Wow, our 20th show already, we can’t believe it! In this episode we start by talking about the upcoming ISSCR meeting in Vancouver. The Stem Cell Podcast will be there at a booth doing live interviews, come on by. We then move into the science roundup and discuss a wide variety of topics such as using stem cells to model viral-host interaction, activating tooth stem cells with lasers, the loss of pain sensors leading to longer lives, more on the STAP story, green tea protecting you from cancer, and how a gene mutation in hair stem cells causes blonde hair. After that we bring on Dr. Dieter Egli from the New York Stem Cell Foundation (NYSCF) to talk about his work in using SCNT to derive new embryonic stem cell lines. We discuss his previous and current work, including his latest story just published in Nature last month. We close the show with a rant on an opinion piece where they proposed to eliminate graduate students by taking stipends away. Enjoy!
