Spontaneous mammary tumors from nulliparous and parous BALB/c-mice were stained with anti-ERα antibodies. Representative sections are shown for mammary intra-epithelial neoplasias (MIN) and adenocarcinomas that differ in ERα status. The tissues from nulliparous mice include ERαMIN, ERαadenocarcinoma, and ERαadenocarcinoma. The tissues from parous mice include ERαMIN, ERαadenocarcinoma, and ERαadenocarcinoma. Scale bar = 20 μm. ERα, estrogen receptor-alpha.<p><b>Copyright information:</b></p><p>Taken from "Estrogen and progesterone induce persistent increases in p53-dependent apoptosis and suppress mammary tumors in BALB/c-mice"</p><p>http://breast-cancer-research.com/content/10/3/R43</p><p>Breast Cancer Research : BCR 2008;10(3):R43-R43.</p><p>Published online 12 May 2008</p><p>PMCID:PMC2481490.</p><p></p
