Exam 17: Beyond the Cell: Cell Adhesion, Cell Junctions, and Extracellular Structures

You discover a dog suffering from a strange disorder that has been found to be due to an autoimmune response against its own cells. Upon further investigation, you find that the cells of various tissues are loosely arranged and do not have characteristic shapes, and that the animal is prone to hemorrhage as the result of poor blood clotting.
