The engineers' dream of self-healing surfaces has taken another step towards becoming reality -- researchers have produced a electroplated layer that contains tiny nanometer-sized capsules. If the layer is damaged, the capsules release fluid and repair the scratch. http://www.physorg.com/news168525937.html Nanotechnology Mon, 03 Aug 2009 14:20:01 EST news168525937 Dental and tissue engineering researchers at Tufts University School of Dental Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have harnessed the pluripotency of human embryonic stem cells (hESC) to generate complex, multilayer tissues that mimic human skin and the oral mucosa (the moist tissue that lines the inside of the mouth). The proof-of-concept study is published online in advance of print in Tissue Engineering Part A. http://www.physorg.com/news167388870.html Medicine & Health Tue, 21 Jul 2009 09:55:05 EST news167388870 (PhysOrg.com) -- There is an increasing demand for skin. Manufacturers of pharmaceuticals, chemicals, cosmetics and medical engineering products need it in order to test the compatibility of their products with human skin. At the 2009 BIO International Convention in Atlanta from May 18 to 21, Fraunhofer researchers will be demonstrating how artificial skin can be manufactured in a fully automatic process. http://www.physorg.com/news161879775.html Medicine & Health Mon, 18 May 2009 15:37:40 EST news161879775 Cartilage, bones and the internal walls of blood vessels can be created by using common connective tissue cells from human skin. Researchers in reconstructive plastic surgery at Linköping University have successfully manipulated these tissue cells to take on different shapes depending on the medium they have been cultivated in. http://www.physorg.com/news160305560.html Medicine & Health Thu, 30 Apr 2009 10:19:37 EST news160305560 In a study featured on the cover of the May issue of The FASEB Journal, researchers describe how they are able to reprogram human adult skin cells into other cell types in order to decipher the elusive mechanisms underlying reprogramming. To demonstrate their point, they transformed human skin cells into mouse muscle cells and vice versa. This research shows that by understanding the regulation of cell specialization it may be possible to convert one cell type into another, eventually bypassing stem cells. http://www.physorg.com/news160305025.html Biology Thu, 30 Apr 2009 10:10:41 EST news160305025 Using a topical application of the antioxidant ellagic acid, researchers at Hallym University in the Republic of Korea markedly prevented collagen destruction and inflammatory response - major causes of wrinkles -- in both human skin cells and the sensitive skin of hairless mice following continuing exposure to UV-B, the sun's skin-damaging ultraviolet radioactive rays. http://www.physorg.com/news159546096.html Medicine & Health Tue, 21 Apr 2009 15:22:04 EST news159546096 They say dolphins are smart, and now people are borrowing a technology that was first used on the mammals. http://www.physorg.com/news157979058.html Medicine & Health Fri, 03 Apr 2009 12:05:02 EST news157979058 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://www.physorg.com/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://www.physorg.com/news150295895.html Biology Sun, 04 Jan 2009 12:51:35 EST news150295895 Scientists have new insight into the response of human skin to radiation and what drives the most aggressive and deadly form of skin cancer. The research, published by Cell Press in the November 21st issue of the journal Molecular Cell, may be useful in the design of new strategies for prevention of malignant melanoma. http://www.physorg.com/news146406507.html Biology Thu, 20 Nov 2008 12:28:27 EST news146406507
