WebMar 23, 2016 · As a result, the downstream Runx2 and MEF2C were regulated by miR-365 and contribute to hypertrophic conversion of chondrocytes in OA cartilage. Hypertrophic maturation of chondrocytes is a crucial step in endochondral ossification, whereas abnormally accelerated differentiation of hypertrophic chondrocytes in articular cartilage … WebThis proliferation leads to hypertrophy (cells will take up fluids, increase in size) of chondrocytes and then secrete growth factors, most importantly Vascular Endothelial Cell Growth Factor What does Vascular Endothelial Cell Growth Factor induce?

WebMar 26, 2024 · During chondrogenesis, the mesenchymal cells become round and then flattened chondrocytes, followed by pre-hypertrophic and hypertrophic chondrocytes. The purpose of this phase is to organize into a columnar structure within a growth plate responsible for longitudinal growth. WebApr 10, 2024 · Hypertrophic chondrocytes located in different cartilage regions are exposed to an inappropriate stromal and endocrine/paracrine environment that is even less favorable for survival . We found that in the absence of DYRK1A, the expression of Col X and MMP13 was downregulated in articular chondrocytes, suggesting that the loss of DYRK1A leading ...
WebAug 25, 2008 · Chondrocytes in the mandibular condylar cartilage rapidly differentiate into hypertrophic chondrocytes (Shibata et al. 1997; Fukada et al. 1999; Fukuoka et al. 2007) and this rapid differentiation may account for the discrepancy relevant to Sox5 expression between condylar (secondary) cartilage and Meckel's (primary) cartilage. WebFeb 20, 2024 · At the edge of the hypertrophic zone, chondrocytes re-enter the cell cycle and express leptin receptor ( lepr ), suggesting conversion into progenitors. Further, mutation of matrix metalloproteinase 9 ( mmp9) results in delayed growth plate remodeling and fewer marrow adipocytes.
WebSep 16, 2024 · Consistent with the hypothesis, hypertrophic differentiation was inhibited and expression of the articular surface marker lubricin (Prg4) was dramatically induced when chondrocyte pellets were exposed to synovium- or synoviocyte-conditioned media, but not to chondrocyte- or osteoblast-conditioned media. WebOn the other hand, ectopic hypertrophy of articular chondrocytes has been implicated in the pathogenesis of osteoarthritis. Thus, a better understanding of the processes that control …
WebChondrocyte hypertrophic differentiation, a key process in endochondral ossification (EO), is also a feature of osteoarthritis leading to articular cartilage destruction. ShcA (Src homology and Collagen A) is an adaptor protein that binds to the
