WASHINGTON -- Scientists at a laboratory affiliated with the University of Wisconsin-Madison have developed a stem cell culture medium free of animal cells and used it to derive two new human embryonic stem cell lines.
The new work, reported in the journal Nature Biotechnology, is 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.
