CryoSTEM tomography of vitrified cells

CryoSTEM tomography (CSTET) is a method for probing the 3D structure of vitrified, intact cells, in regions up to 1 micron thick.  Pictured is a volume rendering of a small region of a human fibroblast cell, revealing mitochondria, cristae, ribosomes, vesicles and other cellular features and organelles.
