Neuron induced differentiation of CAFSCs in vitro. A and B, morphology observation of induced cells under inverted microscope, dendron and axon emerge and grow mature after culture for 15 days; C, neuron specific marker NSE is detected positive by immunofluorescence histochemistry; D, neuron specific marker nestin is detected positive too. Red arrow stamp axon, dendron and teleneuron, respectively which are typical morphological markers of neuron.
