Three-dimensional (3D) in vitro models accurately mimic bladder tissue and tumor microenvironments for studying bladder cancer (BC). These advanced models, including organoids and spheroids, are valuable tools for drug screening and hold potential for clinical applications.
Area of Science:
- Biomedical Engineering
- Oncology
- Tissue Engineering
Background:
- Bladder cancer (BC) is a significant genitourinary malignancy, classified as non-muscle invasive (NMIBC) or muscle-invasive (MIBC) based on tissue layer involvement.
- Current treatments for NMIBC and MIBC involve surgery and chemotherapy, but novel therapeutic strategies are needed.
- In vitro models are crucial for understanding BC and testing new treatments, with 3D models offering enhanced biological relevance.
Purpose of the Study:
- To review and summarize recent advancements in the development of 3D in vitro bladder models.
- To highlight the utility of these models in mimicking bladder tissue and tumor microenvironments.
- To discuss the potential of 3D bladder models for drug screening and clinical translation.
Main Methods:
- Review of current literature on 3D in vitro bladder model development.
- Analysis of various 3D model platforms including spheroids, multilayer models, organ-on-chip, bioprinting, and organoids.
- Evaluation of the ability of 3D models to replicate bladder tissue and tumor microenvironment complexity.
Main Results:
- 3D in vitro bladder models effectively recreate the morphology, complexity, and function of native bladder tissue and tumor microenvironments.
- These models facilitate the study of cell-cell and cell-extracellular matrix interactions, crucial for understanding BC progression.
- Platforms such as organoids, spheroids, and hydrogels are established as effective drug screening tools.
Conclusions:
- 3D in vitro bladder models offer a more accurate representation of in vivo conditions compared to traditional 2D cultures.
- These models serve as valuable preclinical tools for evaluating drug efficacy and permeability.
- 3D bladder models demonstrate significant potential for future clinical applications in bladder cancer research and treatment.
