Researchers at Ohio State University have developed a method for mass-producing embryonic stem cells.That’s important because traditional laboratory methods used to grow these cells are costly and don’t produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University. Federal rules forbid the federal funding of research on human embryonic stem cell lines that aren’t listed on the National Institutes of Health’s Human Embryonic Stem Cell Registry. There are currently 22 embryonic stem cell lines on the registry, and the demand for these cells is steadily growing.
