Abstract
Mechanical inputs give rise to p38 and JNK activation, which mediate adaptive physiological responses in various tissues. In skeletal muscle, contraction‐induced p38 and JNK signaling ensure adaptation to exercise, muscle repair, and hypertrophy. However, the mechanisms by which muscle fibers sense mechanical load to activate this signaling have remained elusive. Here, we show that the upstream MAP3K ZAKβ is activated by cellular compression induced by osmotic shock and cyclic compression in vitro, and muscle contraction in vivo. This function relies on ZAKβ's ability to recognize stress fibers in cells and Z‐discs in muscle fibers when mechanically perturbed. Consequently, ZAK‐deficient mice present with skeletal muscle defects characterized by fibers with centralized nuclei and progressive adaptation towards a slower myosin profile. Our results highlight how cells in general respond to mechanical compressive load and how mechanical forces generated during muscle contraction are translated into MAP kinase signaling.

Abstract
Hydrogel-based regenerative endodontic procedures (REPs) are considered to be very promising therapeutic strategies to reconstruct the dental pulp (DP) tissue in devitalized human teeth. However, the success of the regeneration process is limited by residual bacteria that may persist in the endodontic space after the disinfection step and contaminate the biomaterial. The aim of this work was to develop an innovative fibrin hydrogel incorporating clindamycin (CLIN)-loaded Poly (d,l) Lactic Acid (PLA) nanoparticles (NPs) to provide the hydrogel with antibacterial properties. CLIN-PLA-NPs were synthesized by a surfactant-free nanoprecipitation method and their microphysical properties were assessed by dynamic light scattering, electrophoretic mobility and scanning electron microscopy. Their antimicrobial efficacy was evaluated on Enteroccocus fæcalis by the determination of the minimal inhibitory concentration (MIC) and the minimal biofilm inhibition and eradication concentrations (MBIC and MBEC). Antibacterial properties of the nanocomposite hydrogel were verified by agar diffusion assays. NP distribution into the hydrogel and release from it were evaluated using fluorescent PLA-NPs. NP cytotoxicity was assessed on DP mesenchymal stem cells (DP-MSCs) incorporated into the hydrogel. Type I collagen synthesis was investigated after 7 days of culture by immunohistochemistry. We found that CLIN-PLA-NPs displayed a drug loading of 10 ± 2 μg per mg of PLA polymer and an entrapment efficiency of 43 ± 7%. Antibiotic loading did not affect NP size, polydispersity index and zeta potential. The MIC for Enterococcus fæcalis was 32 μg mL-1. MBIC50 and MBEC50 were 4 and 16 μg mL-1, respectively. CLIN-PLA-NPs appeared homogenously distributed throughout the hydrogel. CLIN-PLA-NP-loaded hydrogels clearly inhibited E. faecalis growth. DP-MSC viability and type I collagen synthesis within the fibrin hydrogel were not affected by CLIN-PLA-NPs. In conclusion, CLIN-PLA-NP incorporation into the fibrin hydrogel gave the latter antibacterial and antibiofilm properties without affecting cell viability and function. This formulation could help establish an aseptic environment supporting DP reconstruction and, accordingly, might be a valuable tool for REPs.

Abstract
Osteoarthritis (OA) is a degenerative disease of the joints which is associated with an impaired production of the cartilage matrix by the chondrocytes. Here, we investigated the role of Lysine-Specific Demethylase-1 (LSD1), a chromatin remodeling enzyme whose role in articular chondrocytes was previously associated with a catabolic activity and which is potentially involved during OA. Following a loss of function strategy and RNA sequencing analysis, we detail the genes which are targeted by LSD1 in human articular chondrocytes and identify COL9A1, a gene encoding the α1 chain of the cartilage-specific type IX collagen, as negatively regulated by LSD1. We show that LSD1 interacts with the transcription factor SOX9 and is recruited to the promoter of COL9A1. Interestingly, we observe that OA cartilage displays stronger LSD1 immunostaining compared with normal, and we demonstrate that the depletion of LSD1 in OA chondrocytes prevents the decrease in COL9A1 following Il-1β treatment. These results suggest LSD1 is a new regulator of the anabolic activity of articular chondrocytes potentially destabilizing the cartilage matrix, since it negatively regulates COL9A1, a gene encoding a crucial anchoring collagen molecule. This newly identified role played by LSD1 may thus participate in the alteration of the cartilage matrix during OA.

