I have the opportunity to travel to the United States in early March. As I’ll be in New York City for some days I’d like to visit several good stem cell labs, but I do not know where these labs are in the Big Apple and whom to contact? Unfortunately a short Google period did not help me a lot in this respect, I don’t know why. Would you be kind enough to help me and offer some? Human filters are the best, when you need strongly selected contextual information.
