Drug Discovery Goes Three-Dimensional: Goodbye to Flat High-Throughput Screening?

Area of Science:

• Biotechnology
• Cell Biology
• Drug Discovery

Background:

• Traditional two-dimensional (2D) cell cultures lack in vivo characteristics, contributing to high failure rates in clinical drug development.
• Limitations of 2D cultures necessitate more physiologically relevant models for accurate compound screening and lead optimization.

Purpose of the Study:

• To highlight the advancements and utility of three-dimensional (3D) cell culture techniques in modern drug discovery.
• To emphasize the potential of 3D models, including organoids and spheroids, for high-throughput screening in oncology.

Main Methods:

• Exploration of novel techniques in cell biology, materials science, and bioengineering for 3D cell culture.
• Application of 3D culture systems, from simple spheroids to complex organoids, compatible with automation.
• Integration of stem cells, such as induced pluripotent stem cells, into 3D models for enhanced phenotypic relevance.

Main Results:

• 3D culture methods provide more physiologically relevant cellular models compared to 2D cultures.
• These advanced models are increasingly compatible with automation for high-throughput and high-content screening.
• 3D cultures, especially when incorporating stem cells, offer potential for disease-specific screening.

Conclusions:

• Three-dimensional cell culture represents a significant advancement over 2D methods for drug discovery and development.
• The adoption of 3D culture techniques, including organoids and spheroids, is crucial for improving the success rates of drug candidates, particularly in oncology.
• Future applications may involve disease-specific screening using stem cell-derived 3D models.
