Notochordal 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 ...
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 کاملConditioned medium derived from notochordal cell-rich nucleus pulposus tissue stimulates matrix production by canine nucleus pulposus cells and bone marrow-derived stromal cells.
OBJECTIVES Conditioned medium derived from notochordal cell-rich nucleus pulposus tissue (NCCM) was previously shown to have a stimulatory effect on bone marrow stromal cells (BMSCs) and nucleus pulposus cells (NPCs) individually, in mixed species in vitro cell models. The objective of the current study was to assess the stimulatory effect of NCCM on NPCs in a homologous canine in vitro model a...
متن کاملCollagen type II is downregulated in the degenerative nucleus pulposus and contributes to the degeneration and apoptosis of human nucleus pulposus cells
Degenerative disc disease (DDD) is a common degenerative condition initiated mainly within the nucleus pulposus (NP). To date, the etiopathogenesis of DDD remains unclear, and because no effective therapeutic strategies are available to target its pathological processes, DDD is still treated with symptomatic interventions that are far from adequate. Collagen type II is one of the major matrix c...
