UNIVERSITY OF COPENHAGEN THE FACULTY OF HEALTH AND MEDICAL SCIENCES Stem cells all share the potential of developing into any specific cell in the body. Many researchers are therefore trying to answer the fundamental questions of what determines the cells’ developmental fate as well as when and why the cells lose the potential of developing into any cell. Now, researchers from the Novo Nordisk...

Study: Phenols in cocoa bean shells may reverse obesity-related problems in mouse cells
UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN, NEWS BUREAU CHAMPAIGN, Ill. — Scientists may have discovered more reasons to love chocolate. A new study by researchers at the University of Illinois suggests that three of the phenolic compounds in cocoa bean shells have powerful effects on the fat and immune cells in mice, potentially reversing the chronic inflammation and insulin resistance associated with obesity. Visiting scholar in food...

Scientific discovery may lead to a treatment for lupus
By Dr. Liji Thomas, MD When there is an excessive number or hyperactivation of immune cells, very high levels of proteins known as cytokines are released, resulting in a cytokine storm that causes severe and often irreversible tissue damage. This accounts for the crippling nature of many autoimmune disorders such as lupus. Now, an international team of...

Blood stem cells produced in vast quantities in the lab
A glue ingredient was the secret to getting the mouse cellsto multiply outside the body. Researchers have managed to grow large numbers of blood-forming stem cells in the lab using a surprisingly simple ingredient found in glue. And when injected into mice, the cells started producing key components of blood. “The finding is very unexpected and...

Mitochondria come together to kill cancer cells
Uncovered details of a molecular pathway in cancer cells could lead to improved treatment. Targeting a pathway that controls the movement of mitochondria, the powerhouses of all cells, could reduce cancer invasiveness and resistance to radiotherapy.

Electric fields: cancer killers?
Pulsing cells with electric fields can force calcium diffusion into cells. Researchers have now optimized this technique in an attempt to kill cancer cells and leave healthy cells intact. Researchers from the Bioelectrics Department of Kumamoto University (Japan) have identified the optimal pulsed electric field (PEF) conditions for the maximum calcium cell membrane permeability. There...
