As if fat weren't troublesome enough, a research team at the University of Colorado School of Medicine has discovered a new type of fat cell with potentially harmful characteristics.
The new fat cells arise from stem cells in the bone marrow that travel through the blood stream to fat tissue. They are termed bone marrow progenitor-derived adipocytes. The discovery also revealed that male and female subjects accumulate the new fat cells differently. The research also may help to explain the link between types of obesity and heart disease and other illnesses.
The findings by Dwight J. Klemm, PhD, and Susan M. Majka, PhD, are reported this week in the Proceedings of the National Academy of Science of the United States of America.
"Our results explain why the accumulation of fat in certain body locations harms health," Klemm said.
According to Majka, the research "may identify ways to prevent those adverse effects as people age or gain weight."
The body stores energy in fat – either white or brown cells. But over time too much fat can cause health issues. Previously, the researchers at the University of Colorado Anschutz Medical Campus had traced certain fat cells back to bone marrow. It appeared likely that a type of stem cell (the hematopoietic cell) was getting into the blood stream and settling somewhere else.
The latest research, which used laboratory mice but applies to humans, demonstrates that is the case. It shows that these stem cells travel through the blood stream into fat tissue and tend to accumulate in deep abdominal fat, primarily of females. This new type of fat may affect the body's ability to dispose of fats and sugars, and produces inflammatory problems. The results also help explain why fat in different parts of the body behaves differently. The research team now is detailing the health threats these fat cells cause and looking for ways to halt the formation and accumulation of harmful fat.
Faculty at the University of Colorado's School of Medicine work to advance science and improve care. These faculty members include physicians, educators and scientists at University of Colorado Hospital, The Children's Hospital, Denver Health, National Jewish Health, and the Denver Veterans Affairs Medical Center. Degrees offered by the School of Medicine include doctor of medicine, doctor of physical therapy, and masters of physician assistant studies. The School is located on the Anschutz Medical Campus, one of four campuses in the University of Colorado system. For additional news and information, please visit the UC Denver newsroom online.
The University of Colorado Anschutz Medical Campus is a model for the type of interdisciplinary research in translational medicine that will take basic discovery "from the bench to the bedside."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
