Findings may aid diagnosis and indicate new treatment target for many cancers
A new study from Columbia University Medical Center finds that stomach (gastric) cancer originates from bone marrow derived stem cells (BMDC), rather than from stomach stem cells, as previously thought. The study, "Gastric Cancer Originating from Bone Marrow-Derived Cells" is published in the current issue of Science. "This was an unexpected finding, which may lead to a re-evaluation of current assumptions about how all cancers originate," said Timothy C. Wang, M.D., chief, Division of Digestive and Liver Diseases and Dorothy L. and Daniel H. Silberberg Professor of Medicine at Columbia University College of Physicians and Surgeons and senior author of the study. "The implications of this study may lead to new methods of diagnosis and treatment of many cancers – particularly those that have been linked to chronic inflammation such as stomach, esophagus, lung, pancreas, liver, etc."
A common assumption among cancer specialists is that most cancers originate from tissue stem cells – for example, the gastric stem cells contained in the lining of the stomach. However, the researchers suspected BMDC may contribute to the development or progression of cancer because they are frequently recruited to sites of tissue injury and inflammation, e.g., a typical site for cancer development.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
