Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

How do stem cells know what to become? Nearly three decades after scientists isolated the first human embryonic stem cells, researchers are still working hard to understand precisely how a single, ...

Researchers have developed a technique to connect lab-grown neural 'organoids' (three-dimensional developmental brain-like structures grown from human stem cells) using axonal bundles, similar to the ...

In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new ...

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body. Led by ...

The gene editing tool known as CRISPR-Cas9 is changing what's possible for treating a wide range of diseases caused by ...

CHICAGO (Reuters) - U.S. researchers have found a way to coax human embryonic stem cells to turn into the types of cells that make eggs and sperm, shedding light on a stage of early human development ...

A protein involved with cell death can be manipulated to slow or reverse tumor growth, a pair of new studies in mice found.
