Cell morphology under phase contrast microscopy. (A) Co-culture group, neuron cell bodies were translucent with a slender shape and multiple processes, typical of neurons. (B) neural stem cells group, a smaller amount of neuron cells were present, and the state of neurons was not as healthy as the co-culture group. (C) In the Schwann cell group, cell morphology was the same as culturing in Schwann cell culture medium and had no differentiation trend. Scale bar, 100 µm.
