Left: Phase contrast image of H9 stem cell colony, highlights indicate the types of measurements that can be derived from an image. Middle: The same colony imaged in fluorescence, cells are expressing GFP under the control of the Oct4 promoter. Right: Apple tree on NIST campus that is a direct descendant of the tree that provided Newton inspiration.
