Immunocharacterization of transcription factors in Prop1 transgenic adenomas. Light microscopy of coronal sections of a wild-type mouse pituitary (WT; a) and Prop1 Tg mice including PRLoma (b), Prop1 Tg including GHoma (c), Gn-PRLoma/GH-PRLoma (d) and small TSHoma (e). Immunostaining of Pit1, ERα, Gata2 and H&E stain. Arrowhead: Gata2 expression in the nucleus of small TSHoma region, Asterisk: adenoma region. Bars=50 µm.
