When boundaries benefit science and society

In the rapidly moving field of stem cell and embryo research, research questions often sit at the intersection of scientific inquiry and ethical considerations. The International Society for Stem Cell Research (ISSCR) produces guidelines to help navigate decisions in this area. For Cell’s 50th Anniversary Focus on Developmental Biology, scientific editor Sarah Geisler discussed the importance of the ISSCR guidelines on stem cell and embryo research for both the stem cell community and the broader public with Amander Clark, Robin Lovell-Badge, and Janet Rossant, who have been involved in the ongoing evolution of the guidelines. A lightly edited transcript of their conversation is shared here.
