This research aims to understand how cancer cell programs influence interactions with the tumor microenvironment.
Generated mouse xenografts from 19 human colorectal cancer cell lines.
Performed RNA sequencing for human and murine transcriptomes.
Analyzed the correlation between tumor growth rates and stromal abundance.
Characterized transcriptional programs and identified the EMT-Matrix Remodeling signature.
Slower-growing colorectal tumors accumulated more stroma, correlated with worse prognosis.
Cancer cells exhibited a coordinated EMT and ECM remodeling program.
Identified a matrix-remodeling CAF signature in corresponding stromal fibroblasts.
EMR and mrCAF signatures linked to aggressive disease across various tumor types.

Implication

Xenograft analysis reveals that slow-growing colorectal cancers recruit fibroblasts to reshape the tumor environment, indicating a mechanism of cancer progression.
