p63 and Satb1 Expression (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption At top, p63 proteins labeled pink and Satb1 proteins labeled green are expressed together in the nuclei of cells in a normal (wild-type) developing epidermis. At bottom, green-glowing Satb1 is abundant in the epidermis of a wild-type mouse, but in a mouse without the p63 gene, Satb1 is not expressed.
