A 'stemness checkpoint' helps control stem cell identity

A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...

Cell 'snowball' may be answer to large-scale tissue engineering

Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures ...
