HTTP:: Embryonic Stem Cell Genetic Control Circuit Found
--------
Spanish experts from the Universitat Politecnica de Catalunya (UPC), working together with colleagues from the University of Cambridge (UC), have managed to discover the genetic circuit that in essence controls the behavior of stem cells and determines traits such as differentiation and pluripotency. UPC School of Industrial and Aeronautical Engineering of Terrassa (ETSEIAT) Department of Physics and Nuclear Engineering Lecturer Jordi Garcia Ojalvo has been the one who has discovered the mechanism. The new finds cast some doubts over established knowledge, which has it that stem cells are in their natural state inert, in that they require an external stimulus in order to start differentiating into the various types of cells that make up the human body. This ability to turn themselves into any other type of cells is called pluripotency, and is the trait that geneticists rely on to eventually develop a technology that would enable health care providers to grow artificial or!
gans that would replace damaged ones. Working together with Alfonso MartÃnez Arias's research group at the UC, Garcia-Ojalvo determined that the stem cells were not naturally in a neutral, static state, but that they changed constantly. Additionally, the two discovered that a subset of stem cells existed that ensured a level ...
