regeneration

Fish fins and single-cell sequencing help scientists glean new insights into tissue regeneration.

Removing excess iron from aging mouse blood-forming cells enhances their regenerative capacity.

A metabolic pathway used for tail regrowth may be critical for tissue regeneration in some cells, a study suggests. 

Unlike other fast-growing cells, regenerating tadpole cells fuel growth using the pentose phosphate pathway rather than glycolysis, a study indicates.

Mycobacterium leprae appeared to reprogram the animals’ livers to a state partially resembling early development, resulting in healthy organ growth.

Mice that received the stem cell–derived treatment were less frail compared with controls, a study reports.

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

How stem cells in human teeth respond to different environmental conditions offers clues for regenerative medicine.

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.
