Abruptly involuted glands are exposed to prolonged steroid hormone signaling. a Representative images of GI and AI mammary gland sections harvested on day 7 (d7, lactating gland), day 28, and day 56 postpartum and immunostained for ERα. H-score of ERα-positive cells in the epithelium and stroma is quantified in the bar diagram (n = 3, scale bar = 100 μM). b Representative images of GI and AI mammary gland sections harvested on day 7, day 28, and day 56 postpartum and immunostained for PR (n = 3, scale bar = 100 μM). Epithelial PR stain is quantified in the bar diagram. Error bars represent standard error of the mean. Linear mixed models were used to calculate significance
