Graphic: Professor David Lo with a student [11/07/2014] Research in the UCR School of Medicine laboratory of David Lo found that certain cells of the epithelium have a potentially important role in immune surveillance – creating an electrostatic repulsion field to microbial invasion.Study reveals protective role for specialized cells - Read more

Blocking cells' movement to stop the spread of cancer

Graphic: cell [10/07/2014] Insights into how cells move through the body could lead to innovative techniques to stop cancer cells from spreading and causing secondary tumors, according to new UCL research. Scientists discovered that cells can change into an invasive, liquid-like state to readily navigate the narrow channels in our body. Blocking cells' movement to stop the spread of cancer - Read more

Graphic: a microscope with which DNA is examined [09/07/2014] A research team at the Faculty of Medicine & Dentistry at the University of Alberta have discovered a new way by which metabolism is linked to the regulation of DNA, the basis of our genetic code. The findings may have important implications for the understanding of many common diseases, including cancer.Metabolism is linked to the regulation of DNA - Read more

Cultured skin makes large-scale transplantations possible

[01/07/2014] Large burns require skin grafting. Surgeons remove split-thickness skin grafts and apply them to the injured areas. Now skin that has been made in a laboratory is meant to help in covering burns as well as chronic wounds and thus promote the healing process. Researchers in Zurich have been working on this for more than 13 years.Cultured skin makes large-scale transplantations possible - Read more

Diagnosing Parkinson’s: the skin is revealing

( Source: MEDICA.de )

[01/07/2014] In patients with Parkinson’s, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient’s death, and not during his or her lifetime.Diagnosing Parkinson’s: the skin is revealing - Read more

Fat is the best medicine: ”Adipose tissue contains many multipotent stem cells, approximately 500 times more than bone marrow“

[01/07/2014] The not so popular “love handles“ could revolutionize medicine in the near future. In cooperation with the University of Rostock (Professor Hermann Seitz), the human med AG Company currently seeks to develop a device that is able to gently remove adipose tissue during surgery and subsequently isolate stem cells.

An international team of researchers under the direction of scientists from the Institute of Innate Immunity at the University Hospital of Bonn has discovered how this incredible form of communication works.Immune system: not even cell death can stop the alarm - Read more

Photo: Eye overlaid with transparent images [10/06/2014] In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people, the researchers say.Making artificial vision look more natural - Read more
