생쥐에서 환자 유래 암세포의 정형외피 이식은 진행성 대장암을 재현합니다.

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.

Key Study Components

Area of Science

• To enhance understanding of metastatic processes in colorectal cancer.

Methods Used

• Implantation of patient-derived cancer cells in mice.
• Use of immunodeficient mice to support tumor growth.
• Extraction and dissociation of tumors for analysis.
• Maintenance of tumor samples in PBS for further experimentation.

Main Results

• The model successfully recapitulates advanced metastatic disease.
• Therapeutic evaluations can be conducted in this model.
• Insights into tumor biology and metastasis are gained.
• The model demonstrates potential for future research applications.

Conclusions

• The orthotopic model is a valuable tool for colorectal cancer research.
