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 ...

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 ...

How do stem cells know what to become?Nearly three decades after scientists isolated the first human embryonic stem cells, researchers are still ...

A set of lab-grown stem cells could hold the secret to a game-changing cancer treatment. So far, the cells have only been tested in mice, but when infused into the rodents, scientists say the stem ...

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