Studying the process of brain formation illuminates just how much of development is a series of tiny miracles. Only a few weeks after a human egg is fertilized, a sheet of cells called the neural ...

We’ve come a long way from the Vacanti mouse. Back in the mid-90s, Charles Vacanti and other researchers experimented with cartilage regeneration and, with the help of a biodegradable mold and bovine ...

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production ...

In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their ...

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...
