The study shows that C28/I2 cells can migrate under the influence of CDMP-2 as a chemoattractant or migration stimulator, suggestive of an effect on chondrocytic cells in the intervertebral disc. Further, CDMP-2 can stimulate C28/I2 cells to proliferate and synthesize key extracellular matrix proteins.
Intervertebral disc degeneration creates a significant healthcare burden on industrialized Western society. Recent research into treatment options has highlighted numerous biological strategies to replenish the native disc cells with minimal invasion, although their effectiveness and safety are still under intense investigation. This review provides an outline of the key biological therapies under research currently, including stem cells, biomaterial scaffolds and signaling molecules. Particularly, the focus will be on CDMP-2, a signaling molecule that has been found to possess properties that are therapeutic to disc degeneration. The review will assess the evidence of the molecule’s chondrogenic and chemotactic effects on disc cells and evaluate areas for further research in determining its regenerative potential in the intervertebral disc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
