On Monday 12 September, we livestreamed a session from our meeting ‘From Stem Cells to Human Development’, as part of our Development presents… webinar series. We concluded the session with a panel discussion on technical, ethical and legal challenges of studying early human development. The panel included Amander Clark, Robin Lovell-Badge, Sergiu Pasca, Sarah Teichmann and Magdalena Zernicka-Goetz and the discussion was chaired by Patrick Tam.
