After 25 years of research, Brazilian scientists led by Dr. Tatiana Coelho de Sampaio at the Federal University of Rio de Janeiro (UFRJ) have developed Polylaminin, a drug derived from placental proteins that shows the ability to regenerate damaged spinal cords. According to Apple’s Bite, the drug was unveiled in September 2025 and is being hailed as the world’s first treatment capable of reversing spinal cord injuries without implants.
Polylaminin works by stimulating the growth of new axons and rejuvenating mature neurons. It’s applied directly to the spine through minimally invasive procedures, and early trials have shown remarkable recoveries in patients with paraplegia and quadriplegia. Some regained full mobility, while others saw significant improvements in trunk control and motor function.
While the results are promising, the drug is still awaiting regulatory approval from Brazil’s health agency (Anvisa) before it can be widely distributed. Hospitals in São Paulo are already preparing to begin treatment once authorized.
What are your thoughts on this potential breakthrough? How could regenerative medicine change the future of healthcare?
