Study Description

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. The secondary objective is to use patient tumor biopsy samples or circulating tumor cell samples to develop additional preclinical models of GU cancers, particularly prostate cancer, that are clinically relevant by generating additional PDXs.
