Identification of novel nucleus pulposus markers
Mesenchymal stem-cell based therapies have been proposed as novel treatments for intervertebral disc degeneration, a prevalent and disabling condition associated with back pain. The development of these treatment strategies, however, has been hindered by the incomplete understanding of the human nucleus pulposus phenotype and by an inaccurate interpretation and translation of animal to human re...
متن کاملNucleus pulposus cell-matrix interactions with laminins.
The cells of the nucleus pulposus (NP) region of the intervertebral disc play a critical role in this tissue's generation and maintenance, and alterations in NP cell viability, metabolism, and phenotype with aging may be key contributors to progressive disc degeneration. Relatively little is understood about the phenotype of NP cells, including their cell-matrix interactions which may modulate ...
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 کاملExhaustion of nucleus pulposus progenitor cells with ageing and degeneration of the intervertebral disc
Despite the high prevalence of intervertebral disc disease, little is known about changes in intervertebral disc cells and their regenerative potential with ageing and intervertebral disc degeneration. Here we identify populations of progenitor cells that are Tie2 positive (Tie2+) and disialoganglioside 2 positive (GD2+), in the nucleus pulposus from mice and humans. These cells form spheroid c...
متن کاملDamping properties of the nucleus pulposus.
BACKGROUND The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the intervertebral disc. The quantification of the damping properties of the nucleus pulposus under physiological large deformations is then a key as...
