Research description

The Cambridge Blood and Stem Cell Biobank is a facility of over 6000 viable and nucleic acid samples, the majority from patients with haematological malignancy and clonal blood cell disorders; and the remainder, around 20%, from normal individuals, mostly umbilical cord blood. The Biobank was established in 2009, and supports research in the the University Departments of Haematology and Medical Genetics, the Sanger Institute, and their collaborators. Since its inception, the biobank has played an active role in supporting research with significant input into high impact publications. We have transferred over 2000 samples to local researchers in the past 5 years, including over 500 cord blood samples, with a strong emphasis on high quality material for next generation sequencing technologies and cell assays. The aims of the biobank in the coming years are to expand collection of patient samples to cover all types of haematological malignancy, to consolidate all samples collected since 1992 by local researchers into a fully searchable sample and clinical data resource, and to raise the profile of research with patients and visitors to the site.
