The process begins with the aggregation and condensation of loose mesenchyme. Hospital for Special Surgery, Caspary Research Building, 5th Floor, 535 East 70th Street, New York, NY 10021, USA. The latter process requires extracellular matrix remodeling and vascularization controlled by mechanisms that are not understood completely. Verzijl N., DeGroot J., Thorpe S.R., Bank R.A., Shaw J.N., Lyons T.J., et al. 2005]. The generation of these stresses occurs as a coordinated response to mechanical loading and their biophysical nature has been previously reviewed (23, 25). Int J Mol Sci. Epub 2005 May 23. The composition and cellular organization of human adult articular cartilage is complex with qualitative and quantitative differences in matrix constituents between the interterritorial region containing the collagen network of collagens II, IX, and XI and the pericellular matrix, containing collagen VI, fibromodulin, and matrilin 3, but little or no type II collagen. (2004), The surface of articular cartilage contains a progenitor cell population, Dreier R., Opolka A., Grifka J., Bruckner P., Grassel S.

Bosnakovski D, Mizuno M, Kim G, Takagi S, Okumura M, Fujinaga T. Biotechnol Bioeng. official website and that any information you provide is encrypted We and other investigators have found that there are common mediators of these processes in human OA cartilage. A recent study in murine OA models demonstrated that C5- and C6-deficient mice are partially protected from the development of OA [Wang et al. It has been additionally shown that BMP-4 and type IA BMP receptor proteins are overexpressed in cultured lymphocytes from FOP patients (82). Chondrogenesis and endochondral ossification are the cartilage differentiation processes that lead to skeletal formation and growth in the developing vertebrate as well as skeletal repair in the adult. MMP-1, -3 and -13 and cathepsins B and S, as well as IL-6, can be detected in OA synovial fluid samples, although at significantly lower levels than in patients with RA [Pozgan et al. The mechanisms underlying the initiation of chondrocyte progenitor proliferation and differentiation at the time of fracture injury are not well understood, although it has been suggested that mechanical stability and the early inflammatory response play key roles (49). (1977), The vascularity and remodelling of subchondrial bone and calcified cartilage in adult human femoral and humeral heads. It can be separated into two distinct layers: an outer layer that contains fibroblasts and distinct connections between the periosteum and bone, which are known as Sharpey fibers; and an inner layer known as cambium, which contains multipotent MSCs and osteoprogenitor cells that contribute to normal bone growth, healing, and regeneration (5254). Many chemokines are produced in joint tissues of patients with OA and after joint injury [Cuellar et al. 1997]. Thus, the transfection of SOX9 or all three SOX genes induced chondrogenesis and inhibited the osteogenesis of hMSCs. Vortkamp A., et al.

Gene profiling in experimental OA models has provided additional targets for consideration [Appleton et al. 2005]. Center for Musculoskeletal Research, University of Rochester Medical Center, Rochester, New York, USA. These changes allow the cell to respond rapidly to alterations in the environment, occurring through epigenetic modifications, including DNA methylation, histone modifications, and alterations in chromatin structure, and by microRNA-mediated mechanisms [Barter et al. The type of cartilage that is most prominent and most susceptible to both normal and pathologic forms of stress is the hyaline cartilage of the limb and trunk skeleton, which originates from the differentiation of condensed mesenchymal cells into clusters of cartilage cells known as chondrocytes. During the first few days following fracture, a hematoma is formed and this is followed by infiltration of inflammatory cells and release of growth factors, which direct the recruitment and proliferation of progenitor cells (Figure (Figure2).2). A summary of the influence of the most well-understood normal and pathologic stressors on the differentiation program is also presented. Expression and functional involvement of N-cadherin in embryonic limb chondrogenesis. (2010), MicroRNA-140 plays dual roles in both cartilage development and homeostasis, Moore E.E., Bendele A.M., Thompson D.L., Littau A., Waggie K.S., Reardon B., et al. In 1999 US chemists created an artificial liquid cartilage for use in repairing torn tissue. In the context of chondrocyte sensing of mechano-electrochemical events (discussed above), substantial effort has been spent trying to elucidate the key signaling mechanisms facilitating the cellular effects of loading. It involves progenitor cell specification, cell migration, epithelial-to-mesenchymal transition, and differentiation and maturation of chondrocytes. Efficacy of one-stage cartilage repair using allogeneic mesenchymal stromal cells and autologous chondron transplantation (IMPACT) compared to nonsurgical treatment for focal articular cartilage lesions of the knee: study protocol for a crossover randomized controlled trial. But their expression and activation change in response to mechanical or inflammatory stimuli. Thus, although Pb stimulates chondrogenesis, it reduces chondrocyte maturation and thereby results in delayed endochondral bone formation, as has been previously documented (112). 2009; Endres et al. This is why much attention has been paid to studying the cellular and molecular mechanisms that regulate chondrogenesis and chondrocyte differentiation. Huser C.A., Davies M.E. Schaller M.D., Otey C.A., Hildebrand J.D., Parsons J.T. FOIA We induced chondrogenic differentiation using Promocell's MSC chondrogenic differentiation medium and imaged how cells respond 7, 9 and 10 days after medium addition.

