Oosight microscope enables embryonic stem cell breakthrough

A noninvasive, polarized light microscope invented at the Marine Biological Laboratory played a crucial role in the successful derivation of stem cells from cloned monkey embryos as reported in the Nov. 22 issue of Nature. Shoukhrat Mitalipov of Oregon Health & Science University and collaborators succeeded largely due to the Oosight microscope system developed by CRi Inc., based on technology invented by Rudolf Oldenbourg and others at the MBL in Woods Hole, Mass.

2. A matter of force
   05-03-2007 · EurekAlert!
   When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells. Researchers from the European Molecular Biology Laboratory have now worked out the mechanism underlying asymmetric cell division in nematode worms.

   For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries. His most recent discovery, which produces billions of neural cells from a few stem cells, could now aid in national security. In collaboration with the US Naval Research Laboratory, Stice hopes to use his recently developed neural cell kits to detect chemical threats.

7. Widespread support for nonembryonic stem cell research, VCU Life Sciences Survey shows
   12-19-2007 · EurekAlert!
   The VCU Life Sciences Survey is the first poll to reflect the discovery reported internationally in November that human skin cells can be used to create stem cells or their near equivalents. When asked about the implications of this development, more than six in 10, or 63 percent, say that both embryonic and nonembryonic stem cell research is still needed, 22 percent say this development means embryonic stem cell research is no longer necessary.

   A team from the Medical College of Wisconsin in Milwaukee has applied for a patent on their work to isolate, grow and identify a new and readily-available type of adult stem cell that is found in the bulge of hair follicles, and appears to have a potential for diversification similar to that of embryonic stem cells.

9. Simple recipe turns human skin cells into embryonic stem cell-like cells
   11-20-2007 · EurekAlert!
   A simple recipe -- including just four ingredients -- can transform adult human skin cells into cells that resemble embryonic stem cells, researchers report in an immediate early publication of the journal Cell, a publication of Cell Press. The converted cells have many of the physical, growth and genetic features typically found in embryonic stem cells and can differentiate to produce other tissue types, including neurons and heart tissue, according to the researchers.
