Diabetes Drug Could Prevent Scarring Through Targeting Fibroblasts

Scientists have long wondered the necessity of scars to the body's healing process; when we are injured, why can't our skin just regenerate back to the way it looked previously? Why do we have to carry such an unsightly reminder of the past, sometimes in visible places we don't want others to see? While some may see scars as the symbol of the healing process, others see them as a cosmetic burden.

Dr. Michael Longaker, co-director of the Institute for Stem Cell Biology and Regenerative Medicine at Stanford University, sought to uncover the mystery behind scars, and whether they are necessary.
