Dośluzówkowa inokulacja komórek raka płaskonabłonkowego u myszy w celu profilowania immunologicznego guza i oceny odpowiedzi na leczenie

Overview

This article presents a reproducible method for developing an orthotopic murine model of head and neck squamous cell carcinoma. The model exhibits clinically relevant histopathological features and symptoms similar to those observed in human patients.

Key Study Components

Area of Science

• Oncology
• Neuroscience
• Pathology

Background

• Head and neck cancers are increasingly prevalent.
• Understanding the tumor microenvironment is limited.
• Mechanisms of treatment resistance in head and neck tumors are not well understood.
• This model recapitulates the native microenvironment of these tumors.

Purpose of Study

• To develop a method for creating a murine model of head and neck squamous cell carcinoma.
• To study the tumor microenvironment and treatment resistance.
• To observe clinical manifestations similar to those in humans.

Methods Used

• Cell culture techniques for tumor cell preparation.
• Orthotopic implantation of tumor cells in mice.
• Monitoring of tumor growth and clinical symptoms.
• Histopathological analysis of tumor samples.

Main Results

• Developed tumors show necrosis and poor differentiation.
• Presence of nodal metastases and immune infiltration.
• Clinical symptoms include dysphagia, jaw displacement, and weight loss.
• The model effectively mimics human disease characteristics.

Conclusions

• The orthotopic murine model is a valuable tool for studying head and neck squamous cell carcinoma.
• This model can aid in understanding treatment resistance mechanisms.
• It provides insights into the tumor microenvironment and clinical manifestations.
