"The development of regenerative therapies for the intervertebral disc (IVD) is of much interest because IVD degeneration is a major cause of low back pain, one of the leading causes of disability worldwide. The most common approaches are to utilize biomaterials, cells, and/or molecular agents, alone or in combination. Some of these approaches are moving toward clinical implementation and have...
"Low back pain is the leading cause of morbidity worldwide and yet most therapies fail to target the cause and are purely symptomatic or end stage surgical options. Intervertebral disc degeneration is associated with approximately 40% of low back pain cases and thus a target for potential regeneration. Intervertebral disc degeneration is a catabolic process caused by altered cell behaviour and...
"Introduction
Low back pain due to intervertebral disc (IVD) degeneration is a major health and socioeconomic problem throughout the world. In the young and healthy IVD, large and vacuolated notochordal cells (NCs) are present1. These cells are, in some species (e.g. humans and dogs), replaced by chondrocyte-like nucleus pulposus cells (NPCs) during maturation and ageing2. In previous...
"Introduction
The last decade, efforts have been made in developing more effective diagnostics for low back pain. The focus was addressed towards Modic Changes (MCs), pathological signal intensity changes in the vertebral bone marrow and endplates of the intervertebral disc (IVD), which can be detected on Magnetic Resonance Imaging (MRI)1. In contrast to the human situation, little is known...
"Introduction: Low back pain (LBP) is a leading cause of disability worldwide and intervertebral disc (IVD) degeneration (IVDD) is a major contributor of LBP1. The IVDD is accompanied and often preceded by the replacement of large vacuolated nucleus pulposus cells (NPCs) by non-vacuolated, clustered cells in the notochordal cells (NCs) of the IVD2. The iPSpine project aims to re-populate the...
"Back pain is often associated with intervertebral disc (IVD) degeneration. Beside surgery, novel treatments relying on stem cell injection have been tested. Unfortunately, the outcomes are disappointing because of cell leakage and incomplete differentiation. Nowadays, a consensus exists on the necessity to encapsulate stem cells within a hydrogel to maintain them in situ and favor their...
Loss of large, vacuolated notochordal cells (NCs) from the human intervertebral disc (IVD) is thought to initiate degeneration and associated back pain. It is therefore hypothesised that implantation of NCs may halt or reverse degeneration and thus relieve back pain. However, NCs are lost in early childhood, therefore iPSCs differentiation to NCs offers a clinically-viable cell source. Here we...
