FIGURE 2.
ISH mammary gland sections from pregnant mice. Panels illustrate mammary gland sections hybridized with no probe (top; negative control), Zfas1 antisense probe (middle), and Zfas1 sense probe (bottom; negative control). Images in dotted boxed areas increase in magnification from left to right. The arrows show ductal and alveolar structure and the expression of Zfas1 within these structures. Scale bars in each panel are indicated. The genomic context of the ISH probe is shown in Supplemental Fig. S3.
