In vivo's treatment of SCI is only thing that they are working on---they have proprietary patents on other very lucrative treatements--including a way of injecting hydrogel impermeated with steroids/NSAIDs into the site of chronic/acute nerve root injury-in patients with chronic back pain/prostate cancer metastatsis that may be impinging upon never roots etc.
Frank Reynolds has also alluded to the developmet of a line of chronic "SCI" rodents--if the scaffold technology mixed with neural stem cells is successful in these animals--you can be sure the FDA may loosen their restrictions on the use of neural stem cells to expediate these tests in humans (especially since they have recently said they will more quickly approve treatments that have "societal benefits")
Start at the beginning as they should? Not really. They can easily partner with a stem cell company. If the bio scaffold works, surely this kind of collaboration would be fast-tracked through FDA via humanitarian pathways. Mr. Stevens, are you short, an investor in a competing technology, or just do not understand this science?
