Immune system fighting a cancer cell. A killer T-lymphocyte (orange) inducing a cancer cell to undergo Programmed Cell Death.
Lymphocyte. Coloured scanning electron micrograph (SEM) of a lymphocyte white blood cell. Lymphocytes are involved in the immune system's defence mechanisms, lymph system, and involved in antibody production.
Renal corpuscle of kidney. The renal corpuscle is formed by the glomerulus (red), in the glomerulus blood is filtered.
Granulocytic white blood cells (neutrophil), T-lymphocytes, and a red blood cell (erythrocyte).
Cells are constantly on the move. They shift, grow, and migrate to new locations—for example, to heal a wound or to intercept an infectious agent as part of an immune response. But how do cells actually move?
This is an actual picture of White Blood Cells, in with some red blood cells. The platelets are stained purple, a T-Lymphocyte white cell is stained green, and a Monocyte white cell is stained gold as seen through a scanning electron microscope.
Lung tissue, coloured scanning electron micrograph (SEM). At upper centre is a capillary filled with red blood cells (erythrocytes) and surrounding it are alveolar ducts. Alveolar ducts are the narrowed endings of bronchioles that open into clusters of alveoli (air sacs, not seen). Magnification: x555 when printed 10 centimetres high.

Cancer cell division. Coloured scanning electron micrograph (SEM) of two prostate cancer cells in the final stage of cell division (cytokinesis). During this stage the cells’ cytoplasm divides. Here the cells are joined by a thin cytoplasmic bridge. Cancer cells divide rapidly in a chaotic, uncontrolled manner. They may clump to form tumours, which invade and destroy surrounding tissues.
