteoclast. J. Integrative Analysis of Periostin in Primary and Advanced Prostate Cancer. Moreover, periostin can also affect osteoblast differentiation and bone formation, suggesting that periostin is involved in bone anabolism by regulating Wnt/β‐catenin signaling (Merle and Garnero, 2012) (Table 3). (2004). Because multicellularity evolved independently in different multicellular lineages, the composition of ECM varies between multicellular structures; however, cell adhesion, cell-to-cell communication and differentiation are common functions of the ECM. 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. 23, 1199–1212. doi: 10.1016/j.matbio.2015.12.001, Kaipatur, N.

Thrombospondin-1 inhibits osteogenic differentiation of human mesenchymal stem cells through latent TGF-beta activation. 3 The extracellular matrix of bone consists of a. collagen fibers. Whereby the efficiency of attachment between hMSCs and the PCL/HA scaffold was improved with a higher HA content of 5% to 10% and in a HA concentration-dependent manner (Kumar et al., 2017). B., et al. Biomimetic extracellular matrix-incorporated scaffold induces osteogenic gene expression in human marrow stromal cells. During bone formation, SLRPs participate in all stages including cell proliferation, osteogenesis, mineral deposition, and bone remodeling (Kirby and Young, 2018). MGP-deficient mice have reportedly exhibited premature bone mineralization, while mice with MGP overexpression in osteoblasts showed reduced mineralization of intramembranous bone and hypomineralized tooth dentin and cementum (Luo et al., 1997; Kaipatur et al., 2008). Z., Xu, G. W., et al. 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). Use of eggshell-derived nano-hydroxyapatite as novel bone graft substitute-A randomized controlled clinical study. 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. Dental pulp stem cells and Bonelike((R)) for bone regeneration in ovine model. Thus, BSP is vital in the regulation of osteoblast differentiation and initiation of matrix mineralization in bone tissue (Marinovich et al., 2016). Cancer 8, 212–226. It has been reported that periostin may interact directly with sclerostin and promotes Wnt signaling inhibited by sclerostin (Bonnet et al., 2016). The collagen type I, III, and V are the most abundant constituents of the organic ECM in bones. Cell Rep. 21, 2585–2596.
