Each year I metaphorically try to look into a crystal ball for stem cell predictions for the coming year and I did so for 2020, but the COVID-19 pandemic threw a monkey wrench into my predictions. It actually kind of blew some up. It also raised some interesting questions and dilemmas. For instance, do many …
