Title: Regression of mammary gland after lactation (human)
Description: Stain: Azan.
(A): After cessation of lactation lobules regress, atrophy and are infiltrated by adipocytes (1). A single intralobular duct is still recognizable (2).
(B): Another area shows atrophying alveoli (3), few adipocytes (1), a dilated intralobular duct (2) and an extralobular duct (4).
Background: Following the cessation of lactation the mammary gland undergoes a tissue remodeling the so-called involution. The amount of glandular structures decreases and the adipose tissue compartment takes up a much larger proportion of the tissue. Regressive changes in mammary glands are induced by increasing levels of estrogens followed by reestablishment of the menstrual cycle.
Keywords/Mesh: breast, mammary glands, histology, POJA collection, lactation, regression, atrophy, adipocytes.
