Introduction Xenograft models are versatile platforms for investigating diverse cancer types, each presenting unique challenges in tumor biology, therapeutic targeting, and translational predictivity. Comparative analyses across tumor types highlight how
Introduction One of the most pressing challenges in oncology is the emergence of therapy resistance. Even when initial responses are robust, tumors frequently recur in more aggressive, treatment-refractory forms. Xenograft
Introduction Patient-Derived Xenografts (PDX) have redefined translational oncology by directly linking preclinical research to clinical decision-making. Beyond their role in drug discovery, PDX models are increasingly employed in co-clinical trials,
Introduction Xenograft models have transformed preclinical oncology by providing in vivo systems that retain many biological and molecular features of human tumors. Yet, long-term use of these models introduces significant
Introduction Traditional xenograft models provide valuable insights into tumor biology and therapeutic efficacy but are fundamentally limited in their ability to evaluate immunotherapies. Since immunodeficient murine hosts lack functional adaptive
Introduction Intratumoral heterogeneity is a defining feature of human cancers and a primary driver of therapeutic resistance. Conventional in vitro models fail to capture the dynamic interplay between co-existing subclones,
Introduction Patient-Derived Xenografts (PDX) represent one of the most translationally relevant in vivo cancer models available to preclinical research. By directly implanting tumor fragments harvested from patients into immunodeficient mice,
Introduction Xenograft models are indispensable tools in oncology research, providing a physiologically relevant in vivo platform to study tumor biology, evaluate therapeutic responses, and bridge the translational gap between preclinical
Plymouth Meeting, PA – August 2025 – Cancer remains one of the greatest health burdens worldwide. Preclinical models are indispensable for developing therapies that can effectively translate from the laboratory
