Hypertrophic differentiation is not only the terminal process of endochondral ossification in the growth plate but is also an important pathological change in osteoarthritic cartilage. Collagen type II COL2A1 was previously considered to be only a structural component of the cartilage matrix, but recently, it has been revealed to be an extracellular signaling molecule that can significantly suppress chondrocyte hypertrophy.

Authors Ahmed Nahian 1 ; Amit Sapra 2. The cartilage is solely composed of cells known as chondrocytes. Chondrocytes maintain the extracellular matrix ECM and produce the cartilage matrix. Surrounded by collagenous fibers, chondrocytes release substances to make cartilage strong yet flexible. In general, chondrocytes are found within intervertebral discs and in any form of articular cartilage AC. Chondrocytes play a crucial role in maintaining homeostasis within the AC joints that provide cushioning in joint movements.

The neonatal mice with homozygous Hbb deletion died within 1—7 days after birth, chondrocyte the heterozygous Hbb mice survived to adulthood and were fertile Supplementary Fig. Similar articles in PubMed, chondrocyte. The total protein in the samples was estimated on a Coomassie Blue-stained SDS gel according to a standard chondrocyte marker with known concentration.

The majority of its structure and function is controlled by chondrocytes that regulate Extracellular Matrix ECM turnover and maintain tissue homeostasis. Imbalance in their function leads to degenerative diseases like Osteoarthritis OA. OA is characterized by cartilage degradation, osteophyte formation and stiffening of joints.

Chondrocyte

Chondrocytes are the cells making up the cartilage. They are pivotal to synthesize cartilage matrix and sustain the extracellular matrix. It primarily comprises the proteoglycans and collagen. Chondrocytes are surrounded by the collagenous fibres and secrete substances causing the cartilage to acquire strength and flexibility.

After polymerization, cartilaginous tissues were trimmed under a stereomicroscope and mounted onto blank resin stubs. Source data Source Data Fig. Revised : 01 December However, the regulation of these remains to be elucidated. Values are reported as ratios relative to pre-bleaching time points. Thus, our findings provide new insight into the regulation of cartilaginous phenotype and OA progression. Thus, the eosin-positive structure might be a common feature of chondrocytes irrespective of the source and species. Endochondral ossification is crucial for skeletal development, specifically in preexisting cartilaginous models. The results showed that even partial deletion of either Hba or Hbb sensitized chondrocytes to death induced by hypoxia in the cartilage growth plates Fig. They inherently contain low mitochondrial numbers [ 2 ]. Current research aims to utilize cell-based therapies to reverse cartilage loss. Talukdar, M. Articular cartilage and changes in arthritis.

Timelapse imaging Cells were grown on a mm glass bottom dish Nest and images were taken with the Ultraview Vox confocal system Volocity 6. This low density is due to the high matrix to cell volume ratio [ 7 , 8 ]. Archived from the original on October 6, Type II collagen degradation and its regulation in articular cartilage in osteoarthritis. For each mouse, the humerus or femurs were used for culture in vitro. Aho, O. MSCs were isolated and purified from bone marrow obtained from healthy volunteer donors using density-gradient centrifugation, as described previously. The role of HIF proteins in maintaining the metabolic health of the intervertebral disc Article 03 June Hypertrophic differentiation of chondrocytes in osteoarthritis: the developmental aspect of degenerative joint disorders. Moreover, cellular attempts to repair the tissue results in aberrant osteoblast like differentiation forming osteophytes or fibroblastic differentiation inducing fibrosis or stiffening of the joints [ 38 — 40 ]. Incorrect signals are sent to chondrocytes in the cartilage anlage because the GAG chain and proteoglycan complexes are unable to work properly and cause the chondrocytes to mature and ossify too quickly. Therefore, these results support that KLF1 could mediate hypoxia-induced Hba and Hbb expression in chondrocytes. Ossification primary bone intramembranous endochondral.
