Adult Stem Cells Migrate to Lung, Contribute to Pulmonary Fibrosis

04.08.2004


Findings: UCLA researchers for the first time identified and then stopped a type of adult stem cell from migrating to the lung and contributing to pulmonary fibrosis in an animal model. Pulmonary fibrosis (i.e, idiopathic pulmonary fibrosis) in humans is a devastating terminal disorder that causes an overabundance of scar tissue to form in the lung.

Impact: The new study may offer novel therapies to treat idiopathic pulmonary fibrosis– currently there are no effective treatments and the mortality rate is approximately 70 percent within five years of diagnosis. Over 80,000 individuals in the United States suffer from the disease.

Authors: Dr. Robert M. Strieter, study senior author and Chief of the Division of Pulmonary and Critical Care Medicine, and Vice Chair of the Department of Medicine at the David Geffen School of Medicine at UCLA, is available for interviews.



Journal: The research appears in the August 2 edition of the peer-reviewed Journal of Clinical Investigation. A PDF of the full study is available.

Background: Previously it was thought that idiopathic pulmonary fibrosis was due to resident fibroblasts/myofibroblasts located in the lung, according to Strieter. “We now have evidence that a specific adult stem cell travels to the lung through the bloodstream where it then can produce collagen that leads to the scar tissue formation.” Using an animal model, researchers also showed that the mechanism causing the adult stem cell to travel to the lung could be blocked, thus reducing the amount of collagen build-up in the lung and reducing pulmonary fibrosis. Researchers will next further study the regulation of the expression of the receptor that is involved in the recruitment process of these cells.

Strieter notes that the new study may also provide insight into new treatments for other disorders, such as connective-tissue diseases (i.e., rheumatoid arthritis) and liver cirrhosis, which, like idiopathic pulmonary fibrosis, all are associated with an overabundance of scar tissue formation. The study is funded by the National Institutes of Health.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

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...

Im Focus: A Chip with Blood Vessels

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...

Im Focus: A Leap Into Quantum Technology

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...

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

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...
