(April 25, 2016) — A long-standing question in biology is why humans have poor regenerative ability compared to other vertebrates? While tissue injury normally causes us to produce scar tissue, why can't we regenerate an entire digit or piece of skin? A group of University of Kentucky researchers is one step closer to answering these questions after studying a unique mammal, and its ears.
The team's new findings come on the heels of UK Assistant Professor of Biology Ashley Seifert's landmark discovery in 2012 that two species of African spiny mice found in Kenya could regenerate damaged skin. The group built on this work to show that a third species of spiny mouse, Acomys cahirinus, could
