BRIEF TITLE: Reconstitution of a Human Immune System in a Patient Derived Xenograft (PDX) Model of Genitourinary (GU) Cancers

Reconstitution of a Human Immune System in a Patient Derived Xenograft (PDX) Model of Genitourinary (GU) Cancers

Brief Summary

The objective of this study is to obtain human blood CD34+ hematopoietic stem/progenitor cells (HSPCs) to reconstitute a match human immune system in our PDX model. The hypothesis is that by using matched leukocytes and PDX from the same patient, rejection of the PDX by the host immune system will not be observed and therefore a preclinical model to study immunotherapy can be developed to study, understand and improve upon our current therapies. HSPCs will be collected from bone marrow aspirate obtained from a bone marrow biopsy.
