Breast: pregnancy
This higher magnification of a lobule demonstrates its acini and the well-developed intralobular and interlobular ducts. Secretory product begins to accumulate in the lumens during late pregnancy. The intralobular connective tissue contains numerous mast cells and plasma cells. Plasma cells secrete antibodies into the milk. 100x
