Figure 4. Conditional deletion of β-catenin increases the occurrence of basal mitoses.
Staining for PH3 reveals mitotic cells in control βcatfl/fl/cre- and βcatfl/fl/cre+ cortex. Basal mitoses per mm of ventricular surface were increased in βcatfl/fl/cre+ cortices. Arrowheads highlight examples of basal PH3+ cells. Scale bars are 250 µm. * * = P<0.01, t test, two-tailed.
