Tagln+ progenitors contribute to the development and maintenance of nucleus pulposus

Project description:Failure of intervertebral disc components, e.g. the nucleus pulposus causes intervertebral disc disease and associated low-back pain. Despite the high prevalence of disc disease, the changes in intervertebral disc cells and their regenerative potential with ageing and degeneration are not fully elucidated. Understanding the cell lineage, cell differentiation and maintenance of nucleus pulposus may have therapeutic application for the regeneration of degenerative disc, with significant impact for healthy ageing. Here we found that TAGLN expressing cells are present in human healthy nucleus pulposus, but diminish in degenerative disc. By lineage analyses in mice, we found cells in the nucleus pulposus are derived from a peripherally located population of notochord-derived Tagln expressing cells (PeriNP cells). The PeriNP cells are proliferative and can differentiate into the inner part of the nucleus pulposus. The Tagln+ cells and descendants diminish during aging and puncture induced disc degeneration. The maintenance and differentiation of PeriNP cells is partially regulated by Smad4 dependent signaling. Removal of Smad4 by nucleus pulposus specific Cre (Foxa2mNE-Cre), results in decreased Tagln+ cells and abnormal disc morphology, leading to disc degeneration. Our findings propose that the PeriNP Tagln expressing cells are a pool of notochord-derived progenitors that are important for maintenance of the nucleus pulposus and provide insights for regenerative therapy against intervertebral disc degeneration.

Single cell sequencing of human nucleus pulposus

Project description:In order to discover the cell type in nucleus pulposus and find the cell type specific genetic change during intervertebral disc degeneration, we applied single cell RNA sequencing of nucleus pulposus tissue from degenerated and non-degenerated disc.

N6-methyladenosine circRNA Epitranscriptomic Microarray of human nucleus pulposus in intervertebral disc degeneration

Project description:It is well documented that low back pain is a common condition and the leading cause of disability globally. A widely recognised contributor to low back pain is intervertebral disc degeneration (IVDD), which is the major cause of a series of degenerative disc diseases. Recently, it has been reported that circRNAs are involved in the development of IVDD. However, the mechanisms by which m6A modifies circRNA in nucleus pulposus cells remain poorly understood. Here, we aim to identify differentially expressed m6A circRNAs in degenerative nucleus pulposus cells and figure out how the circRNAs regulate IVDD progression and the m6A methylation functions.

Single-cell sequencing reveals cellular heterogeneity of nucleus pulposus in intervertebral disc degeneration

Project description:Nucleus pulposus (NP) plays a vital role in intervertebral disc degeneration (IVDD). Previous studies have revealed cellular heterogeneity in the NP tissue during IVDD progression. Here, we used single cell RNA sequencing (scRNA-seq) to analyze the cellular and molecular alterations of diverse cell clusters during IVDD.

miR-seq analysis of nucleus pulposus tissues from compression-induced intervertebral disc degeneration rats

Project description:Intervertebral disc degeneration (IDD) is an important cause of low back pain. And abnormal mechanical factors are an important contributor to IDD. To identify mechanical responsive miRNAs in IDD, we used a custom-made compression device to establish IDD in rats and considered as IDD group, and the Sham group was inserted with K-wires into coccyxes only. After four weeks, rat nucleus pulposus tissues were obtained for miR-seq analysis.

Expression data from bovine nucleus pulposus interverteral disc cells

Project description:Assessment of the putative differential gene expression profiles in high osmolality-treated bovine nucleus pulposus intervertebral disc cells for a short (5 h) and a long (24 h) time period. Identification of novel genes up- or down-regulated as an early or a late response to hyperosmotic stress. A 5 and 24 h-hyperosmotic treatment of nucleus pulposus cells led to transcriptional changes in >100 and 200 genes, respectively. Nucleus pulposus intervertebral disc cells were exposed to hyperosmotic stress for 5 and 24 h before RNA extraction and transcriptomics analysis. Three biological replicates were tested for each condition. Selected genes found to be differentially expressed were validated by RT-qPCR. Functional experiments were performed in order to assess the role of specific proteins encoded by genes found to be up-regulated in the osmo-reguatory response of intervertebral disc cells.

RNAseq analyses of nucleus pulposus cells treated with control siRNA and LINC02569 siRNA

Project description:Nucleus pulposus cells (NPCs) were used to examine the effect of LINC02569, a novel lncRNA. In particular, its effect in intervertebral disc degeneration was determined. Treatment of LINC02569 siRNA (si-02569) was to be compared with negative control siRNA (si-NC).

The role of SDC4 in nucleus pulposus tissue homeostasis

Project description:Transcriptional analysis of 6-month-old primary nucleus pulposus (NP) mouse disc tissues from wild-type (WT) and SDC4 KO mice, which harbor deletions of exon 2 to part of exon 5 that endcodes the N-terminal coding region. Breeder mice were provided by Dr. Michael Simons. SDC4's regulation of cytokine-dependent activation of the aggrecanse ADAMTS-5 is linked with inflammation-associated intervertebral disc degeneration. In this study, we aim to establish the role of SDC4 in matrix homeostasis under the context of aging.
