British and Japanese Researchers Awarded The 2012 Nobel Prize For Stem Cell Research
2012-10-08 11:50:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Stem cell research has been a controversial, yet important advance in science and medicine for decades. Scientific research has been carried out in numerous areas pertaining to stem cells, and the work of two such researchers in the field have caught the eye of the most prestigious awards organization in the world. Britain´s Sir John Gurdon and Japan´s Shinya Yamanaka were both awarded the 2012 Nobel Prize for Medicine...

Epigenetics Of Adult Stem Cells Affect Organ Creation
2012-10-03 08:50:32

Alan McStravick for redOrbit.com - Your Universe Online Ask a handful of people about their thoughts and feelings on the use of stem cells for research and therapeutic means and you will find that they each have strong and varying positions on the topic. Outside the scientific community, however, little is known about this highly complex field of research. The politicization of stem cell research accompanied the 1998 discovery that embryonic stem cells, the building blocks of organ,...

Induced Pluripotent Stem Cells Similar To Cancer Cells
2012-09-30 06:38:13

April Flowers for redOrbit.com - Your Universe Online A research team from the University of California, Davis, has found evidence that a promising type of stem cell being considered for a variety of disease therapies is very similar to the type of cells that cause cancer. The cells, known as induced pluripotent stem cells (iPSCs) show promise as a source of replacement cells and tissues to treat injuries, diseases and chronic conditions. Although the iPSCs have the potential for such...

Tissue Regeneration Study Learns From Salamanders
2012-09-26 11:53:50

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the Salk Institute recently studied the regeneration of new limbs in salamanders and believe that the findings could be useful in studies on regenerative medicine for humans. The scientists published two different studies on the Mexican axolotl, a species of aquatic salamander that has lizard-like characteristics. They found that the salamanders needed more than just the activation of genes...

Stem Cell-based Regenerative Medicine Research May Be Helped Further With Discovery Of Reprogramming Signature
2012-09-19 08:55:31

Salk scientists show nine genes at heart of epigenetic changes in induced pluripotent stem cells Salk scientists have identified a unique molecular signature in induced pluripotent stem cells (iPSCs), "reprogrammed" cells that show great promise in regenerative medicine thanks to their ability to generate a range of body tissues. In this week's Proceedings of the National Academy of Sciences, the Salk scientists and their collaborators at University of California, San Diego, report that...

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). Knowing the architecture of this protein,  PRC2, for Polycomb Repressive Complex 2, should be a boon to its future use in the development of new and improved...

New Efficiency Brought To Stem Cell Reprogramming
2012-09-13 12:35:17

Biologists reveal genes key to development of pluripotency, in single cells Several years ago, biologists discovered that regular body cells can be reprogrammed into pluripotent stem cells – cells with the ability to become any other type of cell. Such cells hold great promise for treating many human diseases. These induced pluripotent stem cells (iPSCs) are usually created by genetically modifying cells to overexpress four genes that make them revert to an immature, embryonic...

In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The “molecular beacons,” which could advance tissue engineering research, light up when certain genes are expressed and don´t interfere with the development or operation of the stem cells. A novel set of custom-designed “molecular beacons” allows scientists to monitor gene...

Stowers scientists show how pluripotent stem cells mobilize in wounded planarian worms, to better understand stem cell behavior in regeneration and disease The skin, the blood, and the lining of the gut–adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