Abstract
OBJECTIVE Since the biological effect of cartilage mediators is generally studied in a non-physiologic environment of 21% O2, we investigated the effects of a chronic hypoxia on the capability of articular chondrocytes to respond to one anabolic stimulation. DESIGN Human Articular Chondrocytes (HACs) were cultured under hypoxia and stimulated with the chondrogenic growth factor BMP-2. The phenotype of the chondrocytes was studied by RT-PCR, and the cartilage-specific type II collagen production and deposition were also examined by western immunoblot and immunofluorescence. The Bone Morphogenetic protein (BMP) signalling pathway was also analysed. RESULTS BMP-2 is much more efficient to stimulate the expression of the cartilage-specific gene COL2A1 by HACs when cultured under hypoxia (1%O2) compared to normoxia (21%O2). Analysis of the BMP-activated signalling shows that the Smad pathway is inhibited under hypoxia, whereas p38 MAPK is activated, and is involved in a synergy between hypoxia and BMP signalling, thus contributing to the enhanced anabolic response. CONCLUSIONS Our study shows that hypoxia interplays with a chondrogenic factor and enhances the overall anabolic activity of the HACs. Alternatively to Hypoxia-Inducible Factor (HIF) signalling, and through a cross-talk with the BMP signalling which involves the p38 pathway, hypoxic stimulation markedly increases the capability of chondrocytes to produce the cartilage-specific type II collagen. Therefore our study provides new evidences of the multilayered effects of hypoxia in the anabolic functions of chondrocytes. This understanding may help promoting the anabolic function of articular chondrocytes, and thus improving their manipulation for cell therapy.

Abstract
AIM OF THE STUDY Nasal reconstruction remains a challenge for any surgeon. The surgical indications for nasal reconstruction after oncologic resection, trauma or as part of cosmetic rhinoplasty, are steadily increasing. The current attitude for reconstruction is the use of autologous cartilage grafts of various origins (septal, ear or rib) trying to restore a physiological anatomy but their quantity is limited. Thus, in order to produce an implantable cartilaginous model, we developed a study protocol involving human nasal chondrocytes, growth factors and a composite biomaterial and studied at the molecular, cellular and tissue level the phenotype of the chondrocytes cultured in this model. MATERIALS AND METHODS After extraction of chondrocytes and their amplification on plastic, the cells were cultured for 15 days either in monolayer or within an agarose hydrogel or a composite biomaterial (agarose/high density polyethylene: Medpor(®)) in the presence or not of a cocktail of soluble factors (BIT): bone morphogenetic protein-2 (BMP-2), insulin and triiodothyronine (T3). The quality of the chondrocyte phenotype was analyzed by PCR, western blotting and immunohistochemistry. RESULTS During their amplification in monolayer, chondrocytes dedifferentiate. However, our results show that the BIT cocktail induces redifferentiation of chondrocytes cultured in agarose/Medpor with synthesis of mature chondrogenic markers. Thereby, chondrocytes associated with the agarose hydrogel will colonize Medpor and synthesize an extracellular matrix characteristic of nasal cartilage. CONCLUSION This nasal cartilage tissue engineering protocol provides the first interesting results for nasal reconstruction.

