Breast: pregnancy
This high magnification image of the connective tissue of the breast during pregnancy shows the accumulation of plasma cells, which secrete antibodies of the IgA class into the milk. These antibodies provide passive immunity to the newborn child. Other cells typical to connective tissue are also visible. 1000x
