Mosaic β-gal staining patterns in 21OH/LacZ transgenic fetal and postnatal adrenal glands from E14.5 to P21 and adult. Typical mosaic β-gal staining patterns seen in longitudinal mid-sections of 21OH/LacZ adrenal glands at (A) E14.5 (not sexed), (B) E16.5 (not sexed), (C) E17.5 female, (D) E18.5 female, (E) P1 female, (F) P3 female, (G) P5 female, (H) P7 female, (I) P10 female, (J) P14 female (K) P21 female, (L) adult female (13 weeks). Adrenal glands were frozen-sectioned and stained for β-gal activity as described in Materials and Methods. Males and females were analyzed separately from E17.5 and showed similar patterns of β-gal staining at each stage studied, so only results for females are illustrated. Dark areas in the photographs were stained blue (β-gal-positive). Scale bars = 200 µm.
