Human tissue models in cancer research: looking beyond the mouse

Area of Science:

• Oncology
• Translational Research
• Biomedical Science

Background:

• Mouse models, including patient-derived xenografts, are standard in cancer research but exhibit flaws misrepresenting human tumor biology.
• These limitations hinder the translational value of animal models for clinical applications.
• Current research faces challenges in accurately modeling human cancer due to inherent differences between species.

Discussion:

• Non-animal human tissue models present a clinically relevant alternative, maximizing the utility of human tissue resources like biobanks.
• Barriers to adoption include inadequate infrastructure for tissue handling and a cultural reliance on established animal models.
• Overcoming these obstacles requires addressing data compatibility concerns and fostering a shift towards innovative research methodologies.

Key Insights:

• Developing and utilizing non-animal human tissue models can provide a more accurate platform for cancer studies.
• Addressing infrastructure deficits and promoting collaborative initiatives are crucial for the widespread adoption of these models.
• Standardizing biobanking practices and quality control are essential for reliable human tissue research.

Outlook:

• Coordinated efforts in data sharing and collaboration can accelerate the development and implementation of human tissue models.
• Integrating these models into research practices promises to enhance cancer drug discovery pipelines.
• Reducing dependence on potentially less predictive animal models will improve the efficiency and success rate of translational cancer research.
