A pathologist examines a thin slice of tissue with a microscope and notes
numerous cells packed tightly together. No intercellular space or blood
vessel is noted between cells, but the cells have polarity. One side of the
cells opens into a cavity, and the other is attached to a thin layer of
extracellular material. Several of the cells are in some stage of mitosis.
