How do PDX models differ from conventional models?

PDX models are derived directly from patient tumors, maintaining their original characteristics, while conventional models often involve established cell lines that may lose critical attributes over time.

What therapeutic areas benefit most from PDX models?

Oncology is a primary area benefiting from PDX models, but they can also provide valuable insights into other therapeutic areas where tumor biology is complex, such as neuroscience and rare diseases.

When should researchers consider using PDX models?

Researchers should consider PDX models during preclinical development when investigating new therapeutic agents, particularly when custom responses are essential for drug efficacy prediction.
