• Advanced Cell Technology to obtain patent for cellular reprogramming, generation of iPS cells

  August 18, 2010

  [Story ID: 3431] Advanced Cell Technology, Inc. announced today that it is positioned to obtain significant patents relating to cellular reprogramming and the generation of induced pluripotent stem (iPS) cells. iPS cells are similar to embryonic stem (ES) cells, except they are generated from adult cells such as skin using certain reprogramming factors, without the [...]

• ACT Poised to Obtain and Control Key Patents to Generating iPS Cells

  August 17, 2010

  [Story ID: 3421] MARLBOROUGH, Mass.—-Advanced Cell Technology, Inc. announced today that it is positioned to obtain significant patents relating to cellular reprogramming and the generation of induced pluripotent stem cells. iPS cells are similar to embryonic stem cells, except they are generated from adult cells such as skin using certain reprogramming factors, without the controversial [...]

• Scientists develop new method for anticancer drug delivery

  July 28, 2010

  [Story ID: 3312] Combining nature and Greek mythology, researchers at the Technion-Israel Institute of Technology have developed a tiny “Trojan Horse” system for delivering cancer-fighting drugs. With this system, the drugs are delivered only once they are inside the cancerous cells, so there is no damage to the healthy cells in the surrounding area.

• Scientists reprogram adipose tissue derived cells to iPS cells

  July 27, 2010

  [Story ID: 3265] Australian scientists from the Monash Institute of Medical Research have “reprogrammed” adult mouse fat cells and neural cells to become stem cells that can differentiate into a variety of different cells (pluripotency). The cells, called “induced pluripotent stem cells” are nearly identical to the naturally occurring pluripotent stems cells, such as embryonic [...]

• Study shows reprogramming of Legionella for its own survival

  July 26, 2010

  [Story ID: 3214] When it infects the lungs, the Legionnaire’s bacterium Legionella pneumophila causes acute pneumonia. The pathogen’s modus operandi is particularly ingenious: it infiltrates deliberately into cells of the human immune system and injects a host of proteins which then interfere in the normal cellular processes. Scientists from the Max Planck Institute of Molecular [...]

• Mental exercises may help reverse age-related cognitive decline

  July 21, 2010

  [Story ID: 3084] Specialized brain training targeted at the regions of a rat’s brain that process sound reversed many aspects of normal, age-related cognitive decline and improved the health of the brain cells, according to a new study from researchers at University of California, San Francisco.

• Clues behind macrophages from being good cops to bad cops identified

  July 16, 2010

  [Story ID: 2930] Immune system cells called macrophages spring into action to surround and destroy threats such as viruses or cancer cells. But sometimes the would-be protective response leads to persistent inflammation, which, in turn, can cause disease.Scientists don’t know exactly how macrophages cross the line from being good cops to bad cops, but researchers [...]

• Study shows disruption of two genes that control circadian rhythms can lead to diabetes

  July 14, 2010

  [Story ID: 2843] Disruption of two genes that control circadian rhythms can lead to diabetes, a researcher at UT Southwestern Medical Center has found in an animal study. Mice with defective copies of the genes, called CLOCK and BMAL1, develop abnormalities in pancreatic cells that eventually render the cells unable to release sufficient amounts of [...]

• Scientists demonstrate how neural stem cells, precursor cells control growth of glioblastomas

  July 7, 2010

  [Story ID: 2697] In their latest research, scientists of the Max Delbr-ck Center for Molecular Medicine Berlin-Buch, Germany, have demonstrated how the brain’s own stem cells and precursor cells control the growth of glioblastomas. Of all brain tumors, glioblastomas are among the most common and most aggressive.

• Transplanted beta cells protect themselves by adapting to their new homes

  July 3, 2010

  [Story ID: 2634] For transplanted beta cells, life is tough. Not only are the insulin-producing cells in a stranger’s body, tucked into the liver rather than the pancreas, they are a bit short on oxygen and blood, and they are often exposed to raised levels of glucose.
