Researchers Created Structures That Produced Blood Cells in the Lab—With a Process That Mimics Real Human Embryos

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

Tightening the focus of subcellular snapshots: Combined approach yields better cell slices for cryoET imaging

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...
