Figure 2.
Semi-quantitative analysis of changes in the mosaic β-gal staining patterns in 21OH/LacZ transgenic adrenal glands from E17.5 to P21. (A and B) changes in the contributions of different types of β-gal-positive staining to the overall mosaic pattern of the adrenal cortex with age in (A) female and (B) male 21OH/LacZ transgenic mice. (Bar charts A and B are shaded according to type of staining; see text for details). (C) Change in β-gal staining patterns in the adrenal medulla. (D) Change in β-gal staining patterns in the X zone. 21OH/LacZ adrenocortical β-gal staining was classified separately for left and right adrenals as described in Materials and Methods. The average scores for left and right adrenals are shown.
