An ear made from the person’s own cells was surgically attached in March, the company behind the technology says.

The University of Southern California bioengineer studies how lizards regrow their tails, with the goal of one day inducing regeneration in humans.

A new chemical treatment allowed African clawed frogs, which normally don’t regenerate limbs, to regrow functional hind legs following amputation.

The mice, already known to regenerate skin, seem to avoid the tissue scarring that leads to organ failure in other animals.

Understanding this complex and still largely enigmatic process will pave the way for researchers to control the development of new morphologies.

Understanding biology’s software—the rules that enable great plasticity in how cell collectives generate reliable anatomies—is key to advancing tissue engineering and regenerative medicine.

Planarian flatworms grow to double their normal size when scientists inhibit a gene that suppresses growth.

Physicists, geneticists, computer scientists, and biologists are working together to gain a full appreciation of the intricacies of organismal growth and form.

A study in mice reveals that stem cell transplants, currently in clinical trials, may not actually require the cells.

Collagen inside ankles has more turnover than that in hips, thanks to the action of microRNAs.

The funding future is uncertain for researchers studying topics including cancer, stem cells, and the Arctic.

The FTC, in its first crack down on the industry, gets two California companies selling unproven treatments to stop their false advertising and pay a fine.

Researchers recovered the cells that give rise to bone and cartilage from fetal and adult bone marrow and also derived them from induced pluripotent stem cells.
