Stem cells may become cancer vaccine Storrs, Conn. (UPI) Oct 8, 2009 
U.S. and Chinese scientists say they've discovered human stem cells hold the potential to vaccinate the body against colon cancer. The research, led by Associate Professor Zihai Li and Bei Liu, builds upon a century-old theory that immunizing with embryonic materials may generate an anti-tumor response. But the scientists say their finding advances the theory beyond animal resear ... read moreMoss may hold stem cell programming clues 
Tel Aviv, Israel (UPI) Sep 30, 2009 Israeli and German scientists say they've discovered moss might provide information allowing researchers to better program stem cells for medical purposes. Nir Ohad of Tel Aviv University and Professor Ralf Reski of the University of Freiburg said they discovered a new use for the polycomb group proteins found in moss. They said they determined the proteins play an important role in tel ... more

South Korean firm to open major dog cloning centre
Seoul (AFP) Aug 14, 2009A South Korean biotechnology firm will early next year open a centre capable eventually of producing up to 1,000 cloned dogs annually, a company executive said Friday. "We need this new facility to turn dog cloning services into a full-fledged business," Cho Seong-Ryul, director of RNL Bio, told AFP. The centre in Yongin city south of Seoul will cost some five million dollars and focus ... more In world first, Chinese researchers create pig stem cells 
Paris (AFP) June 3, 2009Chinese researchers said on Wednesday they had created versatile stem cells from pigs, a ground-breaking achievement that could open up new paths for combatting human disease. Doctors led by Lei Xiao, of the Shanghai Institute of Biochemistry and Cell Biology, took adult cells taken from a pig's ear and bone marrow and reprogrammed them so that they became so-called pluripotent stem cells. ... more Adult stem cells revert to embryonic state
San Francisco, April 13, 2009 U.S. scientists say they have, for the first time, returned adult mouse cells to their embryonic pluripotent state, meaning they can become any cell type. The University of California-San Francisco researchers said they used tiny molecules called microRNAs to reprogram the cells. The achievement suggests scientists will soon be able to replace retroviruses and even genes currentl ... more Scientists seek extra embryos 
Nashville, April 5, 2009 Demand has risen for couples to donate excess embryos to science since the U.S. government lifted restrictions on embryonic stem cell research, researchers say. The (Nashville) Tennessean reported Sunday that about 500,000 embryos are stored in U.S. fertility clinics, some of which will be transferred back to the mother. However, others will be discarded. Researchers say they can ... more |

Japanese cure spinal damage in mice
Tokyo (UPI) Feb 4, 2009 Japanese scientists said Wednesday they cured mice whose hind legs were paralyzed by damage to their spinal cords, offering hope to people with paralysis. Researchers at Keio University in Tokyo announced at a symposium that they had achieved the first confirmed case in which movement in paralyzed mice's limbs was restored by transplanting neural stem cells grown from human iPS cells ... more 'Scrawny' gene keeps stem cells healthy 
Baltimore (UPI) Jan 7, 2009The discovery of a "scrawny" gene in fruit flies may improve researchers' ability to direct stem cell differentiation in desired ways, U.S. researchers say. The gene -- called scrawny because of the appearance of mutant adult flies -- appears to be a key factor in keeping a variety of stem cells in their undifferentiated state, the researchers at the Carnegie Institution's Department of ... more Stem cells used in trachea transplant
Barcelona, Spain (UPI) Nov 19, 2008 The first successful human windpipe transplant using the patient's stem cells was completed in Spain, physicians at four European universities announced. One physician said the procedure's success indicated "we are on the verge of a new age in surgical care," The New York Times reported on its Web site Wednesday. Physicians at universities in Spain, England and Italy helped in ... more Japanese scientists clone embryo of endangered rabbit 
Tokyo (AFP) Nov 18, 2008Japanese scientists said Tuesday they had created a cloned embryo from the dead body of an endangered species of rabbit and are hoping for a birth. The Amami rabbit, or Pentalagus furnessi, lives on only two small islands in southwestern Japan. It is designated as endangered species by Japan's environment ministry, with an estimated population of less than 5,000. Professor Yoshihiko ... more |
