8. Pancreas Cancer Cells Infiltrating Among Collagen Fibers
Clusters of pancretic cancer cells (pink-red) infiltrate among the normal connective tissue fibers, which are made of collagen (light green to white). The nuclei of the cancer cells are black, forming dark inclusions of varying sizes within the cell clusters. Many nuclei are quite enlarged and bizarre.
(Note: this enhanced high-power picture, produced by fluorescence microscopy, is able to show the irregularities and aggressive growth patterns of pancreas cancer cells better than conventional microscopic images.)
