Professor Xu and his team study the
mechanisms that cause development of heart and circulatory diseases
in order to understand how they can be treated. They particularly
focus on the build up of fatty materials in the
walls of the arteries (atherosclerosis).
Stem cells and blood vessel diseases
Recent evidence indicates that stem cells (cells that can
transform into many different types of specialised cells) play a
crucial role in the development of heart disease and
atherosclerosis. Professor Xu is looking at the potential use of
these cells in developing treatments. Very recently the team found
that artery walls contain abundant stem cells which we could
perhaps harness for disease prevention or therapy.
Professor Xu's work with stem cells is a vital part of our
Mending Broken Hearts campaign. We're
looking to spend £50m to help people with heart failure following a
heart attack.
Proteins and genes
In order to harness this potential for future
therapies, we need to understand the signals that spark the
transformation of stem cells into functional cells carrying out
specific jobs in our blood vessels.
These signals come in the form of proteins and Professor
Xu’s group is working to reveal these important molecular
signals by profiling all the proteins present in stem cells
and specialised blood vessel cells.
Understanding bypass failure
Professor Xu's team has created a vital
model to replicate the build up of fatty plaques (atheroma) in
heart bypass vein grafts. This is proven to be powerful for
studying the development and treatment of bypass failure, which
occurs in about half of vein grafts within a decade of the
procedure.
Many people from Europe and the USA have
visited Professor Xu’s laboratory to learn the techniques for
establishing the model, which is now used widely. In addition, the
team also use several other models for their studies, including
heart transplantation.
