Scientists Discover Stem Cells That Could Regenerate Teeth and Bone  SciTechDaily Source link

Scientists have grown embryo-like structures in the laboratory that produced human blood cells, raising new possibilities for regenerative medicine. The ability to generate blood stem cells in the laboratory may one day make it possible to treat patients in need of bone marrow transplants using their own cells. The advance is the latest in a rapidly advancing field in which …

Scientists have created a new and more advanced form of immune-based cancer therapy using engineered cells known as CAR-NK (natural killer) cells. Like CAR-T cells, these modified immune cells can be programmed to recognize and attack cancer, but they rely on a different type of immune cell that naturally targets abnormal or infected cells. A team from MIT and Harvard …

Summary: Researchers have identified a rare type of brain cell that may drive the chronic inflammation and neurodegeneration seen in progressive multiple sclerosis (MS). These cells, called disease-associated radial glia-like (DARG) cells, appear six times more often in patients with progressive MS than in healthy individuals. DARGs revert to an early developmental state yet also show premature aging, releasing inflammatory …

Scientists at McGill University and the Douglas Institute have discovered that two distinct types of brain cells show changes in people experiencing depression. Published in Nature Genetics, the research provides new clues that could guide the creation of treatments focused on these specific cells. It also enhances scientific understanding of depression, a condition that affects more than 264 million people …

Summary: Scientists have discovered a group of brain cells in the orbitofrontal cortex that become more active when outcomes are uncertain, revealing how the brain adapts and learns from unpredictable situations. These neurons—found in both rats and humans—help balance flexibility and precision in decision-making, particularly when rewards are inconsistent. When these cells were inactivated in rats, learning performance declined, suggesting …