Abstract
Regarding cartilage repair, tissue engineering is currently focusing on the use of adult mesenchymal stem cells (MSC) as an alternative to autologous chondrocytes. The potential of stem cells from various tissues to differentiate towards the chondrogenic phenotype has been investigated and it appears that the most common and studied sources are bone marrow (BM) and adipose tissue (AT) for historical and easy access reasons. In addition to three dimensional environment, the presence of member(s) of the transforming growth factor (TGF-β family and low oxygen tension have been reported to promote the in vitro differentiation of MSCs. Our work aimed at characterizing and comparing the degree of chondrogenic differentiation of MSCs isolated from BM and AT cultured in the same conditions. We also further aimed at and at determining whether hypoxia (2% oxygen) could affect the chondrogenic potential of AT-MSCs. Cells were first expanded in the presence of FGF-2, then harvested and centrifuged to allow formation of cell pellets, which were cultured in the presence of TGF-β3 and/or Bone Morphogenetic Protein-2 (BMP-2) and with 2 or 20% oxygen tension, for 24 days. Markers of the chondrocyte (COL2A1, AGC1, Sox9) and hypertrophic chondrocyte (COL10A1, MMP-13) were monitored by real-time PCR and/or by immunohistological staining. Our data show that BMP-2/TGF-β3 combination is the best culture condition to induce the chondrocyte phenotype in pellet cultures of BM and AT-MSCs. Particularly, a switch in the expression of the pre-chondrogenic type IIA form to the cartilage-specific type IIB form of COL2A1 was observed. A parallel increase in gene expression of COL10A1 and MMP-13 was also recorded. However when AT-MSCs were cultured in hypoxia, the expression of markers of hypertrophic chondrocytes decreased when BMP-2/TGF-β3 were present in the medium. Thus it seems that hypoxia participates to the control of AT-MSCs chondrogenesis. Altogether, these cellular model systems will help us to investigate further the potential of different adult stem cells for cartilage engineering.

Abstract
Articular cartilage has a limited capacity for self-repair after trauma. Besides the conventional surgical techniques for repairing such defects, treatments involve implantation of autologous cells in suspension or within a variety of cell carrying scaffolds such as hyaluronic acid, alginate, agarose/alginate, fibrin or collagen. For the repair of full-thickness osteochondral defects, tissue engineers started to design single- or bi-phased scaffold constructs often containing hydroxyapatite-collagen composites, usually used as a bone substitute. The purpose of this study was to compare the behavior of bovine chondrocytes cultured in collagen-based scaffolds containing or not hydroxyapatite and cross-linked following two different methods. Calf chondrocytes seeded within Hemotèse and Collapat II sponges (SYMATESE biomaterials), chemically cross-linked with glutaraldehyde or EDC/NHS, were maintained up to one month in culture. The cells exhibited a similar behavior in the four scaffolds regarding proliferation level, deposition of glycosaminoglycans in the scaffolds and gene expression of types I, II and X collagens, aggrecan, MMP-1, -13 and the integrin subunits alpha10 and alpha11.

Abstract
The active thyroid hormone, triiodothyronine (T(3)), binds to thyroid hormone receptors (TR) and plays an essential role in the control of chondrocyte proliferation and differentiation. Hypo- and hyperthyroidism alter the structure of growth plate cartilage and modify chondrocyte gene expression in vivo, whilst TR mutations or deletions in mice result in altered growth plate architecture. Nevertheless, the particular roles of individual TR isoforms in mediating T(3) action in chondrocytes have not been studied and are difficult to determine in vivo because of complex cellular and molecular interactions that regulate growth plate maturation. Therefore, we studied the effects of TRalpha and TRbeta on chondrocyte growth and differentiation in primary cultures of neonatal rib chondrocytes isolated from TRalpha- and TRbeta-deficient mice. T(3) decreased proliferation but accelerated differentiation of rib chondrocytes from wild-type mice. T(3) treatment resulted in similar effects in TRalpha-deficient chondrocytes, but in TRbeta-deficient chondrocytes, all T(3) responses were abrogated. Furthermore, T(3) increased TRbeta1 expression in wild-type and TRalpha-deficient chondrocytes. These data indicate that T(3)-stimulated differentiation of primary rib chondrocytes in vitro requires TRbeta and suggest that the TRbeta1 isoform mediates important T(3) actions in mouse rib chondrocytes.

