Area of Science:

Biomedical research
Cell biology
Drug discovery

Background:

Traditional preclinical models (2D cell culture, animal models) have significant limitations.
2D cultures lack in vivo disease heterogeneity and physiological relevance, leading to drug trial failures.
Animal models present ethical concerns, high costs, and xenogeneity.

Purpose of the Study:

To introduce three-dimensional (3D) organoid models as an advanced alternative for preclinical research.
To highlight the potential of organoids in disease modeling and drug screening.
To address the challenges and future directions in organoid research.

Main Methods:

Utilizing human tissue-derived organoids for 3D cell culture.
Self-organization of organoids into tissue-specific structures.
Application of organoids in disease modeling and high-throughput drug screening.

Main Results:

Organoids recapitulate the complexity and function of their tissue of origin.
Organoid models show improved relevance for predicting drug efficacy compared to traditional models.
Organoids demonstrate potential for advancing cancer pathophysiology and immunology studies.

Conclusions:

Organoids represent a significant advancement over 2D cell cultures and animal models in preclinical research.
Further integration with bioengineering approaches may overcome current organoid research challenges.
Organoid technology holds promise for more accurate disease modeling and effective drug development.
