Takeaway
In people with multiple sclerosis (MS), repeated intrathecal (IT) injections of autologous mesenchymal stem cell-derived neural progenitors (MSC-NPs) are safe for long-term use, and can lead to a 2-year post-treatment sustained reversal in disability or lack of disease progression.
Why this matters ?
This study adds to the limited data on the long-term safety and efficacy of IT-MSC-NP injections in people with MS.