Abstract
OBJECTIVE To determine the best protocol for the preparation of a tissue-engineered cartilage to investigate the potential anti-arthritic and/or anti-osteoarthritic effects of drugs. METHODS Calf articular chondrocytes, seeded in collagen sponges were grown in culture for up to 1 month. At day 14 cultures received interleukin (IL)-1beta (ranging from 0.1 to 20 ng/ml) for 1 to 3 days. Analyses of gene expression for extracellular matrix proteins, collagen-binding integrins, matrix metalloproteinases (MMPs), aggrecanases, TIMPs, IL-1Ra and Ikappa-Balpha were carried out using real-time polymerase chain reaction (PCR). Metalloproteinase activities were analysed in the culture medium using both zymography and fluorogenic peptide substrates. RESULTS We selected a culture for 15 or 17 days with collagen sponges seeded with 10(7) chondrocytes showing a minimal cell proliferation, a maximal sulphated glycosaminoglycan (sGAG) deposition and a high expression of COL2A1, aggrecan and the alpha10 integrin sub-unit and low expression of COL1A2 and the alpha11 integrin sub-unit. In the presence of 1 ng/ml IL-1beta, we observed at day 15 up-regulations of 450-fold for MMP-1, 60-fold for MMP-13, 54-fold for ADAMTS-4 and MMP-3 and 10-fold for ADAMTS-5 and IL-1Ra. Down-regulations of 2.5-fold for COL2A1 and aggrecan were observed only at day 17. At the protein level a dose-dependent increase of total MMP-1 and MMP-13 was noted with less than 15% in the active form. CONCLUSIONS This in vitro model of chondrocyte culture in three dimensional (3D) seems well adapted to investigate the responses of these cells to inflammatory cytokines and to evaluate the potential anti-inflammatory effects of drugs.

Abstract
Bone tissue is densely innervated, and there is increasing evidence for a neural control of bone metabolism. Semaphorin-3A is a very important regulator of neuronal targeting in the peripheral nervous system as well as in angiogenesis, and knockout of the Semaphorin-3A gene induces abnormal bone and cartilage development. We analyzed the spatial and temporal expression patterns of Semaphorin-3A signaling molecules during endochondral ossification, in parallel with the establishment of innervation. We show that osteoblasts and chondrocytes differentiated in vitro express most members of the Semaphorin-3A signaling system (Semaphorin-3A, Neuropilin-1, and Plexins-A1 and -A2). In vitro, osteoclasts express most receptor chains but not the ligand. In situ, these molecules are all expressed in the periosteum and by resting, prehypertrophic and hypertrophic chondrocytes in ossification centers before the onset of neurovascular invasion. They are detected later in osteoblasts and also osteoclasts, with differences in intensity and regional distribution. Semaphorin-3A and Neuropilin-1 are also expressed in the bone marrow. Plexin-A3 is not expressed by bone cell lineages in vitro. It is detected early in the periosteum and hypertrophic chondrocytes. After the onset of ossification, this chain is restricted to a network of cell processes in close vicinity to the cells lining the trabeculae, similar to the pattern observed for neural markers at the same stages. After birth, while the density of innervation decreases, Plexin-A3 is strongly expressed by blood vessels on the ossification front. In conclusion, Semaphorin-3A signaling is present in bone and seems to precede or coincide at the temporal but also spatial level with the invasion of bone by blood vessels and nerve fibers. Expression patterns suggest Plexin-A3/Neuropilin-1 as a candidate receptor in target cells for the regulation of bone innervation by Semaphorin-3A.

Abstract
Osteoarthritis (OA) is the most common of all joint diseases to affect mankind and is characterized by the degradation of articular cartilage. The low availability of normal and pathologic human cartilage and the inability to study the early stages of the disease in humans has led to the development of numerous animal models of OA. The aim of our study was to establish gene expression profiles during the progression of a rabbit model of OA induced by anterior cruciate ligament (ACL) section. Semiquantitative RT-PCR was used to follow expression of several relevant molecules (type II and X collagens, aggrecan, osteonectin, betaig-h3, BiP, TIMP-1, MMP-1, -3, -13, aggrecanase-1, -2) during development of OA in articular cartilage. In parallel, we monitored the activities of collagenase, caseinase, phospholipase A2 and glycosyltransferases (xylosyl-, galactosyl-, glucuronyl- and N-acetyl-galactosaminyl-transferase). Novel cDNA clones for rabbit type X collagen, aggrecanase-1 and -2, osteonectin and BiP were constructed to obtain species-specific primers. Ours result show that MMP-13 (collagenase-3) gene expression increased dramatically early after ACL surgery and remained high thereafter. An increase in MMP-1 (collagenase-1) and MMP-3 expression was also noted with an absence of variation for TIMP-1 expression. In addition, the global MMPs activities paralleled the MMP gene expression. These data together characterize at the molecular level the evolution of OA in this rabbit model. Furthermore, we have undertaken a search for identifying differentially expressed genes in normal and OA cartilage in this model, by differential display RT-PCR. We present here preliminary results with the determination of the best technical conditions to obtain reproducible electrophoresis patterns of differential display RT-PCR.

