The Regenerative Potential of Notochordal Cells in a Nucleus Pulposus Explant
STUDY DESIGN In vitro disk explant culture. OBJECTIVE Notochordal cells (NCs) have been shown to upregulate matrix production by nucleus pulposus (NP) cells in coculture. To examine the translation of these in vitro results to a nativelike setting, the regenerative potential of NCs injected into NP tissue was assessed in this study. METHODS NP explants were cultured after injection with NCs...
متن کاملNucleus pulposus explant culture model.
Many of the therapeutic interventions for intervertebral disc degeneration attempt to repopulate the nucleus pulposus (NP) tissue; however, NP cells are heterogeneous and not well characterized. To address this, we have investigated the morphology, extracellular gene and protein expression, and apoptosis changes in NP explants cultured in vitro with or without chondrogenic reagents for differen...
متن کاملNotochordal-cell derived extracellular vesicles exert regenerative effects on canine and human nucleus pulposus cells
During intervertebral disc ageing, chondrocyte-like cells (CLCs) replace notochordal cells (NCs). NCs have been shown to induce regenerative effects in CLCs. Since vesicles released by NCs may be responsible for these effects, we characterized NC-derived extracellular vesicles (EVs) and determined their effect on CLCs. EVs were purified from porcine NC-conditioned medium (NCCM) through size exc...
متن کاملNotochordal cell rich nucleus pulposus tissue increases proteoglycan accumulation and promotes a healthy nucleus pulposus phenotype in human MSCs
pulposus phenotype in human MSCs +Purmessur, D; Godburn K; Abbott, RD: Schek RM; Iatridis JC +University of Vermont, Burlington VT Senior author [email protected] INTRODUCTION Mesenchymal stem cells (MSCs) are an attractive cell source for IVD repair, yet the means of differentiating these cells to a nucleus pulposus (NP) phenotype is not clear and an area of high priority. Notochordal cel...
متن کاملModulating Notochordal Differentiation of Human Induced Pluripotent Stem Cells Using Natural Nucleus Pulposus Tissue Matrix
Human induced pluripotent stem cells (hiPSCs) can differentiate into notochordal cell (NC)-like cells when cultured in the presence of natural porcine nucleus pulposus (NP) tissue matrix. The method promises massive production of high-quality, functional cells to treat degenerative intervertebral discs (IVDs). Based on our previous work, we further examined the effect of cell-NP matrix contact ...
