What if humans could regrow tissue? New study moves science closer

For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But new research from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) suggests that this limitation may not be permanent. Instead, the capacity for regeneration may still exist—hidden within the body's normal healing process.
