Sidney: "Imagine a car accident victim who has major injuries or a patient who
has just had a piece of skin containing a cancerous lesion removed. The
surgeon places our tropoelastin mesh on the wound and it not only
instructs the wound how to repair, it helps accelerate the healing. It
could reduce the need for hospital stays and for skin grafts". Pr Tony Weiss,
from the University of Sydney, is describing the amazing potential of a
biomedical technology which mimics tropoelastin, the self-assembling
elastic protein which allows the body to repair elastic tissues in the
skin, artery, bladder and lung.
Development of the synthetic
version of the protein that Professor Weiss and his collaborators have
created has received a $1 million Wellcome Trust Translation Fund Award.
"Tropoelastin
is a building block of human biology and the more we learn about how it
assembles then the greater the range of applications we can achieve. We
are replicating human tissue and its behaviour - by making it in the
laboratory and not by extracting it from a living organism," said
Professor Weiss who is from the University's Charles Perkins Centre and School of Molecular Bioscience.
"Its
potential to benefit the sick and injured, from cardiac and cancer
patients to accident victims, from burns victims to wounded children, is
incalculable."
"This program enables us to fast-track the
technology to clinical trials within two years. The Wellcome Trust is
known for funding research which is revolutionary not evolutionary -
they look for projects that can leap from the lab to helping people,
with immediate and major benefits."
It took Professor Weiss and
his collaborators over fifteen years of work to tame this 'wild animal'
of the protein world. They eventually succeeded in painstakingly
producing milligrams of synthesised elastin and successfully
transitioning this process to industrial scale, enabling them to produce
kilograms.
He is also the founding scientist of the pioneering medical company Elastagen,
whose product development, based on tropoelastin, ranges from
dermatology and scar remodelling to tissue repair and surgical implants
and glues.
Through separately funded research, Professor Weiss
and his colleagues continue to explore additional applications of the
tropoelastin protein, including how to repair and build blood vessels
and other elastic tissues.
Last month they also received a
National Health and Medical Research grant of $587,000 to develop an
adhesive elastic bone filler that uses tropoelastin. It sets at body
temperature and rapidly restores mechanical performance at fracture
sites.
"Australian researchers are sometimes discouraged by the
'tyranny of distance' being a hurdle to attracting major overseas
funding so the fact we are now being supported by two overseas grants,
at the same time as receiving Australian funding, is heartening," said
Professor Weiss.
Funding for Professor Weiss's research includes
grants from the National Institutes of Health in the USA, the Australian
Research Council, National Health and Medical Research Council and
Cooperative Research Centre.
In addition to funding received from
NSW Health and the Wellcome Trust, Elastagen has received investment
from GBS Venture Partners and Brandon Capital Partners and has been
supported by both state and federal government programs, including the
NSW Health Medical Device Fund.
