Master regulatory gene of epithelial stem cells identified

...rge Higginson professor of cell biology at HMS, to show that p63’s key function was to provide the enhanced potential of stem cells to divide. "The fact that p63 is essential for these epithelial stem cells, while other master regulators have been identified for blood stem cells and spermatocyte stem...

Survival of the rarest: Fruit flies shed light on the evolution of behavior

... all species. The researchers' next step is to show that this phenomenon is also taking place in the wild. In addition, since the foraging gene is found in many animals, including honeybees, mice and humans, the researchers are examining how variations in the human foraging gene may be linked to food-...

Study offers clues to 'Broken Heart Syndrome'

...he coronary arteries on the tip of a catheter, may show whether the patient has clogged arteries or unstable plaques that are not visible on coronary angiography. These findings will help guide long-term treatment. "Because we don't yet know what causes this phenomenon, we don't know what the best lon...

The results show that tropical forests continue to accumulate carbon through to the end of the century, although they may become less efficient at higher temperatures. "The new body of information shows considerable value in preserving tropical forests such as tho...

Thymus transplants gives hope to babies with fatal immune disease

..., published Tuesday, May 15, in the journal Blood, show that 75 percent of the babies who received a thymus transplant were alive after one year. The recipient of the first transplant, in 1994, is alive and well. The current study was supported by the National Institutes of Health and the Food and Drug...

Scientists seek useful traits in wild cottons

..."We measure the leaf damage, identify cottons that show thrips resistance and subject those to further tests." Sheehan raises Lygus bugs, a secondary pest of cotton, and confines their feeding to certain parts of cotton plants using bug cages. The amount of damage they inflict on cotton fruit and...

Growing nerve cells in 3-D dramatically affects gene expression

...ibiotics ?may play out differently. Studies indeed show differences in behavior between cells cultured in 2-D and in 3-D. Cells cultured in 3-D, for example, grow faster.

Left-right wiring determined by neural communication in the embryonic worm

...eased in the May 18 issue of Cell, the researchers show that embryonic worms have a system of gap junctions -- "broadband" communication channels through which cells pass many kinds of molecules and electrical signals -- that allow growing neurons on the left and right to communicate with each other, a sy...
