Supplementary Notes

This file contains Supplementary Methods and Supplementary Figure Legends.

Supplementary Figure 1

Smad4-dependent signaling is in stroma cells is key to maintaining intestinal homeostasis.

Supplementary Figures 2 and 3

Supplementary Figure 2 details diffuse plasma cell infiltration of intestines in mice with T cell-restricted deletion of the SMAD4 gene. Supplementary Figure 3 details epithelial-specific expression of a dominant-negative acting Smad4 transgene is not associated with spontaneous tumorigenesis.

Supplementary Figure 4