Abstract
The mRNA expression patterns of several bone morphogenetic proteins (BMPs) and growth differentiation factors (GDFs) in long-term cultures of the clonal mouse chondrocyte cell line MC615 were examined. Distinct spatial and temporal patterns of expression of BMPs and GDFs were observed. The temporal orders of expression were correlated with those of several biochemical markers characteristic of chondrocytic cell differentiation. BMP-1, -2, -5, and -6 mRNA expression increased throughout the chondrogenic process and BMP-4 mRNA expression was not changed. GDF-1 and -3 mRNA expression increased throughout the chondrogenic process, and GDF-5, -6, -8, and -9 mRNA expressions were not changed. Effects of osteogenic protein-1 (OP-1, BMP-7) on the expression patterns of several other members of the BMP family and of the GDF family were also examined. OP-1 downregulated the BMP-1, -4, -5, and -6 mRNA expression by a maximal 3-, 5-, 2.5-, and 3-fold, respectively. The BMP-2 mRNA expression was not changed significantly by a low concentration of OP-1, but was increased at 200 ng/ml at day 7 of treatment. In contrast to the BMPs, OP-1 upregulated significantly the six GDF members examined (GDF-1, -3, -5, -6, -8, and -9) by three- to four-fold. Our findings demonstrate that OP-1 differentially regulates the mRNA expression of several related members of the BMP family and upregulates the mRNA expression of several members of the GDF family. The observations suggest that OP-1 action on cartilage differentiation involves a complex regulation of gene expression of several members of the BMP and the GDF family.

Abstract
The aim of this study was to characterize the cellular phenotypes of articular cartilage and meniscus in rabbits with experimentally induced osteoarthritis (OA), by histological and molecular biological techniques. OA was induced by severing the anterior cruciate ligament of the knee and rabbits were killed 2, 4 or 9 weeks following surgery. Our histological observations show a progressive destruction of extracellular matrix in both tissues. To determine whether these morphological changes could be related to alterations in the regulation of gene expression for a subset of relevant molecules, levels of mRNA for proteinases and one inhibitor (MMP-1, -3 and -13, aggrecanase-1 and -2 and TIMP-1), matrix molecules and one chaperone (type II and X collagens, aggrecan, osteonectin, betaig-h3 and BiP) were assessed by reverse transcription-polymerase chain reaction. Our results indicate that for most markers expression profiles were similar in both tissues. In particular, matrix protein gene expression remained stable or varied little during progression of OA, suggesting a poor repair capacity of the tissues. MMP gene expression increased rapidly whereas aggrecanase gene expression remained stable. These findings suggest that differential regulation of mRNA levels of MMP-1, -3 and -13 on the one hand and aggrecanase-1 and -2 on the other, occurs during OA.

Abstract
With the aim of identifying genes involved in cartilage differentiation, we have used a subtractive hybridization strategy with cDNAs from a chondrocytic cell line (MC615) and mRNAs from a mesenchymal precursor cell line (10T1/2). We have isolated a cDNA clone representing a novel mouse gene. The predicted 368-amino acid protein, designated ZF-12, contains four C(2)H(2)-type zinc finger motifs and one region homologous to the LeR domain, a finger-associated structural domain. ZF-12 mRNAs are expressed during embryonic development and in different organs in adult, including rib cartilage. These data suggest that ZF-12 might play an important role not only in cartilage differentiation, but also in basic cellular processes.

