Introducing stem cells
This presentation is intended as a flexible tool for scientists, science communicators and educators. Not all the slides will be useful for any one occasion. Choose the ones most suitable for your audience, mix them with your own slides, or just use the diagrams. Dear speaker… Presenter’s notes Each slide in the Basics and Cloning sections includes notes that give a simple, jargon- free explanation of the key points. The more detailed slides in the last section have much briefer notes and assume some knowledge of stem cell science. Further information and resources The 15-minute film, “A Stem Cell Story” provides an excellent introduction to stem cells and covers many of the concepts presented here.
