简介：
Overview
This protocol describes the generation and characterization of murine oral-esophageal 3D organoids that model normal, preneoplastic, and squamous cell carcinoma lesions. These organoids serve as a platform for studying esophageal squamous cell carcinoma (ESCC) and its molecular changes.
Key Study Components
Area of Science
- Neuroscience
- Oncology
- Cell Biology
Background
- Esophageal squamous cell carcinoma (ESCC) is a prevalent and deadly cancer worldwide.
- 3D organoids can accelerate research in ESCC.
- Single cell-derived organoids capture the genetic diversity of tumors.
- These models are useful for testing new therapeutic strategies.
Purpose of Study
- To create a model that mimics ESCC for research purposes.
- To understand the molecular changes during ESCC initiation and development.
- To provide a platform for functional annotation of these changes.
Methods Used
- Utilization of 4NQO to induce ESCC in mice.
- Isolation of single cell-derived 3D organoids.
- Characterization of organoids for functional studies.
- Preparation of organoids for paraffin embedding.
Main Results

- They provide a relevant physiological model for testing therapies.
- Demonstrated techniques for organ collection and preparation.
- Facilitated understanding of tumorigenesis in ESCC.
Conclusions
- 3D organoids are valuable tools for ESCC research.
- They help elucidate the molecular mechanisms of cancer development.
- This model can aid in the identification of therapeutic targets.
What is the significance of using 3D organoids?
3D organoids provide a more physiologically relevant model for studying cancer compared to traditional 2D cultures.
How are the organoids generated?
Organoids are generated from single cells derived from mice treated with 4NQO, which induces ESCC.
What are the applications of these organoids?
They can be used to test novel therapeutic strategies and study the genetic changes in ESCC.
Who contributed to the study?
Yasuto Tomita and Norihiro Matsuura contributed to the demonstration of organ collection and preparation techniques.
What is the main focus of this research?
The main focus is to understand the molecular changes associated with ESCC using a 3D organoid model.
Why is ESCC a significant health concern?
ESCC is prevalent and has a high mortality rate, making it a critical area of research in oncology.
