From: PTHrP induces STAT5 activation, secretory differentiation and accelerates mammary tumor development
PTHrP maintains the expression of activated STAT5 and delays involution. H&E (A) and immunohistochemical analysis (B) of mammary glands from lactation day 12 (Lac12) and involution day 3 (Inv3) glands from Tet-PTHrP mice on Dox versus off Dox as controls. A Bars represent mean ± SEM of the area occupied by adipose and alveolar tissue in 10 random fields. B Bars represent mean ± SEM of the percentage of pStat5 positive cells in 5 random fields (average of 2200 cells per gland). Representative images from each group are shown. N = 3, Scale bar 100 µm
