(A) Microscopic pictograph showing the morphology of BMMSCs 24 h after induction. The cells started to stretch, became slender and protruded from the protuberant, and formed connections with neighboring cells. (B) IHC staining of neuron-specific protein NF-H of BMMSCs at 7 days after induction. The phenotypical features of neurons generated from the cells were distinguishable, including unipolar or bi/multipolar elongations, forming a neural network-like structure. (C) Control cells after 7 days without NF-H expression.
