"Harvard Scientists' Breakthrough Paves Way for Human Limb Regeneration"

Harvard University scientists, in collaboration with Kyushu University, have made significant progress in the research of limb regeneration by reprogramming fibroblast cells to mimic limb progenitor cells, which are responsible for limb development in embryos. The team successfully identified a group of genes that, when introduced to fibroblast cells, caused them to take on the properties of limb progenitor cells. While the process has not yet been applied to human cells, the researchers believe it is a significant step toward the goal of helping humans regrow lost limbs and are working to replace the method used to inject genetic information into the cells to reduce the risk of cancerous growth.
