Bioengineered in vitro three-dimensional tumor models in endocrine cancers

Area of Science:

• Oncology
• Endocrinology
• Biotechnology

Background:

• Endocrine tumors (thyroid, adrenal, neuroendocrine) are rare and heterogeneous, often resistant to conventional chemotherapy.
• Limited understanding of endocrine tumor biology hinders development of targeted therapies and immunotherapies.
• Traditional models (mice, 2D cultures) fail to fully recapitulate human endocrine tumor complexity.

Purpose of the Study:

• To review advancements in bioengineered 3D tumor models for endocrine tumors.
• To highlight the application of organoids and tumor-on-a-chip systems in endocrine oncology.
• To discuss the potential of these models for mechanistic exploration and therapeutic development.

Main Methods:

• Review of current literature on 3D bioengineered tumor models.
• Focus on applications in thyroid, adrenal, and neuroendocrine tumor research.
• Description of organoid and tumor-on-a-chip technologies.

Main Results:

• 3D models offer improved recapitulation of endocrine tumor heterogeneity and architecture.
• These advanced models are increasingly being applied to study specific endocrine tumor types.
• Emerging platforms show promise for overcoming limitations of traditional cancer models.

Conclusions:

• Bioengineered 3D models represent a significant advancement for endocrine tumor research.
• Organoids and tumor-on-a-chip systems are crucial for understanding endocrine tumor biology.
• These models will likely accelerate the development of novel therapeutic strategies for endocrine malignancies.
