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.

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.
