Modeling Cell Communication in Cancer With Organoids: Making the Complex Simple

Area of Science:

• Oncology
• Cell Biology
• Biotechnology

Background:

• Cell-to-cell communication is vital for multicellular organisms and significantly impacts tumor development.
• Cancer cells interact with the tumor microenvironment (TME) through various mechanisms, including physical contact, paracrine signaling, and extracellular vesicles (EVs).
• Effective experimental models are needed to study cancer cell-cell interactions and their role in disease progression.

Purpose of the Study:

• To discuss the potential of patient-derived organoids as a model system for studying cancer cell-to-cell communication.
• To highlight how organoids can recapitulate key features of human tumors, including genetic heterogeneity and TME interactions.
• To explore how organoid models can advance the understanding of cancer initiation and progression.

Main Methods:

• Reviewing existing literature on cell-to-cell interactions in cancer.
• Evaluating the advantages of organoid technology over traditional cell culture and animal models.
• Discussing the application of organoids in modeling the complex interplay within the tumor microenvironment.

Main Results:

• Patient-derived organoids faithfully mimic patient disease traits, including genetic diversity and therapeutic responses.
• Organoid cultures preserve the in vivo topology of cell-cell and cell-matrix interactions.
• Organoids have demonstrated success in studying interactions between cancer cells and TME components.

Conclusions:

• Organoids provide a valuable platform for modeling cancer cell-non-cancer cell interplay.
• This modeling can elucidate biological mechanisms driving cancer initiation and progression.
• Organoid research may lead to the identification of novel therapeutic strategies for cancer treatment.
