Abstract
Source: Kochall, S., et al. Isolation of Circulating Tumor Cells in an Orthotopic Mouse Model of Colorectal Cancer J. Vis. Exp. (2017)
The video describes the technique for intracecal injection of cancerous cells to develop an orthotopic mouse model with highly uniform tumors. Therefore, the orthotopic mouse model allows realistic simulation of metastasis, providing a valuable tool to study the phenotype changes during tumor growth and dissemination.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation of cell lines for injection NOTE: Use a volume of 20 µL with 100,000 cells for each injection. Use basement membrane matrix (BMM) to prevent leakage and ensure standardized injection. To ensure reproducible results, conduct cell line authentication assays (e.g.,&#…
