They say the antibody blocks a protein known as CD47, that sends "don't eat me" signals that cancer cells use to stop macrophages and other cells of the immune system from gobbling them up. Anti-CD47 is the first antibody treatment to work against a variety of human solid tumors. The investigators said they are now eager to get started with phase 1 and phase 2 clinical trials in humans within the next two years. The treatment also significantly reduced the ability of the tumors to spread (metastasize) to other parts of the mice's bodies, and in some cases, the animals appeared to be "cured".

ScienceDaily (Mar. 26, 2012) A breakthrough using cutting-edge stem cell research could speed up the discovery of new treatments for motor neuron disease (MND). The international research team has created motor neurons using skin cells from a patient with an inherited form of MND. Role of protein Using patient stem cells to model MND in a dish offers untold possibilities for how we study the cause of this terrible disease as well as accelerating drug discovery by providing a cost-effective way to test many thousands of potential treatments said Professor Siddharthan Chandran, Director of the University's Euan MacDonald Centre for MND Research. The study discovered that abnormalities of a protein called TDP-43, implicated in more than 90 per cent of cases of MND, resulted in the death of motor neuron cells. This is the first time that scientists have been able to see the direct effect of abnormal TDP-43 on human motor neurons. The study, led by the University of Edinburgh's Euan MacDonald Centre for Motor Neuron Disease Research, was carried out in partnership with King's College London, Columbia University, New York and the University of San Francisco. Motor neuron disease MND is a devastating, untreatable and ultimately fatal condition … Continue reading →

By Carolyn Y. Johnson, Globe Staff An international stem cell conference scheduled to take place next month at the Vatican has been cancelled, and the Catholic News Agency has reported that the choice of speakers, which included a prominent Boston embryonic stem cell researcher, was a factor. Dr. George Q. Daley, a stem cell researcher at Childrens Hospital Boston, was scheduled to give the opening lecture at the Third International Congress on Responsible Stem Cell Research. Daley said in an interview that he received a brief e-mail late last week announcing that the conference had been cancelled and that an explanation would follow shortly. Unnamed sources told the Catholic News Agency that the event, as planned, would have presented an unacceptably ambivalent stance on embryonic stem cell research. The Catholic Church opposes human embyronic stem cell research because it requires the destruction of embryos. One unnamed member of the Pontifical Academy for Life told the news agency: The news of the cancellation of the Congress is an enormous relief to many members of the Pontifical Academy for Life, who felt that the presence on its program of so many speakers, including the keynote speaker, committed to embryonic stem cell research, … Continue reading →

Nature | Health A Monsignor and Officer for Studies at the Pontifical Academy for Life called the cancellation a "sad event." Attendees are set to receive an official explanation March 26, 2012 By Ewen Callaway of Nature magazine The Vatican has abruptly cancelled a controversial stem-cell conference that was set to be attended by the Pope next month. The Third International Congress on Responsible Stem Cell Research, scheduled for 25-28 April, was to focus on clinical applications of adult and reprogrammed stem cells. But a number of the invited speakers, including Alan Trounson, president of the California Institute for Regenerative Medicine in San Francisco, and keynote speaker George Daley, a stem-cell scientist at Children's Hospital Boston in Massachusetts, are involved in research using human embryonic stem cells, which the Catholic Church considers unethical. The previous two congresses had also included scientists who worked on such cells, without generating much controversy. Father Scott Borgman, secretary of the Church's Pontifical Academy for Life, one of the conference organizers, says that logistical, organizational and financial factors forced the cancellation, which was announced on 23 March. The academy weighs in on bioethical and theological issues that are relevant to Church teachings. The Catholic News … Continue reading →

The departure of three University of Nebraska regents this year and the re-election campaign of a fourth is reviving debate over a controversial issue some believe should be laid to rest. Two of the three departing regents, Chuck Hassebrook of Lyons and Jim McClurg of Lincoln, opposed a proposal considered by the Board of Regents in November 2009 that would have limited embryonic stem cell research at the University of Nebraska Medical Center to only cell lines approved under former President George W. Bush. Expansion had become a possibility since President Barack Obama relaxed the Bush guidelines. Hassebrook and McClurg joined two other regents in killing the proposal by voting against the four who supported it. Pro-life activists believe embryonic stem cell research is morally wrong because harvesting the stem cells requires destroying an embryo. Regent Randy Ferlic of Omaha, who supported the proposal to limit the research, also will leave the Board of Regents after this year. Bob Whitehouse of Papillion, who opposed the measure, is seeking re-election. Ten candidates are seeking the three retiring regents' seats, and candidate, Larry Bradley, is challenging Whitehouse. Pro-life advocates said they see opportunity in the departure of two of the regents who … Continue reading →

Scientists in SA have generated non-embryonic stem cells for the first time, the Council for Scientific and Industrial Research (CSIR) announced on Tuesday. These "induced adult pluripotent stem cells" were developed from adult skin cells and can be prompted to grow into any type of adult cell, such as those in the heart or brain. The technology is important for research into regenerative medicine, but is not yet widely used. While the technology is not novel, the development of the capacity to grow these stem cells in SA is important for researchers investigating diseases affecting Africans, said CSIR post-doctoral fellow Janine Scholefield. The CSIR had replicated techniques devised by Japanese researchers in 2007. "Cutting-edge medical research is not useful to Africans if knowledge is being created and applied only in the developed world," said CSIR head of gene expression and biophysics Musa Mhlanga. "Given the high disease burden in Africa, our aim is to become creators of knowledge, as well as innovators and expert practitioners of the newest and best technologies," The CSIR said that adult-generated stem cells were more acceptable to people who objected to using stem cells from embryos. "The other critical thing is the cells (that will … Continue reading →

SACRAMENTO (KABC) -- Eight years ago voters agreed to fund California's stem cell agency, hoping it would yield new treatments for various conditions. Now the agency is running out of funds and any practical cures are still years away. The California Institute for Regenerative Medicine (CIRM) is about to enter a crucial stage in stem cell research: going to clinical trials. The most promising experiments could cure diabetes, HIV, sickle-cell anemia and blindness in the elderly. "You don't really get to find out whether the potential of the treatment is really going to be effective until you start to treat the patients," said Alan Trounson, president of the California Institute for Regenerative Medicine. CIRM's board is discussing how much to allocate for that trial phase. Through voter-approved bonds under Proposition 71 (The California Stem Cell Research and Cures Act), it has already given out or spent half of the $3 billion, but despite the medical promise, there's little to show for it beyond basic research and several high-tech laboratories. But the agency says the breakthroughs will come over the next few years, way ahead of the rest of the world. "This would all be happening in California, all driven by … Continue reading →
