Guess the Cover of American Laboratory—May 2012

The image on the cover of the May issue of American Laboratory was provided by Dr. Fred E. Hossler, Professor Emeritus, Dept. of Anatomy & Cell Biology, Quillen College of Medicine, East Tennessee State University, Johnson City, TN. The sample, provided by a local dermatology clinic, was captured using a Zeiss DSM 940 scanning electron microscope. Using routine SEM, the original magnification of this sample was 200x. The image has been artificially colored using Photoshop.
