Expression of NDST-2 mRNA by +/+ and

tg/tg skin mast cells but not bymi/mi skin mast cells. A section of +/+,mi/mi, or tg/tg skin was stained with alcian blue and nuclear fast red, and the adjacent section was hybridized with the antisense probe for the NDST-2 gene. Another section of +/+,mi/mi, or tg/tg skin was stained with alcian blue and nuclear fast red, and the adjacent section was hybridized with the sense probe for the NDST-2 gene. Identical mast cells in the pairing sections are shown by arrows (original magnification × 400).
