>“We found that GDF10 caused many different neurons in a dish to grow, including human neurons that were derived from stem cells,” said Dr. Carmichael. NGF (Nerve Growth Factor) is added to dishes nearly every time such experiments are done to get neurons to grow. I'm sure they plated them on laminin or whatever substrate works best for those neurons as well. I haven't read the paper, but from the layman's description this sounds like hype.
