Certain types of cells from fat tissue can repair skull defects in mice, say researchers at Stanford University Medical Center. Because this type of healing process does not depend on the use of embryonic stem cells or gene therapy, it may one day allow doctors to use a patient’s own unmodified cells as building blocks to heal fractures, replace joints, treat osteoporosis or correct defects in bone growth or healing.
"These cells are from you, for you and by you," said Lucile Packard Children’s Hospital pediatric craniofacial surgeon Michael Longaker, MD. "They are not foreign and they don’t express foreign genes. To our knowledge, this is the first time these cells have ever been shown to have a therapeutic effect." Longaker, a professor of surgery at Stanford’s School of Medicine, is the senior author of the research, published in the May issue of Nature Biotechnology.
"Fat is a great natural resource," he added. "These cells are not only easily harvested, they grow quickly in the laboratory." In contrast, bone marrow cells and bone cells, both of which can also repair skull damage, grow very slowly outside of the body.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

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...
