Expression data from post-natal rat Achilles tendons

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.

Regional transcriptomics and mechanical properties of rat Achilles tendons

Project description:The transcriptome of different tendons varies based on anatomical location and is likely influenced by the biomechanical loading environment. While differences in biologic and mechanical properties of whole tendons have been assessed, less is understood about differences within a tendon along its proximal-distal axis. Therefore, our objective was to determine the characteristics of and relationship between the transcriptomes and mechanical properties of a single tendon.

Structure-function Relationships in Human Tendons: Interfascicular Matrix Specialisation in the Achilles Tendon C4PR_LIV

Project description:Tendon is a highly aligned connective tissue, in which the macro-structure consists of collagen-rich fascicles surrounded by interfascicular matrix (IFM). In a series of recent studies in equine tissue, we have demonstrated specialisation of tendon composition, structure and mechanics to achieve the tendon’s functional requirements, specifically reporting extensive specialisation of the IFM region in the energy storing superficial digital flexor tendon. We have also demonstrated loss of functional specialisms with ageing, leading to a hypothesised new paradigm for tendinopathy, focused on the importance of the IFM. However, to date, there have been no studies focused on structure-function specialisation or the IFM in functionally distinct human tendons. Here, we compare the positional anterior tibialis tendon and energy storing Achilles tendon, performing a detailed analysis of the composition and mechanical properties of both fascicle and IFM regions, to test the hypothesis that the IFM in the energy storing Achilles tendon has specialised composition and mechanical properties, and that these specialisations are lost with ageing. We demonstrate that the IFM is specialised in the energy storing Achilles tendon, with greater elasticity and fatigue resistance than in the positional anterior tibialis tendon. While there were few age-related alterations in mechanics, we did identify age-related alterations in the IFM proteome of the Achilles tendon specifically, which is predicted to be regulated by TGF-beta signalling and may be responsible for the trend towards decreased fatigue resistance observed in the Achilles IFM with ageing.

Transcriptional analysis of tendons from mice with a tenocyte-specific deletion of IGF1R

Project description:We report RNA sequencing data from the plantaris tendons of adult male mice in the C57Bl/6 background that either have the IGF1 receptor (IGF1R) present in their tendons (Scx:IGF1R+) or mice in which IGF1R has been deleted in tenocytes expressing scleraxis (Scx:IGF1R-). Mice were created by crossing ScxCreERT2 mice with IGF1R flox/flox mice. Mice were treated with tamoxifen for 5 days to induce recombination at the IGF1R allele, and then subjected to a synergist ablation procedure in which the Achilles tendon is removed, resulting in compensatory growth of the plantaris tendon. Mice were analyzed either 7 or 14 days after synergist ablation. Control mice that did not undergo tamoxifen treatment or synergist ablation were also studied.

Spatial transcriptomics of the achilles tendon harvested from the injury site with and without TrkA neuronal inhibition

Project description:Peripheral afferent neurons terminate at the surfaces of tendons, yet their role after injury beyond nociceptive functions remain unclear. Using transgenic animal models, sensory neurons were found to sprout after Achilles tendon injury in domains of Nerve growth factor (NGF) expression. Conditional deletion of Ngf in either myeloid or mesenchymal cell types led to tendon repair defects – findings phenocopied by inactivation of TrkA (Tropomyosin receptor kinase A) using a knockin mouse model. We sought to identify the signals modulated with neural TrkA inhibition. A combination of single cell and spatial transcriptomic analysis was performed on the Achilles injury site of TrkA^F592A animals and compared them to TrkA^WT.