Abstract
In order to study the lineage leading to chondrocyte and osteoblast phenotype in vertebrate development, we examined the effect of recombinant human bone morphogenetic protein (BMP)-2, BMP-4, BMP-12 [or growth and differentiation factor (GDF)-7], and BMP-13 (or GDF-6) on the phenotypic expression of the mouse chondrocyte cell line MC615, grown for 1 or 2 weeks in monolayer. Protein synthesis rates were monitored after incubation with [(14)C]proline. BMP-2 and BMP-4 increased protein synthesis, in agreement with our observation by phase-contrast microscopy of a highly refractile matrix around MC615 cells treated with BMP-2 and -4. Markers of the chondrocytic and osteoblastic differentiation were analyzed at mRNA level. Expression of the type II collagen gene, a marker of the cartilage phenotype, was up-regulated in the presence of low concentration of BMP-2 or -4 (50 ng/ml) and down-regulated at higher concentrations (100-400 ng/ml). In parallel, this expression was stable in the presence of BMP-12 or -13 in the dose range tested (50-400 ng/ml). Expression of the matrix Gla protein (MGP) gene, another marker of cartilage, was also reduced in the presence of 100 ng/ml BMP-2 or -4, while it remained stable in the presence of BMP-12 or -13 at the same concentration. In contrast, expression of the bone Gla protein (BGP) gene, or osteocalcin, a marker of the bone phenotype, was induced when the cells were treated with BMP-2 or -4 but was not detected when the cells were treated with BMP-12 or -13. At the same time, BMP-2 or -4 markedly up-regulated expression of type X collagen mRNA, indicating that MC615 cells possess the ability to express traits associated with endochondral ossification, when exposed to specific BMPs. Furthermore, detailed analysis of type II collagen expression showed that the alternatively spliced transcript collagen IIB, specific for cartilage, is expressed concomitantly with BGP. Therefore, MC615 chondrocytes can simultaneously express chondrocytic and osteoblastic markers, in response to BMP-2 or -4, but show minimal response to BMP-12 (or GDF-7) or to BMP-13 (or GDF-6). These results raise the possibility that chondrocytes in vivo can express osteoblastic properties, provided they are induced by BMP-2 or -4.

Abstract
We have previously shown that SV40 large T oncogene is able to induce mouse chondrocyte proliferation without loss of expression of types II, IX, and XI collagen, as well as cartilage aggrecan and link protein. The cell line obtained (termed MC 615) also expressed some type I collagen in monolayer and we have investigated if anchorage-independent conditions could inhibit type I collagen synthesis and promote hypertrophy and type X collagen synthesis. The MC 615 cells were grown in agarose in the presence of serum, and GAG accumulation, DNA content, and matrix synthesis rates were monitored after incubation with [35S]sulfate and [3H]- or [14C]proline. SDS-PAGE analysis of pepsin-extracted samples showed that type I collagen was still synthesized by the MC 615 cells, from the beginning of the culture and at low or high density. Type II collagen synthesis was demonstrated by immunoblotting, but type X collagen synthesis was not detected, indicating that the MC 615 chondrocytes immortalized by large T were still blocked in their maturation pathway. The cells were also grown over agarose and electron microscopy (E. M.) analysis of the cell aggregates showed an extracellular matrix rich in proteoglycans and in type II-containing collagen fibrils. To gain insight into the role of type IX collagen in cartilage collagen assembly and/or matrix organization, we also immortalized embryonic chondrocytes isolated from mice lacking alpha 1 (IX) collagen and obtained a clone termed 4KO 91. As found for the MC 615 cells, the 4KO 91 cells synthesized type II collagen as demonstrated by Western blotting and some type I collagen identified by the presence of alpha 2(I) chains after electrophoretic analysis of pepsin-digested collagen chains. E. M. analysis of the extracellular matrices synthesized by the two cell lines revealed differences in collagen structure and organization. In the absence of alpha 1 (IX) collagen chains, the collagen fibrils seemed to fuse laterally, suggesting that collagen IX acts as a "spacer" between fibrils, to keep them apart.

