During the past, scientists grew stem cells on areas that contained mouse cells. That left scientists with nagging questions about feasible contamination of stem cells with disease-causing animal infections – a stumbling block for using stem cells in potential medical applications. And that growth program was what scientists term ‘undefined.’ There were variations from batch to batch of mouse cells, and researchers never really knew what the stem cells had been coming into contact with and how it might be changing them. The synthetic, chemically-defined, areas finished that uncertainty. The approach was inexpensive, basic and a much-needed advance in creating stem cells, Kiessling described.
