Fibroblast cell, coloured scanning electron micrograph (SEM). Fibroblasts are cells that give rise to connective tissue such as collagen, the main structural protein in the body. Magnification: x2000 when printed at 10 centimetres wide.

Coloured scanning electron micrograph (SEM) of Candida albicans infected medical catheter. A common yeast, C. albicans can colonize catheters resulting in serious tissue infections. Shown here is the inner surface of an infected catheter (removed from...
