Cell Deformability & Cell Adhesion

Series of microphotographs showing the micropipette experiment setup

Series of microphotographs showing the micropipette experiment setup.

Most of our work centers on the deformability of blood cells and how blood cell deformability plays a role in health and disease. We interested in what kinds of things can affect the deformability of cells and how changes in deformability affect the flow of blood and delivery of oxygen to living tissues. We use very small glass pipettes and glass fibers to apply measured forces to the surfaces of individual cells and we observe the deformation using a microscope with an attached television camera.

There are three main classes of blood cells:

  • red blood cells
  • white blood cells
  • platelets

Red blood cells carry oxygen and carbon dioxide to and from the tissues. They are the most numerous (and most easy to deform) of the cells and make up approximately 40-45% of the blood volume. Most of the rest of the blood volume is plasma, and white cells and platelets generally make up less than 1% of the volume.

Platelets are smaller than red cells and are involved in clotting. White blood cells come in a variety of types, and are important in fighting disease. The two most common white cells are neutrophils and lymphocytes. These are larger than red blood cells and deform more slowly than red blood cells.
