The eclectic Biology of the Mammary Gland site is aimed at developmental biologists, cancer researchers, and physiologists. The site, from Lothar Hennighausen's lab at the National Institute of Diabetes and Digestive and Kidney Diseases, includes everything from technical tips to pathology slides, mainly on mice.

A histology atlas brims with images of normal and unhealthy tissues. Visitors can track development of the mammary glands in mice from birth to pregnancy and compare the process in, say, mice lacking the estrogen receptor. Pages on techniques explain how to prepare and stain tissue, insert genes into mammary cells, and more. The reviews section includes slide shows, short backgrounders, and audio lectures on topics such as the physiology of milk secretion and breast cancer diagnosis. Above, branching milk-producing ducts from a 4-week-old mouse.
