The Progress and Clinical Application of Breast Cancer Organoids

Area of Science:

• Oncology
• Biotechnology
• 3D Cell Culture

Background:

• Breast cancer is a leading malignancy in women.
• Current in vitro models like cell lines and patient-derived xenografts (PDX) have limitations in accurately representing human tumors.
• A need exists for more physiologically relevant breast cancer models.

Purpose of the Study:

• To review the development, sources, culture systems, and clinical applications of breast cancer organoids.
• To highlight breast cancer organoids as an advanced in vitro model.

Main Methods:

• Patient-derived tumor cells are cultured in three dimensions.
• Cytokines are added to promote proliferation and inhibit apoptosis of breast cancer stem cells.
• This process forms in vitro organoids mimicking in vivo tumor structures.

Main Results:

• Breast cancer organoids provide a more accurate in vitro representation of tumor structure and biology compared to traditional models.
• Organoids facilitate the study of breast cancer occurrence and evolution.
• The model shows promise for high-throughput drug screening, personalized treatment strategies, toxicity testing, and immunotherapy research.

Conclusions:

• Breast cancer organoids represent a significant advancement in modeling this disease in vitro.
• Their clinical potential for drug development and personalized medicine is substantial.
• Further research and application of organoid technology are crucial for improving breast cancer care.
