Moreover, the distribution pattern of SLUG (green) was similar with that of β-catenin (red) and more yellow fluorescence signals were observed (Fig. 2a) than that within tissues stained with TWIST (green)/β-catenin (red) (Fig. 2b) or SNAIL (red)/β-catenin (green) from the CRS group (Fig. 2c). Here, SNAI1 is linked to congenital rubella syndrome.
