Scientists Report a Crucial Gain in Growing Stem Cells

January 3, 2006 | Source: New York Times

Scientists at a laboratory affiliated with the University of Wisconsin have developed a stem-cell culture medium free of animal cells and used it to derive two new human embryonic stem-cell lines.

The work is considered a crucial step in stem-cell research because it will allow growth of these cells without using animal products that can harbor viruses and other potential sources of problems.
