Figure 5. Crypt cell apoptosis.
Wild type (WT) and EGFR-null mice (VC(+)) underwent either 50% proximal small bowel resection (SBR) or sham operation (transection and reanastomosis of the bowel alone). On post operative day 7, the ileum was harvested and apoptotic bodies were counted in H&E sections of ileum. An apoptotic index was derived from the number of apoptotic bodies per 100 crypts. N=6-11 per group, ** = p < .005.
