Scientists Discover Gene Set That Could Enable Human Limb Regeneration
Researchers have identified a set of genes that may one day allow humans to regrow limbs, a breakthrough in regenerative medicine. The study, published in the Proceedings of the National Academy of Sciences, involved scientists from Wake Forest University, Duke University, and the University of Wisconsin-Madison. They studied axolotls, zebrafish, and mice, which are known for their regenerative abilities. The research focused on two genes, SP6 and SP8, which were found to be crucial in the regeneration process across these species. Using CRISPR technology, the team demonstrated that removing these genes hindered limb regeneration in axolotls and mice. The study suggests that these genes could be targeted in future therapies to promote limb regeneration in humans.
