By combining stem cell science with orthopedic surgery, a team of researchers at the University of British Columbia and Vancouver Coastal Health Research Institute aims to reduce the 10 per cent failure rate in hip replacements and make repeat replacements and other joint repairs obsolete within 10-15 years.
With $1.5 million over five years in funding from the Canadian Institutes for Health Research, a group of seven UBC scientists will explore how stem cells – the bodys "master cells" that can reproduce and develop many mature functional cells – can be used to regenerate bone cells to better secure artificial joints and other bone replacement structures. "Were very excited about the potential for long-term success for patients who need repeat surgery to repair or replace bone," says Fabio Rossi, UBC assistant professor of medical genetics and Canada Research Chair in Regenerative Medicine. "By using a well-understood stem cell and available technologies, we can accelerate research and have our discoveries quickly incorporated into patient care."
The team will create a new fixative mixture that combines minerals and slow-release growth factors. The mixture will be seeded with the patients own mesenchymal stem cells – a type of stem cell that is easily extracted from adult bone marrow and capable of manufacturing bone cells and connective tissue. This "living glue" will form a strong, organic environment to secure artificial joints, vertebrae or other replacement structures where the original replacement has failed.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
