The Duke Human Heart Repository began in earnest in 2008 as an investigator driven entity designed to address key questions of interest in the Milano/Bowles research program related to cardiovascular disease causes and treatments, and improvement of cardiac transplantation and mechanical circulatory support outcomes.
Our self-imposed mission statement is as follows:
- To collect and store cardiac and related tissues (blood derivatives plasma/serum), urine, and clinical information on subjects undergoing ventricular assist device implantation, heart transplantation, or other cardiac surgeries where discarded cardiac tissue is available.
- To make these tissues available to be used in future research studies by investigators internal and external to Duke.
Our specimens are now provided through collaborations to researchers in academia and industry all over the world in projects involving cardiovascular physiology, disease, bio-markers, and molecular targets for intervention as well as in secondary pharmacological testing of pharmaceutical agents in development.
Tissues are used for discovery and models:
- Flash frozen in liquid N2 and stored at -80°C.
- Embedded in OCT histology media
- Preserved in RNAlater
- Powdered frozen tissue
- Blood and urine
- Preservation solution
Specialized services based on our access to viable tissue:
- Primary cell isolation: cardiac fibroblasts, cardiomyocytes, cardiac progenitor cells
- Molecular Biology/viral vector gene delivery
- DNA/RNA isolation and purification
- Working heart perfusion (Langendorff)
- Isolated tissue bath
