- A Nature article (https://www.nature.com/articles/d41586-025-00863-0) reports that a paralyzed man has regained the ability to stand and is learning to walk after receiving “reprogrammed” stem-cell therapy.  
- Participants questioned why immunosuppressive drugs were required, suggesting possible allogeneic or partially mismatched cell sources.  
- Clarification emerged that “standing” in this context means unassisted, voluntary standing rather than passive orthotic support, marking a functional motor recovery milestone.
