By Patricia Reaney LONDON -- A gene named after the mythical Celtic land of the ever young could help explain how to reprogram adult cells into embryonic stem cells to treat diseases, researchers said on Wednesday. They discovered that the gene called Nanog helped to transform adult mouse cells into embryonic stem cells after cell fusion -- when two cells are combined to form a hybrid. "The effect of Nanog is remarkable. All the hybrid cells became fully converted to embryonic stem cells,"...

What exactly makes a stem cell a stem cell? The question may seem simplistic, but while we know a great deal of what stem cells can do, we don't yet understand the molecular processes that afford them such unique attributes. Now, researchers at Whitehead Institute for Biomedical Research working with human embryonic stem cells have uncovered the process responsible for the single-most tantalizing characteristic of these cells: their ability to become just about any type of cell in the body,...

PITTSBURGH -  Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express. A part of the placenta called the amnion, or the outer membrane of the amniotic sac,...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Scientists looking for easier and less-controversial alternatives to stem cells from human embryos said on Friday they found a potential source in placentas saved during childbirth. They described primitive cells found in a part of the placenta called the amnion, which they coaxed into forming a variety of cell types and which look very similar to sought-after embryonic stem cells. With 4 million children born in the...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
