New Technique Dissects Stem Cells' Picky Likes, Dislikes

...(ECM). These interactions with surfaces play a key role in stem cell growth and differentiation. And that got Kiessling thinking. "If we want to control stem cell fates," she says, "maybe we could start to create surfaces of defined molecules, put stem cells down on them, and ask, 'What happens?'" To...

Preserving Kidneys on a Pump May Promote More Organ Sharing

... said machine preservation has played an important role in the Medical Centers success transplanting kidneys at the outer limits of the ECD acceptance criteria, such as organs donated after cardiac death, preserved for more than 30 hours, or from donors over age 70.

Life Expectancy Increased by Eating Less

...ch team found that the gene called 'pha-4' plays a role in gut development in embryonic worms, but in adults is associated with calorie-restricted longevity. Scientists say humans do have three genes very similar to pha-4. These genes say the researchers are related to glucagon, a pancreatic hormone tha...

Brains White Matter: More Talkative Than Once Thought

...oligodendrocyte precursor cells (OPCs), whose main role when they mature into oligodendrocytes is to wrap themselves around and insulate nerves with a whitish coat of protective myelin. The immature cells simply hang around and divide very slowly, waiting to be spurred into action. To learn more about O...

British Scientists Discover New Protein to Treat Epilepsy and Schizophrenia

The scientists who discovered SUMO's role say it is interesting because it means the receptor is not destroyed, but simply lies dormant, meaning the dangers of completely cutting off communication between cells should be avoided. Professor Jeremy Henley, who led the research, said: "We hav...

Cataloging the Structural Variations in Human Genetics

...We know there is a genetic factor, but what is the role of single base pair changes versus structural changes? The project Eichler and his colleagues describe in their paper will help answer this question. Using DNA from 62 people who were studied as part of the International HapMap Project, they are c...
