Modeling neoplastic disease with spheroids and organoids

Area of Science:

• Oncology
• Biotechnology
• Preclinical Research

Background:

• Cancer development involves genetic defects and microenvironmental factors, complicating treatment.
• Traditional 2D cell cultures inadequately represent complex tumor architecture and patient-specific disease.
• Three-dimensional (3D) models offer a more accurate in vitro representation of human tumors.

Purpose of the Study:

• To review recent advancements in 3D cancer models (spheroids and organoids).
• To highlight the translational applications of these models in drug discovery and personalized medicine.
• To compare 3D models with traditional animal models in preclinical cancer research.

Main Methods:

• Utilizing spheroids and organoids to recapitulate cancer heterogeneity and pathophysiology.
• Modeling dynamic cancer evolution and microenvironment interactions in vitro.
• Evaluating 3D systems for drug discovery, personalized medicine, and preclinical research.

Main Results:

• 3D models like spheroids and organoids closely mimic the in vivo tumor microenvironment and architecture.
• These models facilitate the study of cancer biology, from early stages to metastasis.
• 3D systems show promise in enhancing the reliability of preclinical data and reducing animal testing.

Conclusions:

• Spheroids and organoids represent versatile and promising tools for cancer research.
• The use of 3D models can bridge the gap between in vitro and in vivo studies.
• Advancements in 3D systems offer innovative translational applications for improved cancer treatment strategies.
