Mouse model of colorectal cancer: Orthotopic co-implantation of tumor and stroma cells in cecum and rectum

Abstract

interrogation of the functional role of genes implicated in colorectal cancer (CRC) is limited by the need for physiological models that mimic the disease. Here, we describe a protocol that provides the steps required for the orthotopic co-implantation of tumoral and stromal cells into the cecum and rectum to investigate the crosstalk between the tumor and its microenvironment. This protocol recapitulates metastases to the lymph nodes, liver, and lungs observed in human CRC. For complete details on the use and execution of this protocol, please refer to Kasashima et al. (2020).
