Single-cell RNA-seq of the tendon enthesis cells

Project description:Our studies used scRNA-seq analysis to get a full map of transcriptional profiles of enthesis cells and also a seprate Gli1-lineage enthesis stem cells. By harvesting enthesis cells from different development stages for scRNA-seq analysis, we revealed enthesis cell heterogeneity and identified six cell sub-populations using scRNA-seq. We infered cell differentiation trajectories for enthesis stem cells differentiating into mineralizing chondrocytes. A gene regulatory network analysis combined fluorescent in situ hybridization were then used to identify a number of transcription factors coordinating tenogenesis, chondrogenesis, and osteogenesis to form an enthesis with spatially graded mineralization.To further define the enthesis stem cell population, enthesis Gli1-lineage cells were isolated and their transcriptomes were characterized at single cell resolution. These specific Gli1-responsive cells had a linear trajectory and a capacity of chondrogenesis and osteogenesis. The full characterization of transcriptional landscape of tendon enthesis stem cells demonstrates a promising therapeutic strategies using this cell source for enthesis regeneration.

Effect of optogenetic-induced muscle loading on the transcriptomics of murine Achilles tendon and calcaneus

Project description:We used optogenetics to induce skeletal muscle contraction and unilaterally load the Achilles tendon and enthesis in young (i.e., during growth) Acta1Cre;Ai32 mice. We then performed gene expression analysis using data obtained from RNA-seq of optogenetically loaded tendon and enthesis (bone) at two time points.

Single-cell RNA sequencing reveals cellular and molecular heterogeneity in fibrocartilaginous enthesis formation

Project description:The attachment site of the rotator cuff (RC) is a classic fibrocartilaginous enthesis, which is the junction between bone and tendon with typical characteristics of a fibrocartilage transition zone. Enthesis development has historically been studied with lineage tracing of individual genes selected a priori, which does not allow for the determination of single-cell landscapes yielding mature cell types and tissues. Here, in together with open source GSE182997 datasets (3 sample) provided by Fang et al, we applied Single-cell RNA sequencing (scRNA-seq) to delineate the comprehensive postnatal RC enthesis growth and the temporal atlas from as early as postnatal day 1 up to postnatal week 8. And we furtherly performed single cell spatial transcriptomic sequencing on postnatal day 1 mice enthesis, in order to deconvoluted bone-tendon junction (BTJ) chondrocytes onto spatial spots. In summary, we deciphered the cellular heterogeneity and the molecular dynamics during fibrocartilage differentiation. Combined with current spatial transcriptomic data, our results provide a transcriptional resource that will support future investigations of enthesis development at the mechanistic level and may shed light on the strategies for enhanced RC healing outcomes.

RNA-seq analysis of Scx-lineage cell depletion to investigate tendon cell functions during flexor tendon healing

Project description:Little is understood about the roles of tendon cells during flexor tendon healing. To better understand tendon cell functions, the Scx-Cre mouse was crossed to the DTR mouse model to facilitate scleraxis lineage cell depletion prior to acute flexor tendon injury and repair. WT (cre-) and experimental (cre+) mice underwent complete transection and repair of the flexor digitorum longus tendon. Repaired tendons were harvested at 14 and 28 days post-repair for bulk RNA-Seq analysis to examine possible mechanisms driving differential healing due to Scx lineage cell depletion.

Single-cell transcriptomic profiling reveals distinct mechanical responses between normal and diseased tendon progenitor cells

Project description:Regenerative medicine approaches utilizing stem cells offer a promising strategy to address tendinopathy, a class of common tendon disorders associated with pain and impaired function. Tendon progenitor cells (TPCs) are important in healing and maintaining tendon tissues. Here we provide a comprehensive single cell transcriptomic profiling of TPCs from three normal and three clinically classified tendinopathy samples in response to mechanical stimuli. Analysis reveals seven distinct TPC subpopulations including subsets that are responsive to the mechanical stress, highly clonogenic, and specialized in cytokine or growth factor expression. The single cell transcriptomic profiling of TPCs and their subsets serves as a foundation for further investigation into the pathology and molecular hallmarks of tendinopathy in mechanical stimulation conditions.

Gene expression profile at single cell level of injured enthesis at 7 day post repair operation from wild type and Nlrp3 knockout mice

Project description:The repair of injured enthesis remains clinically challenging in sports medicine. We have proved that the activation of Nlrp3 inflammasomes suppressed enthesis regeneration. So we used single cell RNA-seq to uncover the mechanisms by which Nlrp3 inflammasomes modulate enthesis regeneration
