Summary
Integrating peripheral blood mononuclear cells (PBMCs) into organoids enhances disease modeling by recreating complex tumor microenvironments. This approach improves drug screening and personalized medicine applications.
Area of Science:
- Biomedical Engineering
- Cell Biology
- Immunology
Background:
- Organoids are 3D in vitro models mimicking in vivo tissues, crucial for disease modeling and drug screening.
- Conventional organoids lack native microenvironments, limiting their use in studying immune responses and immunotherapies.
- Peripheral blood mononuclear cells (PBMCs) are accessible, heterogeneous immune cells reflecting patient-specific immunity.
Purpose of the Study:
- To review advancements in integrating PBMCs into organoid models.
- To summarize PBMC properties and applications in various organoid systems.
- To compare modeling methodologies and discuss future directions for PBMC-integrated organoids.
Main Methods:
- Review of recent literature on PBMC-integrated organoid systems.
- Summarization of PBMC biological properties and applications.
- Comparative analysis of current modeling techniques.
Main Results:
- PBMCs are increasingly used to engineer immune-integrated organoid models.
- PBMC integration enhances organoid complexity, particularly the tumor microenvironment.
- Applications span cerebral, renal, pulmonary, and hepatic organoid models.
Conclusions:
- PBMC-integrated organoids offer improved platforms for studying immune-related diseases and evaluating immunotherapeutics.
- These models hold significant potential for personalized medicine and understanding disease mechanisms.
- Further research is needed to address limitations and optimize these advanced models.