These findings help define the molecular markers of chondrogenesis and more accurately delineate the stages of chondrogenesis during chondrocytic differentiation of human MSCs. Strategies for studying mechanisms of osteoarthritis. The luciferase assay confirmed the circNFIX binding to miR7583p (Figure 3E). ALK2 functions as a BMP type I receptor and induces Indian hedgehog in chondrocytes during skeletal development. MeSH The relative temporal aspects of five stages of chondrogenesis are denoted by cellular, extracellular and molecular events: (1) Condensation of differentiated ESCs, (2) Differentiation into chondrocytes and fibril scaffold formation, (3) ECM deposition and cartilage formation, (4) Hypertrophy and degradation of cartilage, and (5) Bone replacement. Obesity and osteoarthritis: more complex than predicted! Although these results pertain to tendon insertion and/or attachment, it seems plausible to imagine that a similar dysregulation of AC development and/or growth can occur in joints that experience abnormal mechanical loading. Innate immune system activation in osteoarthritis: is osteoarthritis a chronic wound? This site needs JavaScript to work properly. Matrix remodeling involving matrix metalloproteinase (MMP) 9, 13, and 14 and vascularization mediated by vascular endothelial growth factor (VEGF) and VEGF receptors are required to convert the nonvascularized and hypoxic tissue to bone through the actions of osteoclasts and osteoblasts. These studies suggest that low-grade synovitis reflects preclinical disease during the early post-traumatic phase and could impact on the long-term outcome [Lotz and Kraus, 2010]. Conclusion: demonstrated that elimination of BMP-2 in the mouse limb disrupted the initiation of postnatal fracture healing (61), indicating an essential role for BMP-2 in bone repair and healing.

Retroviral delivery of Noggin inhibits the formation of heterotopic ossification induced by BMP-4, demineralized bone matrix, and trauma in an animal model. Correlating with this, mice exposed to Pb with blood Pb levels mimicking the established childhood toxicity range have accelerated and increased chondrogenesis in muscles implanted with BMP-2expressing C9 cells (111). Conclusion These findings help define the molecular markers of chondrogenesis and more accurately delineate the stages of chondrogenesis during chondrocytic differentiation of human MSCs. Similar effects of rofecoxib and indomethacin on the incidence of heterotopic ossification after hip arthroplasty. Chondrogenesis is a tightly regulated multistep process, including mesenchymal cell recruitment/migration, prechondrogenic condensation of the mesenchymal cells, commitment to the chondrogenic lineage, and differentiation into chondrocytes.

Chondrocyte hypertrophy and osteoarthritis: role in initiation and progression of cartilage degeneration? A novel murine segmental femoral graft model. These cells differentiate, hypertrophy, undergo apoptosis, and are replaced by invading vasculature and osteoblasts, creating the secondary center of ossification (labeled 2 in Figure Figure1).1).

Smoking delays chondrogenesis in a mouse model of closed tibial fracture healing. [citation needed], Adult hyaline articular cartilage is progressively mineralized at the junction between cartilage and bone. Only the most terminally differentiated hypertrophic chondrocytes express the matrix degrading enzyme Mmp13 (18). Both positive and negative signaling kinases and transcription factors, such as Sox9 and Runx2, and interactions among them determine whether the differentiated chondrocytes remain within cartilage elements in articular joints or undergo hypertrophic maturation prior to ossification. 2009]. Ectopic bone formation develops through a cartilage intermediate, so the initial events of heterotopic ossification require chondrogenesis. government site. Specific microRNAs (miRNAs) have been linked to alterations in gene expression in human OA [Iliopoulos et al.

