Lab-grown ‘ghost hearts' work to solve organ transplant shortage by combining a cleaned-out pig heart with a patient’s own stem cells
Scientist Doris Taylor explains how she and her team are creating bioengineered human hearts in their lab with the goal of one day eliminating the need for heart transplants.

A new treatment helped frogs regenerate their amputated legs – taking science one step closer to helping people regrow their body parts, too
Unlike humans, many animals are able to regenerate their limbs after losing them. Giving the body the right conditions for regrowth might allow people to recover lost limbs as well.

Wyss researchers has electrifying insights into how bodies form
A researcher is reviving the study of bioelectricity to learn how cells communicate with each other to form tissues and organs, and how harnessing those signals could one day lead to truly regenerative medicine, in which amputees could simply regrow limbs.

Scientists find new type of cell that helps tadpoles’ tails regenerate
Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These ‘Regeneration-Organizing Cells’ help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues.

Lungless salamanders’ skin expresses protein crucial for lung function
A recent study shows that a gene that produces surfactant protein c — a key protein for lung function — is expressed in the skin and mouths of lungless salamanders, suggesting it also plays an important role for cutaneous respiration.
