Live Chat: The Science and Ethics of Stem Cells From Human Cloning

See below for the chat box. Join us each Thursday at 3 p.m. EDT for a live conversation with leading scientists and expert reporters.
Today's Topic

After a decade of failed attempts, researchers have finally managed to establish stem cell lines derived from cloned human embryos. Such patient-specific stem cells are potentially valuable for studying—and perhaps someday treating—a variety of diseases. What does the cloning breakthrough mean for medical research? And what ethical concerns does it raise? Does it pave the way for reproductive human cloning? Should the United States join other countries in banning any attempts to use the technique to make a human baby? And should donors of human oocytes—necessary for the cloning procedure—be paid for their donations, or does that open the door to exploitation? Does an alternative way of making patient-specific stem cells, called iPS cells, make clone-derived stem cells superfluous?

Join stem cell and cloning expert Dieter Egli of the New York Stem Cell Foundation and bioethicist Debra Mathews of Johns Hopkins University on Thursday, 27 June, at 3 p.m. EDT on this page for a live chat when we address these questions and take yours. Be sure to leave your queries for our guests in the comment box below.
