Collagen10-Cre;Rosa26-tdTomato e16.5 single cell RNA-sequencing

ABSTRACT: In order to assess the descendants of hypertrophic chondrocytes, we utilized Collagen10-Cre;Rosa26-tdTomato mouse total bone isolated at e16.5 by Collagenase II digestion after mechanical digestion and soft tissue removal. After sequencing and downstream analysis using Seurat, we observed clusters of cells with gene profiles matching classically defined chondrocytes, skeletal stem and progenitor cells (SSPCs), and osteoblasts. Trajectory analysis reveals that the SSPCs lie intermediate to the transition of chondrocyte to osteoblast. We conclude that hypertrophic chondrocytes dedifferentiate to this progenitor stage before further differentiation.

Collagen10-Cre;Rosa26-tdTomato bone marrow single cell RNA-sequencing

Project description:In order to assess the descendants of hypertrophic chondrocytes, we utilized Collagen10-Cre;Rosa26-tdTomato mouse bone marrow harvested at 2 months of age by centrifugation and light Collagenase II digestion. After sequencing and downstream analysis using Seurat, we observed clusters of cells with gene profiles matching classically defined skeletal stem and progenitor cells as well as CXCL12 abundant reticular (CAR) cells. These cells appear to be upstream of both osteoblasts and adipocytes. We conclude that hypertrophic chondrocytes dedifferentiate to this progentior stage before further differentiation.

Collagen10a1-Cre;Rosa26-tdTomato Bone marrow colony forming units

Project description:To assess if descendants of the hypertrophic chondrocytes behaved as skeletal stem and progenitor cells, we performed colony unit formation. We observed a near equal proportion of colonies derived from hypertrophic chondrocytes (tomato+) and derived from other sources (likely periosteum). We performed bulk RNA-sequencing on 3 colonies from each origin to compare the gene profiles and potential differentiation capacity or niche support.

Transcription profiling of Bos taurus hypertrophic growth plate chondrocytes vs. reserve zone chondrocytes

Project description:Growth plate chondrocytes were isolated from the distal metacarpus of young dairy cattle (all under 10 mo of age), the chondrocytes were released from the extracellular matrix by digestion with Collagenase P for 4 hours, and the various zones of the growth plate were separated by density centrifugation. The least-dense Hypertrophic Zone (HZ) cells were compared to the most-dense Reserve Zone (RZ) cells. 6 pairs of HZ vs RZ were compared by microarray. Experiment Overall Design: Growth plate chondrocytes were isolated from the distal metacarpus of young dairy cattle (all under 10 mo of age), the chondrocytes were released from the extracellular matrix by digestion with Collagenase P for 4 hours, and the various zones of the growth plate were separated by density centrifugation. The least-dense Hypertrophic Zone (HZ) cells were compared to the most-dense Reserve Zone (RZ) cells. Six independent sample pairs of HZ vs RZ were compared by microarray.

The regulatory mechanism of Serinc5 expression in chondrocytes [ATAC-seq]

Project description:Chondrocytes undergo a series of sequential differentiation steps which result in the formation of a unique hierarchical columnar structure including proliferating, pre-hypertrophic and hypertrophic chondrocytes. Pre-hypertrophic chondrocytes, which exist in the transitional stage between proliferating and hypertrophic chondrocytes, are a rare cell population in the growth plate but critical for endochondral bone development. However, the molecular basis of pre-hypertrophic chondrocytes largely remains elusive. The purpose of this study is to identify novel marker gene and uncover regulatory mechanism of marker gene expression.

Identification of rat Rosa26 locus enables generation of knock-in rat lines ubiquitously expressing tdTomato.

Project description:Recent discovery of a method for derivation and culture of germline-competent rat pluripotent stem cells (PSCs) enables generation of transgenic rats or knock-out rats via genetic modification of such PSCs. This opens the way to use rats, as is routine in mice, for analyses of gene functions or physiological features. In mouse or human, one widely used technique to express a gene of interest stably and ubiquitously is to insert that gene into the Rosa26 locus via gene targeting of PSCs. Rosa26 knock-in mice conditionally expressing a reporter or a toxin gene have contributed to tracing or ablation of specific cell lineages. We successfully identified a rat orthologue of the mouse Rosa26 locus. Insertion of tdTomato, a variant of red fluorescent protein, into the Rosa26 locus of PSCs of various rat strains allows ubiquitous expression of tdTomato. Through germline transmission of one Rosa26-tdTomato knock-in embryonic stem cell line, we also obtained tdTomato knock-in rats. These expressed tdTomato ubiquitously throughout their bodies, which indicates that the rat Rosa26 locus conserves functions of its orthologues in mouse and human. The new tools described here (targeting vectors, knock-in PSCs, and rats) should be useful for a variety of research using rats.

Transcription profiling of chicken proliferative and hypertrophic chondrocytes

Project description:Longitudinal bone growth depends upon the execution of an intricate series of cellular activities by epiphyseal growth plate chondrocytes. In order to better understand these coordinated events, microarray analysis was used to compare gene expression in chondrocytes isolated from the proliferative and hypertrophic zones of the avian growth plate. In this experiment we compared pooled samples of proliferative and hypertrophic chondrocytes isolated from the chick growth plate. The expression of 745 genes was found to differ 3-fold or greater at the 0.05 level of probability. Experiment Overall Design: We examined 8 samples using arrays: 4 from proliferative and 4 from hypertrophic chondrocytes.

Flightless I is a novel catabolic factor of chondrocytes that promotes hypertrophy and cartilage degeneration in osteoarthritis

Project description:Synovial macrophages that are activated by cartilage fragments initiate synovitis, a condition that promotes hypertrophic changes in chondrocytes leading to cartilage degeneration in OA. In this study, we analyzed the molecular response of chondrocytes under condition of this type of stimulation to identify a molecular therapeutic target. Stimulated macrophages promoted hypertrophic changes in chondrocytes resulting in production of matrix-degrading enzymes of cartilage. Among the top-upregulated genes, FliI was found to be released from activated chondrocytes and exerted autocrine/paracrine effects on chondrocytes leading to an increase in expression of catabolic and hypertrophic factors. Silencing FliI in stimulated cells significantly reduced expression of catabolic and hypertrophic factors in cocultured chondrocytes. Our further results demonstrated that the FliI-TLR4-ERK1/2 axis is involved in the hypertrophic signaling of chondrocytes and catabolism of cartilage. Our findings provide a new insight into the pathogenesis of OA and identify a potentially new molecular target for diagnostics and therapeutics.
