简介：
Overview
This protocol describes the orthotopic implantation of patient-derived cancer cells in the cecum wall of immunodeficient mice. This model recapitulates advanced colorectal cancer metastatic disease, allowing for the evaluation of new therapeutic drugs in a clinically relevant scenario of lung and liver metastases.
