George Murphy wants to use stem cells to replace scarring with regenerative healing.

• George Murphy’s goal is to coax skin stem cells into healing wounds by regenerating tissue instead of forming a scar.
• To figure out how to do it, he is studying scarless healing during fetal development and “stem cell burnout” during aging.
• Insights into scarless healing will help research into regenerating other vital organs, including the heart.

Press release of the Massachusetts General Hospital

Using human induced pluripotent stem cells (iPSCs), a Massachusetts General Hospital (MGH) research team has bioengineered functional small intestine segments that, when implanted into rats, were capable of deliver nutrients into the bloodstream. The investigators describe their accomplishment in the online journal Nature Communications.

“In this study we have been able to bridge the gap between differentiation of single cells – driving stem cells to become a specific cell type – and the...
