A blockbuster study in which US researchers reported that they had turned human skin cells into embryonic stem cells contained errors, its lead author has acknowledged. http://phys.org/news288548751.html Biology Thu, 23 May 2013 17:26:02 EST news288548751 In a paper published in Cell yesterday, scientists from the US and Thailand have, for the first time, successfully produced embryonic stem cells from human skin cells. http://phys.org/news288260300.html Biology Mon, 20 May 2013 09:18:34 EST news288260300 Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons. http://phys.org/news247145057.html Biology Mon, 30 Jan 2012 15:00:01 EST news247145057 Human skin cells can be converted directly into functional neurons in a period of four to five weeks with the addition of just four proteins, according to a study by researchers at the Stanford University School of Medicine. The finding is significant because it bypasses the need to first create induced pluripotent stem cells, and may make it much easier to generate patient- or disease-specific neurons for study in a laboratory dish. http://phys.org/news225635887.html Biology Thu, 26 May 2011 13:39:14 EST news225635887 (PhysOrg.com) -- In an important breakthrough, scientists at McMaster University have discovered how to make human blood from adult human skin. http://phys.org/news208358434.html Biology Sun, 07 Nov 2010 13:34:36 EST news208358434 Scientists have determined that chronic wounds might have trouble healing because of the actions of a tiny piece of a molecular structure in cells known as RNA. http://phys.org/news188497286.html Medicine & Health Mon, 22 Mar 2010 17:21:41 EST news188497286 The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell, a Cell Press publication, shows for the first time that neural stem cells taken from adult mice can take on the characteristics of embryonic stem cells with the addition of a single transcription factor. Transcription factors are genes that control the activity of other genes. http://phys.org/news153059473.html Biology Thu, 05 Feb 2009 12:31:44 EST news153059473 Just after 5 p.m. doors rattle shut and feet begin to shuffle past the narrow lab where Karim Si-Tayeb sits hunched over a microscope, all but invisible to the scientists leaving the Medical College of Wisconsin. Si-Tayeb has already worked eight hours and will work five more, eyes locked on the living cells in his care. Under the microscope, their tiny colonies resemble constellations of tightly packed stars. They carry his ambition. http://phys.org/news150295895.html Biology Sun, 04 Jan 2009 12:51:35 EST news150295895
