Figure 300 from Chapter 11 (Melanin Pigment) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Conjunctival epithelium from the limbal region of the eye of the Macaca mulatta. Clusters of melanosomes donated from melanocytes (not present in this micrograph) are contained within the epithelium. Intercellular spaces are filled with horseradish peroxidase, injected intravenously, permeating the epithelium and outlining the cells. Image by Giuseppina Raviola.
