3D Neuronal Network Spinal Cord Implant Found Successful at Restoring Walking in Paralysed Mice

Cell therapy, regenerative therapies, and cell reprogramming seem to be the new-age answers for hard-to-cure conditions such as spinal injuries, paralysis, and neural damage. While a lot of new technologies are developed nowadays in biomanufacturing like the morphing polymer for bone growth and the low-gravity biomanufacturing technology that was mentioned in previous articles, researchers are still working on tackling these hard-to-cure conditions day and night.

Now, researchers from Tel Aviv University developed a way to program the cells to use them in spinal cord implants, a development that could provide hope for people suffering from paralysis. Their research has been published in Advanced Science with the title of “Regenerating the Injured Spinal Cord at the Chronic Phase by Engineered iPSCs-Derived 3D Neuronal Networks“.

How did the researchers produce the spinal cord implant?

The procedure is like a newly developed kind of cell therapy. In general, a fatty tissue biopsy is taken from the organism, these cells are reprogrammed to be embryonic-like stem cells. The reprogramming procedure involves “engineering of a functional human neuronal network reported by mimicking the embryonic development of the SC in a 3D dynamic biomaterial-based microenvironment” according to the paper.

And then the newly developed “baby cells” are transferred to patients with helper substances to reduce rejection. By providing the cells with correct development materials, a mini stem-cell supporting environment, and forcing correct interactions through 3D engineering, this new research opens up new undiscovered revolutionary areas in our understanding of cell development and cell therapy.

In terms of testing, the researchers tested the new implant on mice. With paralysis, mice that were “newly paralyzed” had a success rate of 100% in the improvement of mobility. However, with the added chronic spinal cord injuries that have happened a long time ago, the success rate dropped to 80%. Still, that is a huge percentage of success if you think that it is in medical practice. The researchers are now developing a new therapy for humans and plan to begin human testing in three years.

Future with cell therapy

A lot of complex conditions require complex therapies. However, the right technologies are slowly beginning to develop with the ongoing brilliant research in cell therapy and biomanufacturing. As we learn more about cell development, cell reprogramming, and biomaterials, surely an age when we can cure paralysis or similar conditions must come.

As nobody would want to carry the financial, mental, and physical burden of these kinds of conditions, we wish everyone who lives with those the best. We hope science can find a solution for them in their lifetime.
