Xenopat offers the most innovative tools available to progress the development of new oncologic drugs. Xenopat offers researchers and drug developing companies the OrthoXenoBank®, which is composed of several orthoxenografts®, orthotopic models of different tumor types, including among others colorectal, lung, breast, ovarian, testicular and pancreatic tumors. Orthoxenografts® are characterized at histological and genetic level, with different sensitivity to diverse chemotherapies. The Advanced Preclinical Services of Xenopat aim at becoming a strategic partner through the entire oncologic drug development process: from the basic preclinical steps, up to commercialization. Thus, Xenopat’s Advanced Preclinical Services can become a useful tool to make informed decisions both in preclinical phases and in clinical trial phases, even in post-commercialization stages.

Orthoxenografts® are experimental mouse models in which a small piece of human tumor is implanted (implantation from one spices to another, xenograft) in the same organ of origin (orthotopically).


The OrthoXenoBank® is the collection of orthoxenografts® that Xenopat can offer to its customers.
