Project description:We have compared the gene expression profile of post-natal 1 day and 7 day rat Achilles tendons. Post-natal 1 day and 7 day rat Achilles tendons were collected. Each sample contains at least two individuals. Total RNA was extracted and fragmented biotin-tagged cRNA was hybridized to Rat Genome 230 2.0 Array.

Project description:We have compared the gene expression profile of rat Achilles tendon-derived stem cells in post-natal tendon development. Rat tendon stem/progenitor cells (TSPCs) were isolated at different stages of post-natal development: TSPCs-1d, TSPCs-7d and TSPCs-56d.

Project description:We have compared the gene expression profile of rat Achilles tendon-derived stem cells in post-natal tendon development. Rat tendon stem/progenitor cells (TSPCs) were isolated at different stages of post-natal development: TSPCs-1d, TSPCs-7d and TSPCs-56d. TSPCs at different post-natal development stages (1d, 7d and 56d) were isolated, cultured and used for microarray analyses at passage 2. All TSPCs in this study were of isolated from more than one individual. Total RNA was extracted and fragmented biotin-tagged cRNA was hybridized to Rat Genome 230 2.0 Array.

Project description:The Achilles tendon is the thickest tendon in the human body, and Achilles tendinopathy is its most prevalent disorder, often considered a consequence of overuse. While disruption to the collagen fibers represents a significant manifestation of Achilles tendinopathy, strikingly little is known about the mechanisms by which healthy tendon accumulates damage in vivo.As existing studies of tendon biomechanics and mechanobiology predominantly relied on in vitro or ex vivo experiments on isolated tissues, it is still largely unknown whether and how disruptions occur to the collagen molecules in healthy Achilles tendons following physiological activities. We reported the first RNA-seq analysis reflecting transcriptome changes in healthy rat Achilles tendons following running, providing a resource for future investigations in tendon mechanobiology and sports medicine.

Project description:Knee osteoarthritis (KOA), as a degenerative multifactorial disease, affects the quality of life and mental health of patients, and also brings a huge socioeconomic burden. Treating synovitis have shown promise as anti-inflammatory therapeutics in mitigating OA symptoms and disease progression. Here, by analysing synovial single-cell sequencing (scRNA-seq) data from KOA, we found that synovial fibroblasts (FLS) in OA synovium showed a distinct pro-inflammatory phenotype. We collected synovial tissue from patients with clinical OA as well as from healthy donors, and histological examination was consistent with findings in scRNA-seq. Inspired by recent cross-tissue fibroblast lineage studies, we identified by sequencing that healthy FLS in synovial tissues share transcriptome-level similarities with dermal fibroblasts (DFb). Subsequently, we revealed the local as well as systemic distribution of intra-articular injected DFbs by constructing/extracting two types of rat fibroblasts (luciferase DFbs as well as GFP DFbs). The results demonstrate that DFbs can be locally retained in the synovium for up to three weeks following targeted engrafting on it. And intra-articular injection does not result in DFbs migration to vital organs or the occurrence of histological changes in these organs. A rat model of KOA was constructed by anterior cruciate ligament transection (ACLT) in order to study the therapeutic effect of DFbs on KOA. After injection, the rats showed improvement in painful gait. In addition, histological as well as imaging results showed reduced synovitis and improvement in articular cartilage. Finally we verified the protective effect of DFbs on cytokine-stimulated chondrocytes in a co-culture system.
