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

Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different process.

Geckos injected with neural stem cells modified to block cartilage growth developed the skeletal and nervous components normally lacking from regrown tails.

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

While regeneration has long been the domain of colonial tunicates, a solitary species of sea squirt was able to regenerate into multiple, fully functional individuals within a month of being cut up.

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.

A study finds similarities between cells that heal wounds and those that lead deadly cancerous invasions.

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.

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

Scientists have manipulated the electrical signals that help guide flatworms in regenerating their body parts to encourage a flatworm to grow two heads.

The eel-like lamprey can return to normal swimming and burrowing after suffering a severed spinal cord twice.

At magnetic field intensities somewhat above that of Earth, stem cell proliferation shifts gears.
