Crypt cell proliferation is decreased in Gata6ΔIE mice. (A) Immunostaining in ileum for the proliferation markers Ki67 (top row) and BrdU (bottom row). (B) Quantification of Ki67- and BrdU-positive cells/crypt in each group. Cells were counted as described in Methods. Gata6Δ IE mice had significantly fewer Ki67- or BrdU-positive cells than each of the other three groups (P < 0.01 in each case), consistent with a decrease in crypt cell proliferation.
