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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
