Patch-Clamp Recordings from Human Embryonic Stem Cells-Derived Fragile X Neurons.

Performing electrophysiological recordings from human neurons that have been differentiated in vitro, as compared to primary cultures, raises many challenges. However, patch-clamp recording from neurons derived from stem cells provides an abundance of valuable information, reliably and fast. Here, we describe a protocol that is used successfully in our lab for recording from both control and Fragile X neurons, derived in vitro from human embryonic stem cells.
