  • Blood cells through the microscope. This image is a combination of what can be seen through the microscope, and the artists impression of blood cells and surrounding structures and organisms.
  • Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels (string-like structures). A network of lymphatic vessels (ribbon-like structures) is also present. In this image, human skin lymphatic vessels (stained for LYVE-1; blue) and white blood cells comprised of dendritic cells (stained for CD11c; green) and T cells (stained for CD3; red) can be seen. Some macrophages also express the protein LYVE-1 similar to lymphatic vessel cells which can be appreciated as blue cells within and in between the sheaths of white blood cells. This normal cellular architecture is grossly disrupted in diseased skin (see related images). X10 magnification. Scale bar (white) represents 200 micrometres.
  • Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels. In this image, blood vessels (string-like structures stained for CD31; green), lymphatic vessels (ribbon-like structures stained for LYVE-1; blue) and T cells (stained for CD3; red) can be seen. T cells are only found around dermal blood vessels. Macrophages (stained for LYVE-1; blue) are also present. This normal cellular architecture is grossly disrupted in diseased skin (see related images). X10 magnification. Scale bar (white) represents 200 micrometres.

  • Liver of a DEN (Diethylnitrosamine)-treated rat. DEN is a toxic chemical which quickly induces liver cirrhosis followed by HCC (Hepatocellular carcinoma, a primary liver cancer). Cirrhosis is an end result of fibrosis, the scarring of liver tissue. Fibrosis is caused by the overproduction of collagen, a component of the connective tissue forming the liver. To grade the amount of cirrhosis present in a liver sample, collagen is made visible using the dye sirius red. Under polarized light, collagen is observed as the golden to red color as shown in this image.
