7.4 POJA-L1945+204
Title: Mammary gland in pregnancy (human)
Description: Stain: (A) Hematoxylin –eosin, (B) Azan.
(A): Increased amount of dilated terminal ductules or acini (alveoli) filled with lipid-rich secretion. Note numerous lymphoid infiltrations between several acini.
(B): High magnification of cross-sectioned acini containing luminal lipid-rich secretion in the epithelium. At (arrows) few myoepithelial cells on the inner site of the BM). Blue-stained basement membranes between the acini.
Background: Milk contains proteins (casein, a-lactalbumin, parathyroid hormone-related proteins), lipids (triglycerides, cholesterol), lactose and IgA (from plasma cells in surrounding stroma of acini). Prolactin stimulates secretion by alveolar cells.
Keywords/Mesh: breast, mammary glands, pregnancy, histology, POJA collection, acini, myoepithelial cells.
