The Xenograft Core is dedicated to establishing and expanding patient-derived xenograft models generated from donated pediatric tumor tissue. Our goal is to serve as a resource for molecularly characterized xenograft tumor models freely distributed to requestors both internally and outside the institution via the Childhood Solid Tumor Network and the Neurobiology Brain Tumor Program.

The lab provides services for the handling, processing, propagation and storage of solid tumor and brain tumor specimens. The four full time core personnel have expertise in murine injections, biological sample collection and clinical observations of xenograft tumor models.

Xenografts provide valuable support for investigators studying pediatric solid tumors and brain tumors. Xenografts help establish common themes across distinct diseases and are essential in preclinical testing of novel therapeutics which can drive new effective treatment strategies in the clinic. The Xenograft Core offers over 300 different models and over 35,000 tumor samples, with a myriad of tumor histologies and disease stages.
