This image shows a colon tumor derived from APC flox/flox;Villin-Cre mice, a genetic model that specifically deletes the tumor suppressor APC in intestinal epithelial cells, leading to spontaneous tumor formation. The red fluorescence marks the tumor epithelium, while the green signal highlights eosinophils that have migrated into and interacted with the tumor microenvironment.

The vivid contrast between the red tumor core and the green immune infiltrates captures the dynamic crosstalk between epithelial transformation and immune regulation. The image not only represents a powerful model of colorectal cancer but also visually embodies the coexistence of destruction and defense—where immune cells engage tumors in a complex dialogue that shapes disease progression.
