The Leukemia Tissue Bank Shared Resource (LTBSR) helps scientists translate basic research to the clinical setting by providing central collection, processing and storage of tissue samples from patients with leukemia, myeloma or lymphoma enrolled on Ohio State University Comprehensive Cancer Center – James Cancer Hospital and Solove Research Institute (OSUCCC – James) protocols. These samples are available to investigators at Ohio State and to outside collaborators who study the cellular and molecular properties of these diseases. The ability to examine tumor cells from patients is an essential part of determining the causes of cancer and developing new and effective treatments.
