Neuron-Specific Fluorescence Reporter-Based Live Cell Tracing for Transdifferentiation of Mesenchymal Stem Cells into Neurons by Chemical Compound

Figure 5

Time-lapse live cell images of (a) the DMSO-treated group and (b) the NHPDQC-treated group in pTα1-DsRed2-transfected MSCs. NHPDQC treatment to induce neuronal differentiation showed that the fluorescence signals in MSCs transfected with pTα1-DsRed2 were gradually increased according to cellular phenotypic changes. (c) Neurite growth (gray) and fluorescence signals (black) were increased in the NHPDQC-treated group than the DMSO-treated cell group from 2 h after treatment. Fluorescence signal in the NHPDQC-treated group was dropped at 24 h after treatment. In contrast, neurite growth was progressed at 30 h after treatment.