Abstract
The expression of type I, II and III collagens genes was examined in human normal and hypochondrogenesis cartilage canals employing electrophoretic analysis, immunohistochemistry and in situ hybridization techniques. In normal cartilage, collagens type I and III were present in perichondrium, in the connective tissue surrounding the vessels of cartilage canals and in the dense fibrous tissue. However, types I and III procollagen mRNAs were detected only in fibroblasts of the perichondrium and of the canals, but not in the polymorphic cells. Type II collagen was present in the cartilage matrix and in the dense fibrous tissue, in good accordance with the localization of type II procollagen mRNAs detected in the chondrocytes and in the polymorphic cells. These data suggest that there are no transitional cells expressing type I, II and III collagen genes and that polymorphic cells are of chondrocytic origin. In the case of hypochondrogenesis, type II collagen was less abundant than in normal cartilage, whereas the corresponding mRNA level was equivalent. That suggests that a postranscriptional regulation of this protein is involved in the decrease of type II collagen production. Type I collagen, unexpectedly detected in the cartilage matrix, was synthesized by chondrocytes and polymorphic cells, suggesting a replacement of type II by type I collagen. The canal hypertrophy observed in this pathological case could thus be due to a modification in the regulation of the growth of cartilage canals caused by a defective cartilage matrix.

Abstract
We have infected primary embryonic mouse limb chondrocytes with a retrovirus carrying simian virus 40 early regions and have obtained a monoclonal mouse chondrocyte line, MC615, that was able to grow on culture dishes for at least 7 months and 20 passages. MC615 cells show expression of simian virus 40 large T (tumor) antigen and express markers characteristic of cartilage in vivo, such as types II, IX, and XI collagen, as well as cartilage aggrecan and link protein. These data show that cell growth induced by large T oncogene expression does not prevent the maintenance of the chondrocytic phenotype.

Abstract
The expression of mRNAs for collagen types I, II, III and for aggrecan core protein was studied in developing human femoral cartilage by in situ hybridization, with special attention given to the cartilage covered by the perichondrium and to the articular surface. In parallel, the synthesis of the related proteins was monitored by immunohistochemistry. The cells metabolically active for type I and type III collagen expression were identified by hybridization using [32P]-labeled cDNA clones coding for human alpha 1(I) and alpha 1(III), respectively. Type II collagen and core protein mRNAs were detected by hybridization with specific [32P]-labeled oligonucleotide probes. In the femoral heads of one 22-week old fetus and of one newborn, our in situ hybridization and immunohistochemical analysis revealed that chondrocytes located immediately subjacent to the perichondrium produced collagen types I, II, III as well as aggrecan; whereas only type II collagen and aggrecan gene expression was detected deeper in the cartilage covered by the perichondrium. This observation supports the hypothesis that the inner cell layers of perichondrium are chondrogenic, with a transient state where cells express all the markers studied here. At the articular surface different patterns of expression were observed at the two developmental stages. After 22 weeks of fetal development only collagen types I and III were expressed by the surface zone cells while in the newborn cartilage, these cells expressed all the molecules studied (collagen types I, II, III and cartilage proteoglycan). At both ages the underlying cartilage cells expressed only the cartilage-specific molecules (type II collagen and aggrecan). Thus a progressive transformation of cartilaginous matrix occurs with time from the deep cartilage up to the surface by addition of new components, i.e. aggrecan and type II collagen. These results supplemented by an immunofluorescence analysis on 20-, 26- and 38-week old fetal femoral heads suggest that expression of collagen and aggrecan in the cartilage covered by the perichondrium and in the cartilage at the articular surface are subject to different regulatory mechanisms during development. Furthermore, the appearance of hybridizable core protein and type II collagen mRNAs at the articular surface, closely followed by the appearance of the proteins for which they code, indicates that core protein and type II collagen expression is regulated primarily at the transcriptional level in this region. Finally, the similar topography observed for the expression of these two proteins suggests that the genes for these two major constituents of cartilage matrix are coordinately regulated during growth of articular cartilage.

