Foxd3 joins the small, but growing list of stem cell regulating genes
In the search to understand the nature of stem cells, researchers at the University of Pennsylvania School of Medicine have identified a regulatory gene that is crucial in maintaining a stem cells ability to self-renew. According to their findings, the Foxd3 gene is a required factor for pluripotency – the ability of stem cells to turn into different types of tissue – in the mammalian embryo. Their research is presented in the October 15th issue of the journal Genes and Development.
"Stem cells represent a unique tissue type with great potential for disease therapy, but if we are to use stem cells then we ought to know the basis of their abilities," said Patricia Labosky, PhD, an Assistant Professor in the Department of Cell and Developmental Biology. "Among the stem cell regulatory genes, it appears that Foxd3 gene expression keeps stem cells from quickly differentiating – that is, developing into different types of tissue – holding back the process so that an embryo will have enough stem cells to continue developing normally."

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
