A researcher's testimony on stem cell research

University of Michigan News Service: Sean Morrison, director of the U of M Center for Stem Cell Biology, testified before a US Senate Appropriations Subcommittee: "[W]e wish to use tissue-specific stem cells (often described as 'adult' stem cells in the newspaper) for the therapy, but we will obtain them from embryonic stem cells. This illustrates why it is scientifically meaningless to frame this debate as a choice between adult and embryonic stem cells. We sometimes need embryonic stem cells to generate adult cells for therapy."
