Stem cell therapy for intervertebral disk regeneration.

Hide Abstract
Intervertebral disk degeneration has been considered an irreversible process characterized by a decrease in cell viability, attenuation of proteoglycan and type II collagen synthesis, and dehydration of nucleus pulposus. Stem cell therapy specifically addresses the degenerative process and offers a potentially effective treatment modality. Current preclinical studies show that mesenchymal stem cells have the capacity to repair degenerative disks by differentiation toward chondrocyte-like cells, which produce proteoglycans and type II collagen. There has been evidence that mesenchymal stem cell transplantation into the intervertebral disk increases the intradiskal magnetic resonance imaging T2 signal intensity, increases the disk height, and decreases the degenerative grade in animal models. Appropriate selection of cell carriers/matrix is important because it may prevent cell leakage into the spinal canal and provide an environment that facilitates cell proliferation and differentiation. Although human cell therapy trials for degenerative disk disease are on the horizon, potential issues might arise. The authors hereby review the current state of regenerative cell therapy in degenerative disk disease, with emphasis in cell source, techniques for cellular expansion, induction, transplantation, potential benefit, and risks of the use of this novel medical armamentarium in the treatment of degenerative disk disease.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
