Scientists shed light on rise of blood cells
London - German scientists using new imaging technology said on Wednesday they have watched a single cell give rise to blood cells, bolstering understanding of stem cells. The findings could one day allow scientists to create blood in the laboratory that hospitals could give to patients needing transfusions, said Timm Schroeder of the Institute of Stem Cell research in Munich. "What we are looking at is where blood really comes from during development," he said in a telephone interview. "Blood cells are born during the embryo development and we wanted to know from what type of cells they came from." The researchers, who published their findings in the journal Nature, developed technology that allowed them to track hundreds of thousands of cells in real time over a week..... |

Stem cell 'cure' boy gets tumour
A boy treated with foetal stem cells for a rare genetic disease has developed benign tumours, raising questions about the therapy's safety. The boy, now 17, received the stem cells in 2001 at a Moscow hospital and four years later scans showed brain and spinal tumours, PLoS Medicine reports. Israeli doctors removed the abnormal growth from his spine and tests suggest it sprouted from the stem cells. Critics say the finding is evidence against the controversial therapy.. |

Research reveals some of Alzheimer's secrets
Scientists are unraveling some of the mechanisms behind the plaques in the brain that are a hallmark of Alzheimer's disease, offering new leads for drugs to treat the fatal brain-wasting disease. A team at Massachusetts General Hospital and Harvard Medical School in Boston reported on Thursday in the journal Science that amyloid plaques agitate a type of brain cell called an astrocyte needed for normal brain function.... |

Experts Fight Bird Flu Using Smallpox Vaccine
A team of scientists from the University of Hong Kong and the United States on Sunday said they have developed a new vaccine strategy against the H5N1 bird flu virus by genetically modifying a smallpox vaccine. The new vaccine is potentially a sound solution in case of an H5N1 bird flu pandemic, which many scientists have been worried about, said Malik Peiris, a microbiologist and bird flu research authority at the University of Hong Kong. Peiris said that the new vaccine has proven safer in experiments on mice and that "a single vaccine dose will provide rapid protective immune responses." It is also expected to enable fast mass production thanks to the possibility of using cell-culture methods, which could help avoid potential production bottlenecks as eggs will have to be used in the production of vaccines currently on offer..... |

Stanford researchers recruit twins for pain study
Twins Aurora Jumpe and Pandora Deam share a love of soccer, hiking, talking on the phone — and apparently a similar tolerance for "ouch." From broken ankles to dislocated shoulders, the sisters survived their childhood sports injuries with minimal tears. Now Jumpe and Deam are among the first twins to participate in a new study comparing pain sensitivity among identical and fraternal twins. Doctors from Stanford University School of Medicine and SRI International are recruiting twins to answer the question of nature versus nurture: Do genes affect how people experience pain and react to pain medications? "If you want to get at genes versus environment, you have to study humans who share the same environment," said Dr. Martin Angst, associate professor of anesthesia at Stanford University School of Medicine, who is leading the pain study. "Twin studies are a wonderful biologic setup.".... |

Canadians make stem-cell breakthrough
In 'great advance' to research, scientists discover new technique that safely turns skin cells into stem cells, removing risks and complications involved in using the technology March 2, 2009 at 8:00 AM EST TORONTO — Canadian researchers have discovered a new way to turn skin cells into stem cells with fewer potential risks to patients. Their work removes major barriers to using stem cells, which have an endless capacity for self-renewal, in new medical therapies for people with spinal cord injuries or diseases such as diabetes or Parkinson's. “We hope these stem cells will form the basis for treatment of many diseases and conditions that are currently considered incurable,” says Andras Nagy, of Toronto's Mount Sinai Hospital. He is the lead author of a groundbreaking paper published online Sunday by the journal Nature. Dr. Nagy and his colleagues are the first to reprogram human skin cells to an embryonic state without using a virus, collaborating on the new technique with Keisuke Kaji from the Medical Research Council Centre for Regenerative Medicine at the University of Edinburgh.... |

Researchers use single gene to return mature stem cells to embryonic state
Targeting the Good Cell A special report on the scientific race to turn cells into medicine. German scientists have sent mouse stem cells back to their embryonic origin by introducing just a single gene, a finding that could eventually lead to simpler, safer ways of generating cells for human medicine. A little more than a year ago, researchers in Madison and Japan proved that it is not only possible to turn a mature cell into something with the healing potential of an embryonic stem cell, but also far less difficult than most imagined. The new work, published today in the journal Cell, shows that it may be simpler still. The German team took neural stem cells from the brains of mice and used a virus to introduce a gene called Oct4. The gene is one of the four used by groups at the University of Wisconsin-Madison and Kyoto University in Japan when they reprogrammed human skin cells. The German experiment found that in mice, a single gene was all it took to transform the neural stem cells into the equivalent of embryonic stem ... |

Scientists a step closer to ‘reading minds’
A machine to read the mind came a step closer on Thursday, when scientists at University College London released the results of an experiment in which brain scans revealed the location of people moving around a virtual reality environment. Demis Hassabis, co-author of the study, said it was “a small step towards the idea of mind reading, because just by looking at neural activity we were able to say what someone was thinking”..... |
