The mouse mammary gland consists of milk-producing alveolar cells and a network of ducts that transport the milk to the nipple. Beginning at puberty, ducts grow out from the nipple, invading the surrounding fat pad. Many of the factors important in development of the mammary gland may also be involved in breast cancer initiation and in subsequent tumor growth. In each image, ducts branch into the surrounding fat pads. The colors have been changed in each rendering.
