Project description:Osteoarthritis (OA) impacts hundreds of millions of people worldwide, with those affected incurring significant physical and financial burdens. Injury to the articular surface is a major contributing risk factor for the development of OA. Current cartilage repair strategies are moderately effective at reducing pain but often replace damaged tissue with biomechanically inferior fibrocartilage. Here we describe the development, transcriptomic ontogenetic characterization and quality assessment at the single cell level, as well as the scaled manufacturing of an allogeneic pluripotent stem cell-derived articular chondrocyte formulation that exhibits long-term functional repair of porcine articular cartilage. These results define a new potential clinical paradigm for articular cartilage repair and mitigation of the associated risk of OA.

Project description:The aim of the current study was to identify molecular markers for articular cartilage that can be used for the quality control of tissue engineered cartilage. Therefore a genom-wide expression analysis was performed using RNA isolated from articular and growth plate cartilage, both extracted from the knee joints of minipigs. Keywords: Native material or primary cells isolated from articular cartilage and growth plate cartilage Articular and growth plate cartilage were taken for RNA extraction and hybridization on Affymetrix microarrays. Furthermore chondrocytes from each type of cartilage were isolated and cell culture was started and terminated at day 10 or day 20. Total RNA from cultivated cells was extracted, and hybridization on Affymetrix microarrays was performed.

Project description:Focal lesions of articular cartilage give rise to pain and reduced joint function and may, if left untreated, lead to osteoarthritis. Implantation of in vitro generated, scaffold-free autologous cartilage discs may represent the best treatment option. Here we compare articular chondrocytes (ACs) and bone marrow-derived mesenchymal stromal cells (MSCs) for their ability to make scaffold-free cartilage discs.

Project description:Chondrocyte gene expression was analyzed to study mechanisms involved in the structural and functional adaptation of articular cartilage during postnatal maturation. Transcriptional profiling was used to compare articular chondrocytes between four neonatal and four adult horses. Expressional differences featured matrix proteins and matrix-modifying enzymes reflecting the transition from cartilage growth to cartilage homeostasis.

Project description:Articular cartilage is deprived of blood vessels and nerves, and the only cells residing in this tissue are chondrocytes. The molecular properties of the articular cartilage and the architecture of the extracellular matrix demonstrate a complex structure that differentiates on the depth of tissue. Osteoarthritis (OA) is a degenerative joint disease, the most common form of arthritis, affecting the whole joint. It is associated with ageing and affects the joints that have been continually stressed throughout life including the knees, hips, fingers, and lower spine region. OA is a multifactorial condition of joint characterised by articular cartilage loss, subchondral bone sclerosis, and inflammation leading to progressive joint degradation, structural alterations, loss of mobility and pain. Articular cartilage biology is well studied with a focus on musculoskeletal diseases and cartilage development. However, there are relatively few studies focusing on zonal changes in the cartilage during osteoarthritis.

Project description:While prior work has established that articular cartilage arises from Prg4-expressing perichondrial cells, it is not clear how this process is specifically restricted to the perichondrium of synovial joints. We document that the transcription factor Creb5 is necessary to initiate the expression of signaling molecules that both direct the formation of synovial joints and guide perichondrial tissue to form articular cartilage instead of bone. Creb5 promotes the generation of articular chondrocytes from perichondrial precursors in part by inducing expression of Wif1, which blocks a Wnt5a autoregulatory loop in the perichondrium. Postnatal deletion of Creb5 in the articular cartilage leads to loss of both flat superficial zone articular chondrocytes coupled with a loss of both Prg4 and Wif1 expression; and a non-cell autonomous up-regulation of Ctgf. Our findings indicate that Creb5 promotes both joint formation and the subsequent development of articular chondrocytes by disrupting a Wnt5a positive-feedback loop in the perichondrium.

Project description:Developmental dysplasia of the hip (DDH) is one of the significant risk factors for hip osteoarthritis. In order to investigate the factors that induce early articular cartilage degeneration of the hip joints that are exposed to reduced dynamic loads arising from hip dislocation , we created rodent models of hip dislocation by swaddling. Notably, expression of periostin (Postn) was increased in the acetabular articular cartilage of the DDH models; Postn was a candidate gene associated with early articular cartilage degeneration. We showed that early articular cartilage degeneration was suppressed in Postn-/- DDH mice. Furthermore, a microgravity environment induced the expression of Postn in chondrocytes through STAT3 signaling. Postn induced catabolic factors, interleukin-6 and matrix metalloproteinase 3, in articular chondrocytes through integrin-nuclear factor κB signaling. Additionally, interleukin-6 stimulated Postn expression through STAT3 signaling. Thus, Postn plays a critical role in early articular cartilage degeneration associated with hip dislocation.

Project description:To identify genes that maintain the homeostasis of the articular cartilage, we compared gene expression profiles of adult articular cartilage chondrocytes with that of growth plate cartilage chondrocytes in adult (10-week-old) Sprague Dawley (SD) rats. Furthermore, to identify genes that have a potency to regenerate the articular cartilage, we compared gene expression profiles of superficial layer chondrocytes of infant epiphyseal cartilage which form articular cartilage with that of the deep layer chondrocytes which form growth plate cartilage in infant (6-day-old) SD rats.

Project description:Objectives Traditional approaches to study Progressive Pseudorheumatoid Arthropathy of Childhood (PPAC) failed to uncover how loss-of-function mutations in Wnt inducible secreted protein 3 (WISP3) cause premature cartilage failure in children. We developed a human induced pluripotent stem cell (hiPSC)-based model of cartilage development to elucidate pathological changes in WISP3-deficient articular cartilage tissues compared to WISP3-sufficient isogenic cartilage tissues. Methods We generated iPSCs from 2 patients with PPAC, and we corrected the disease-causing mutation in one of these lines using CRISPR/Cas9. We also created a WISP3-knockout human embryonic stem cell line. We generated articular cartilage tissues from these hPSCs by established directed differentiation methods. Bioinformatic analyses were used to identify differentially expressed genes (DEGs) and cell type abundances, which were validated by quantitative RT-qPCR and in situ hybridization. Results WISP3-deficient articular cartilage tissues exhibited significantly different transcriptomic profiles and cellular composition compared with their isogenic controls. WISP3-deficient cartilage transcriptomes exhibited enriched biological processes such as TGFb signaling and epithelial to mesenchymal transition. We validated increased expression of TGFb-related genes in WISP3-deficient cartilage, and determined that the abundance of chondrocyte subtypes was altered compared with isogenic controls. Conclusions We developed a robust and reproducible model of iPSC-derived cartilage development to better understand the role of WISP3 in cartilage biology, and the pathology of cartilage failure associated with loss of WISP3 in patients with PPAC. We identified several altered biological processes and signaling pathways in WISP3-deficient cartilage that can be validated in the future with additional patient-derived cell lines, or large animal models.