Differential effect of BMP4 on NIH/3T3 and C2C12 cells: implications for endochondral bone formation. doi: 10.1016/j.injury.2008.01.038. The association of DDR2, MMP-13, and MMP-specific type II collagen cleavage fragments cannot only be observed in the Col9a1/ and Col11a1+/ mice, but also in wild type mice subjected to destabilization of the medial meniscus (DMM) surgery and in human OA cartilage [Xu et al. The chondrogenic process of committed MSCs was initiated with highly activated chondrogenic adhesion molecules and stimulated cartilage developmental growth factors, including members of the transforming growth factor beta superfamily and their downstream regulators, the Smads, as well as endothelial growth factor, fibroblast growth factor, insulin-like growth factor, and vascular endothelial growth factor. Defects occur at various stages of healing, including during chondrogenesis and chondrocyte differentiation. Understanding how the subtle application of normal mechanical stress leads to appropriate limb and cartilage development is important for envisioning therapies that facilitate cartilage repair, including tissue engineering approaches. Those synthetic groups are very similar to the lipids found in cell membranes. De La Pena L.S., et al. Severe inactivity can produce analogous catabolic effects, including reduced cartilage thickness and proteoglycan loss (27). Arikawa T., Omura K., Morita I. 2011], although clinical trials have not gone forward. Guilak F., et al. SOST is normally expressed by osteocytes, but a recent study showed upregulated expression of SOST by OA chondrocytes in regions of cartilage damage, but decreased expression in regions of subchondral bone sclerosis [Chan et al. 2010]. Scientific Developments and Clinical Applications Utilizing Chondrons and Chondrocytes with Matrix for Cartilage Repair. Disruption of these pathways may induce chondrocytes to recapitulate a developmental molecular program, including expression of markers of chondrocyte hypertrophy such as COL10A1, MMP-13, and Runx2. Osteoarthritis is characterized by an imbalance in cartilage homeostasis, which could potentially be corrected by mesenchymal stem cell (MSC)-based therapies. Achondrogenesis type 1B, also known as the Parenti-Fraccaro type, is characterized by extremely short limbs, a narrow chest, and a prominent, rounded abdomen. 2008], as well as by MMP-13 itself [Borz et al. (2010), Treatment of murine osteoarthritis with TrkAd5 reveals a pivotal role for nerve growth factor in non-inflammatory joint pain, Melrose J., Fuller E.S., Roughley P.J., Smith M.M., Kerr B., Hughes C.E., et al. 2010]. Inflammatory cytokines may also induce chemokines, including IL-8, and other cytokines such as IL-6, leukemia inhibitory factor, IL-17, and IL-18. Although these heavy metals clearly regulate chondrogenesis, little is known about the molecular mechanisms underlying the toxicity in mesenchymal populations that leads to impaired cartilage formation.

Hypoxia in cartilage: HIF-1alpha is essential for chondrocyte growth arrest and survival. This is partly because more effective biomarker analyses and imaging strategies need to be applied to stratify patients according to criteria that are likely to show structure modification and differentiate the pain response [Kraus et al. Important markers at each stage of chondrocyte differentiation are listed below the stage at which the genes are expressed. As these cells proliferate and undergo the early steps of maturation, they flatten and form columns parallel to the axis of longitudinal growth. Vortkamp A., et al. Nemoto K., et al. Molofsky A.V., Pardal R., Morrison S.J. One conceivable explanation for FOP is that MSCs in the area surrounding a future site of heterotopic bone are not prone to differentiate into bone-forming osteogenic cells under normal conditions but that mutations in ACVR1 in these tissues trigger mesenchymal cells to differentiate into cells that support heterotopic endochondral ossification. Methods: A coculture preconditioning system was used to improve the chondrogenic potential of human MSCs and to study the detailed stages of chondrogenesis of MSCs, using a human MSC line, Kp-hMSC, in commitment cocultures with a human chondrocyte line, hPi (labeled with green fluorescent protein [GFP]). Tumor necrosis factor alpha (TNF-alpha) coordinately regulates the expression of specific matrix metalloproteinases (MMPS) and angiogenic factors during fracture healing. Lehmann W., et al. (2007b), Crucial role of macrophages in matrix metalloproteinase-mediated cartilage destruction during experimental osteoarthritis: involvement of matrix metalloproteinase 3, Bondeson J., Blom A.B., Wainwright S., Hughes C., Caterson B., van den Berg W.B. This substantially hampers efforts to track the fate of these cells in repair and further understand the cellular and molecular mechanism(s) pertaining to the activation of this important progenitor cell pool. Under normal, low turnover conditions, chondrocytes are resting in a nonstressed steady state and maintain synthesis of proteoglycans and other noncollagen molecules [Maroudas et al. 2006]. A major challenge to efforts to repair cartilage by stem cell-based and other tissue-engineering strategies is the inability of the resident chondrocytes to lay down a new matrix with the same properties as it had when it was formed during development. In addition, levels of exposure to Pb during childhood are inversely correlated with final height, weight, and chest circumference (108110). However, aggrecan depletion, by itself, does not drive OA progression, as suggested by recent studies in Mmp13 knockout mice showing that MMP-13 deficiency inhibits cartilage erosion, but not aggrecan depletion [Little et al. 19, 20). chondrogenic markers such as matrilin 4 ( matn4 ), aggrecan ( acan ), collagen type vi alpha 3 chains ( col6a3 ), collagen type ix alpha 1 chain ( col9a1 ), and sry-box 6 and 9 ( sox6 and sox9) were upregulated as early as at day 7 (d7), while the expression of collagen type ii alpha 1 chain ( col2a1) was increased at d21 (fig. 2009] with an inhibitor of LXR [Li et al. Molecular aspects of healing in stabilized and non-stabilized fractures. Birth Defects Res C Embryo Today. Altered aggrecan synthesis correlates with cell and nucleus structure in statically compressed cartilage. Chondrogenesis is the earliest phase of skeletal development, involving mesenchymal cell recruitment and migration, condensation of progenitors, and chondrocyte differentiation, and maturation and resulting in the formation of cartilage and bone during endochondral ossification. Fetal and infant lead exposure: effects on growth in stature. Interleukin (IL)-1, toll-like receptor (TLR) ligand, reactive oxygen species (ROS), advanced glycation endproducts (AGEs) interact with the cell through distinct receptors that transduce phosphorylation events via cytoplasmic interactions initiating various protein kinase cascades.

