Currently, kidney disease affects up to 20% of the US population and is a strong contributor to morbidity and mortality in these patients. Specific therapies and diagnostic tools for kidney disease have been very slow to develop because of the absence of high quality samples and data that can be used for research studies. The purpose of this study is to develop a registry and sample bank called Poseidon (Prevention, Optimizing Safety, Early Intervention and DetectiOn in Nephrology) biobank that can be used for future research. In this study, patients can consent to donating their residual kidney tissue if they undergo a kidney biopsy and blood or urine during routine clinical care procedures. We will also collect blood and urine outside of clinical care.This study will allow biomedical research the ability to obtain specimens from patients with relevant diseases and appropriate clinical data. This study will collect patient demographic, clinical and historical data for a registry and patient samples will be deposited in the Poseidon biobank. Patients do not have to be diagnosed with Kidney Disease to be included in this study.

The primary purposes of this study are to:
•Provide access to cord blood units for recipients whose best choice for a cord blood unit(s) do not meet all FDA standards, but do meet standards set by the NMDP on this study.
•Assess how well and how quickly blood counts return to normal after transplant in recipients on this study.
