Decellularized tissues as platforms for digestive system cancer models.

Area of Science:

• Biomedical Engineering
• Oncology
• Tissue Engineering

Background:

• The extracellular matrix (ECM) is crucial for cellular functions and tissue support, but its composition changes significantly in pathological conditions like cancer.
• Tumor cells alter the quantity and makeup of the surrounding ECM, highlighting its importance in the tumor microenvironment.
• Existing 2D and 3D models attempt to replicate tumor microenvironment complexity, but native ECM complexity remains a challenge.

Purpose of the Study:

• To review and summarize existing 3D models of digestive system cancers that utilize decellularized extracellular matrix (ECM).
• To highlight the potential of ECM-based scaffolds in studying cell-environment interactions within the tumor microenvironment.
• To provide insights into the pathophysiology of cancer through advanced modeling techniques.

Main Methods:

• Review of scientific literature focusing on 3D cancer models.
• Analysis of decellularized tissue-derived ECM scaffolds for cancer research.
• Summarization of studies employing these models for digestive system cancers.

Main Results:

• Decellularized ECMs serve as effective scaffolds that mimic the native tissue complexity.
• These 3D models facilitate the study of intricate cell-ECM interactions in cancer.
• The review consolidates current approaches to ECM-based 3D modeling for digestive cancers.

Conclusions:

• 3D models based on decellularized ECM offer a promising platform for investigating cancer.
• These advanced models can improve our understanding of the tumor microenvironment and cancer progression.
• Further development and application of ECM-based scaffolds hold potential for novel cancer therapies and diagnostics.