In particular, endochondral bone formation, which is the focus of this Review, always takes place close to where the junction between the broken bone ends will develop. When chondrogenesis and chondrocyte maturation occur in the adult, such as during fracture repair, no secondary centers of ossification are formed, nor is a novel limb generated, but the processes progress essentially the same way and hypertrophic chondrocytes are ultimately required for analogous purposes the initiation of mineralization and the induction of vascular invasion. In the context of endochondral ossification (and possibly in chondrocytes that are undergoing inappropriate hypertrophy during OA), ROS are increased as the cells differentiate (100).

Periosteal progenitor cell fate in segmental cortical bone graft transplantations: implications for functional tissue engineering. Saudan M., et al. Cartilage-specific -catenin signaling regulates chondrocyte maturation, generation of ossification centers, and perichondrial bone formation during skeletal development. Although animals and humans have only very limited capacity to regenerate damaged tissues, it has long been suspected that postnatal bone repair, such as fracture healing, recapitulates some of the essential pathways in limb development, although the fracture repair process is not capable of supporting limb regeneration per se. Recent reports also demonstrate that BMP-2 stimulates Osx mRNA expression and AP activity in ST2 pluripotent stromal cells, and these effects are enhanced by the selective EP4 receptor agonist ONO-4819 (77). 2010]. Indian hedgehog signaling regulates proliferation and differentiation of chondrocytes and is essential for bone formation. Alterations in joint mechanics that are caused by injury to cartilage or surrounding structures (such as the shock-absorbing meniscus in the knee) would presumably also lead to this type of cartilage catabolism. 2009], but there is an increase in the cells expressing the mesenchymal progenitor cell markers, Stro1 and Notch1, in the chondrocyte clusters appearing during OA [Grogan et al.

Since the chondrocytes in adult human cartilage are normally quiescent and maintain the matrix in a low turnover state, understanding how they undergo phenotypic modulation and promote matrix destruction and abnormal repair in OA may to lead to identification of critical targets for therapy to block cartilage damage and promote effective cartilage repair. In fact, MAPK signaling with downstream activation of the MEK-Erk1 signaling pathway leads to downregulation of Agc gene expression in bovine articular chondrocytes (35). Chondrocytes in the superficial zone uniquely produce lubricin, or superficial zone protein, a splice form of PRG4.

Thus, COX-2 induction of PGE2 production and signaling through PKA in muscle stem cells is a possible link between the inflammatory response to injury and ectopic bone formation. 2010]. Tomita M., Reinhold M.I., Molkentin J.D., Naski M.C. [5], Bone morphogenetic proteins are growth factors released during embryonic development to induce condensation and determination of cells, during chondrogenesis. Oxygen is required for normal cellular metabolism, and oxygen deficiency within cartilage tissues can induce an hypoxic state that affects chondrocyte function. Following fracture or osteotomy, progenitor cells residing in the periosteum are activated and enter the cell cycle (ii), followed by differentiation into osteoblastic and chondrogenic (green) lineage cells (iii). 2009]. will also be available for a limited time. Following chondrogenesis, the chondrocytes remain as resting cells to form the articular cartilage or undergo proliferation, terminal differentiation to chondrocyte hypertrophy, and apoptosis in a process termed endochondral ossification, whereby the hypertrophic cartilage is replaced by bone. 2008; Jones et al. 2011; Haglund et al.

Long-term self-renewal of postnatal muscle-derived stem cells. These processes are subject to complex regulation by interplay of the fibroblast growth factor (FGF), transforming growth factor (TGF), bone morphogenetic protein (BMP) and Wnt signaling pathways [Haque et al. 2009].
