Associate Professor, Medicine and Medical Sciences
Sean Lal is an Associate Professor (Research and Teaching) in the School of Medical Sciences in the Faculty of Medicine and Health at the University of Sydney. He is also a Consultant Cardiologist in the Department of Cardiology at Royal Prince Alfred Hospital, where he is the Director of Acute Heart Failure Services.
Our basic and translational research focuses on the human heart. We aim to investigate the molecular basis of cardiomyopathies, cellular changes in ageing, and intrinsic mechanisms of cardiac regeneration.
We uniquely draw on tissue from The Sydney Heart Bank (SHB), which contains over 20,000 cryopreserved human cardiac samples from our collaborations with St Vincent's Hospital (Sydney), the Australian Red Cross Donor Service and Royal Prince Alfred Hospital.
We have developed an extensive tissue database and international research network with the common goal to further our understanding of human heart failure.

The Sydney Heart Bank (SHB)
Overview
In 1989, in collaboration with the late Dr. Victor Chang AO, Prof. Cris dos Remedios established the Sydney Heart Bank (SHB) at the University of Sydney to collect and store explanted human hearts for research purposes. The SHB now comprises over 18,000 human cardiac samples from explanted failing hearts and non-diseased donor hearts from patients at St Vincent's Hospital Sydney. The SHB has now expanded to prospectively procure heart, aortic, and vascular samples from patients at Royal Prince Alfred Hospital under the directorship of Sean Lal, together in collaboration with Paul Bannon and Jacky Loa.
The SHB is not-for-profit and collaborates with over 30 research laboratories within Australia and around the world. The independent external research projects are in conjunction with our own in-house projects. The research projects range from examining cardiac regeneration, contractile mechanics cellular and molecular cardiology, cardiac proteomics, vascular diseases, and aortopathies.
We gratefully thank the support of the Faculty of Medicine and Health at the University of Sydney, and the Baird Institute for Heart and Lung Research in maintaining the infrastructure, staffing, and operations of the SHB. We acknowledge the patients and staff of St. Vincent's Hospital Sydney and Royal Prince Alfred Hospital.

Before you apply
Please provide the following documents at the time of requesting tissue:
1. Two-page project proposal. This proposal will need to satisfy the follow criteria:
2. Two-page CV/biosketch
3. Human Research Ethics Committee (HREC) approval letter from your local institution with start and end dates
Application process overview
1. Lodge a request for tissue. This must include the proposal, CV and HREC approval.
2. The documents will be assessed by members of the scientific review board.
3. If approved, the SHB will generate a Material Transfer Agreement between the two institutions.
4. The SHB will then arrange to transport at the cost of the receiving institution
Sydney Heart Bank User Policy
Any and all biological samples from the SHB must
1. Always be stored in liquid nitrogen (liquid or vapour phase)
2. Not be re-coded in any form
3. Not be used for project other than that specified in the Human Research Ethics Committee (HREC) Approval and Material Transfer Agreements.
4. Not be exchanged between institutions without pre-acknowledgement and agreement from the SHB
5. To be returned to the SHB if unused
All publication outputs (including conferences) must
1. Acknowledge and identify HREC approval from the Sydney Heart Bank and the recipient’s local institution
2. Use the original de-identified code provided by the SHB. This information enables published data to be shared between laboratories working on tissue from the same patients.
