It's a longstanding mystery why salamanders can perfectly regenerate their tails whereas lizard tails grow back all wrong. By transplanting neural stem cells between species, researchers have discovered that the lizard's native stem cells are the primary factor hampering tail regeneration.

E-cigarette vapour disables important immune cells in the lung and boosts inflammation.

Scientists discovered that boosting mice's cholesterol levels spurred intestinal stem cells to divide more quickly, enabling tumors to form 100 times faster. The study identifies a molecular pathway that could serve as a new drug target for colon cancer treatment.

A drug used in stem cell therapy to treat certain cancers may also protect against cigarette smoke-induced lung injury.

A new therapy developed through stem cell technology holds promise as a treatment for chronic asthma.

In a study of over 50 transcription factors, Tbx6 alone was able to stimulate mesoderm formation in laboratory-grown stem cells, and could cause those stem cells to become cardiovascular or musculoskeletal cells. Researchers found that this essential role of Tbx6 in mesoderm and cardiovascular specification is conserved from lower organisms to mammals. This research report validated a new direct reprogramming-based approach that may enhance future regenerative medicine research.

Stem cells in the skin remember an injury, helping them close recurring wounds faster, researchers have found. The discovery could advance research and treatment of psoriasis and other inflammatory diseases.

Find out what gives our bones their remarkable ability to heal breaks in a finely tuned process that involves stem cells, cartilage, and bone.
