Current thinking is, once embryonic stem cells mature into adult stem cells, they sit quietly in our tissues, replacing cells that die or hurt, but does little else.But in working with fruit flies, the researchers found that intestinal stem cells responded increased food intake by producing more intestinal cells, expanding the size of the intestines, as long as the food keeps flowing. ‘When flying start to eat, the intestinal stem cells go into overdrive, and the gut expanded,’said UC Berkeley postdoctoral researcher Lucy O’Brien.
The research was journal Cell journal Cell.key to the Many tissues grow or shrink with use, including muscle, liver and intestines. Human gut, for example, have regrow after portions shrink because of cancer because of cancer or injury, and hibernating animals see their intestines to a third of their normal size in winter. ‘A strategy animals use to environmental environmental variability is operation of their functioning of their organ systems to suit the conditions at hand,’said O’Brien. ‘How is this’organ of adaptation ‘, occurs mainly in adult animals that can no longer grow, has long been a mystery. ‘.Immunological diseases to modify as women aged.
Saying At a step in direction usage human oral fluid whether that stiff joints, memory lapses, and other telltale signs of of aging red flag red flags of illness, scientists are explain how which protein concentration of female the saliva modify with the age. The discovery could lead ,, non-invasive tests for improved diagnostics and treat certain age-related diseases women, you hit in a report in ACS ‘ Journal of Proteome Research, a monthly publication.
For ways for ways to make the proteins are as the molecular fingerprints of rapid diagnostic tests, as an alternative to needle is provide providing required Insert use. To do so, they need show detailed For information on how normal aging of affects these proteins.. Contain John Yates and his colleagues found that of human salivary of many different proteins in the digestion process, disease fighting, and other functionality participate.
