This is Tatiana Sampaio, a Brazilian scientist who restored movement to six paraplegic patients. The Nobel Prize in Medicine is the bare minimum 🇧🇷 After more than twenty years dedicated to scientific research, Brazilian biologist Tatiana Coelho de Sampaio gained international recognition by leading a groundbreaking study on spinal cord injuries. A professor at the Laboratory of Extracellular Matrix Biology at UFRJ (Federal University of Rio de Janeiro), she coordinates the development of polylaminin, an experimental molecule that opens new perspectives for the treatment of people with paraplegia and tetraplegia caused by accidents. The substance is a laboratory-produced version of laminin, a protein essential in embryonic development for guiding communication between neurons. Created from proteins extracted from the human placenta, polylaminin can be applied directly to the injured area of ​​the spinal cord, promoting the regeneration of nerve circuits and the recovery of previously compromised motor functions. Even though it is still in the experimental phase, the initial results have attracted the attention of the scientific community. Some patients undergoing the treatment have shown partial or even complete recovery of movement and sensation, something considered unlikely by conventional medicine. There are records of volunteers who regained movement in affected limbs after the procedure. The project is being developed in partnership with the Brazilian laboratory Cristália and already has investments to advance to the next stages. The goal now is to obtain authorization from Anvisa (Brazilian Health Regulatory Agency) to expand clinical studies and evaluate, on a larger scale, the safety and efficacy of the therapy.
