Researchers determined that when introduced into damaged mouse or donated human livers, these lab-grown tissues could integrate into bile ducts and function normally.

New twists to an old technique reveal a better understanding of disease pathology and new therapeutic avenues.

Infusions of donor T cells to fight the cancer often fail, but sodium bicarbonate can counter lactic acid produced by leukemia cells, potentially improving remission rates in mice and humans.

A proof-of-concept study uses a strategy similar to the way tumors evade immune detection. The new limbs survive for more than 200 days.

Researchers can print cells and biomaterials that make up human tissues, but there’s still a long way to go before fully functional organs can be made to order.

Several early-stage clinical trials indicate that implanting patients with the cells is safe. But whether they can alleviate neurological problems remains to be seen.

The patient’s vision has improved since the procedure, and her cornea remains clear.

Scientists are devising human-animal hybrids for harvesting human organs, but lab-derived mini-organs are a less ethically fraught solution to meeting the need for transplantation.

Insulin-producing cells grown in the lab could offer a functional cure for the disease.

Primates receiving heart transplants from genetically engineered pigs have survived more than six months, a new study reveals.

Blind rats are made to see after sheets of cells implanted into their eyes make themselves at home.

An investigation finds regenerative medicine researcher Suchitra Sumitran-Holgersson manipulated data in seven papers.

Doctors treated the fetus, who has alpha thalassemia major, with cells from her mother’s bone marrow.

The woman’s own cartilage was used to construct the transplant after she lost her left ear in a car crash.

After losing his genitals in a roadside bomb explosion, the soldier endured a 14-hour surgery to have a donated penis, scrotum, and partial abdominal wall attached.

After implantation, the tissue developed blood vessels and became integrated into neuronal networks in the animals’ brains.

Gender discrimination, Brexit, and climate change are among the issues that have received considerable attention from the scientific community this year.

The group calls for the retraction of six publications by surgeon Paolo Macchiarini regarding the synthetic trachea transplantations that led to the death of at least three patients. 

Using human stems cells and segments of rat intestines, scientists engineer bowels that are capable of absorbing nutrients.