Abstract
The dedifferentiation of chondrocytes in culture is classically associated with a transition from a rounded to a spread morphology. However, the loss of chondroitin sulfate proteoglycan (CSPG) and type II collagen gene expression (markers of the differentiated chondrocyte) does not occur for all polygonal or fibroblast-like cells at the same stage of culture. Furthermore, it has been demonstrated that retinoic acid-dedifferentiated chondrocytes can reexpress type II collagen if treated by the microfilament disruptive drug dihydrocytochalasin B, without a return to the spherical shape. In the present study, we have investigated by fluorescent double-staining whether the synthesis of both CSPG and type II collagen by dedifferentiating chick chondrocytes in low density cultures is dependent on a type of actin organization. We report that the synthesis of CSPG and type II collagen synthesis is coincident with the presence of a faint microfibrillar actin architecture but is absent in chondrocytes showing well defined actin cables. This correlation was observed independently of the shapes exhibited by the cells. Moreover, type I collagen (marker of the dedifferentiated chondrocyte) is synthesized mainly in cells showing large actin cables. This study, performed in the absence of drugs, suggests that actin organization, rather than changes in cell shape, is involved in modulating the chondrogenic phenotype in vitro.

Abstract
Chondrocytes isolated from chicken embryo sterna were cultivated in low density monolayer cultures to induce their dedifferentiation. At different stages of the long-term cultures, changes in expression of a cartilage-specific sulfated proteoglycan and cartilage-characteristic type II collagen have been examined and related to the shape change of cells using in situ hybridization and immunocytochemistry. At the beginning of the culture, all cells exhibit a round shape and express the cartilage phenotype. Then, during the course of the culture, chondrocytes flatten and become fibroblast-like, but this morphological modification does not start for all the cells at the same time. Interestingly, the loss of cartilage proteoglycan or type II collagen expression did not occur for all polygonal or fibroblast-like cells. Moreover, we observed a variability in the steady state levels of RNA or protein accumulation among chondrocytes exhibiting a similar shape, as judged by the intensity of hybridization signal or immunofluorescence over the cells. These observations support the hypothesis that the shape change does not have a causative role in the chondrocyte phenotype expression, but is rather a secondary effect of the dedifferentiation process. Furthermore, the disappearance of hybridizable core protein or type II collagen mRNA during the dedifferentiation process was coincident with the disappearance of the proteins for which they code as detected by immunohistochemical staining. This suggest that core protein and type II collagen gene expressions are controlled primarily at the transcriptional level in long-term chondrocyte cultures.

Abstract
As limb mesenchymal cells differentiate into chondrocytes they initiate the synthesis of a cartilage-specific sulfated proteoglycan, cartilage-characteristic type II collagen, and other cartilage-specific proteins. In the present study, in situ hybridization with a 32P-labeled cloned cDNA probe complementary to mRNA encoding the core protein of cartilage proteoglycan has been used to visualize and localize the accumulation of cartilage proteoglycan core protein mRNA sequences during development of the chick limb bud in vivo. When the probe was hybridized to sections through 7-day (stage 32) limbs, an intense hybridization signal was observed over the well-differentiated cartilage rudiments of the limb, while no signal above background was observed over nonchondrogenic tissues including muscle, loose connective tissue, and epidermis. At early stages of limb development, an accumulation of silver grains representing hybridizable core protein mRNA first became detectable in the proximal central core of the limb where the prechondrogenic condensation of mesenchymal cells that characterizes the onset of cartilage differentiation was occurring. In fact, the pattern of silver grain accumulation closely followed the pattern of mesenchymal cell condensation, and no hybridizable core protein mRNA sequences were detectable in the limb bud prior to condensation. Cartilage-characteristic type II collagen mRNA was colocalized with core protein mRNA in the condensing central core of the limb suggesting that the genes for these two major constituents of cartilage matrix are coordinately regulated at the onset of chondrogenesis. Furthermore, the appearance of hybridizable core protein mRNA was closely followed by the appearance of the protein for which it codes as detected by immunohistochemical staining with monospecific antibody. These observations support the hypothesis that at the initial stages of limb chondrogenesis core protein gene expression is controlled primarily at the transcriptional level.
