<html><head></head><body><div>While stem cells and regenerative medicine are promising, it is important not to oversell them as a panacea. Translational science is a valley of death for promising ideas: remember when interferon was going to cure cancer? Growing new organs are not that easy, and if you need surgery to connect them to the body you are going to do risky cutting and anaesthesia. Killing cancer cells with bacteria and viruses requires you to master the immune system (guess why phage therapy is not widely used?) </div><div><br></div><div>Bodies are messy, complex environments that rarely are modular enough to allow magic bullets or neat replacement. Health is worth the effort, but the stretch between "awesome in the lab" to "in a clinic near you" is very long. Just saying. </div><br><br>Anders Sandberg,

We will have an all new heart that was created inside our own body, not grown in a lab. As for cancers, we will create bacteria and viruses in the lab that will go everywhere our blood goes and kill cancer cells. (That is, until we can redesign the immune system to do this automatically.) bill<br>
