Figure Lengend Snippet: Mammary glands from lactating (5 days) mice of dab2 heterozygous controls and mosaic knockouts ( dab2 (f/df):Meox2-Cre) were analyzed by confocal immunofluorescence microscopy for several endocytosis and polarity markers. Where possible, markers were compared between Dab2-positive and Dab2-negative cells in the same section of the mosaic dab2 -deleted tissues. ( A ) Adaptin alpha and Dab2 double staining of mammary glands from a mosaic dab2 -deleted mouse, comparing Dab2-positive (arrow) and negative (arrowhead) cells; ( B ) Clathrin and Dab2 co-staining of mammary glands from a mosaic dab2 -deleted mouse, comparing Dab2-positive (arrow) and negative (arrowhead) cells; ( C ) Dab2 and E-cadherin staining: E-cadherin is localized more in the cytoplasm in Dab2-deleted cells (arrowhead); ( D ) NPT2b, a sodium-phosphate cotransporter; and ( E ) PMCA2 ATPase, a calcium pump, in Dab2-positive (arrow) and negative (arrowhead) cells. The results are the representation of multiple slides from 3 control (wildtype and heterozygous) and 3 dab2 conditional knockout mice.
