Researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

Human embryonic stem cells purified in new
Posted by Milton 27 days ago (http://www.sciencedaily.com)
Researchers in Japan have unraveled the mystery of why human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells undergo programmed cell death (apoptosis) when cultured in isolation. By unlocking the potential of cell therapy techniques, the discovery promises new hope to sufferers of debilitating degenerative diseases.
Genetic differences that make some people susceptible to developing meningococcal meningitis and septicaemia, and others naturally immune, are revealed in a new study of over 6,000 people. The research is the largest ever genetic study of meningitis and septicaemia caused by meningococcal bacteria.

New 3-D imaging techniques for improved lung cancer drug development
Posted by Fabian 52 days ago (http://www.sciencedaily.com)
Advanced imaging technologies that promise to improve effective drug development to treat lung cancer are the focus of the current issue of Optics Express. Research outlines standardized approaches to measure and compare tumor size, as well as to validate the accuracy of such measurements. This validation is a critical new area of research as important new applications for these tools are being e
