Article Title: Nanotopography-mediated Reverse Uptake for siRNA Delivery into Neural Stem Cells to Enhance Neuronal Differentiation
doi: 10.1038/srep01553
Figure Lengend Snippet: (a) RT-PCR analysis reveals differences in transcript levels for SOX9 and differentiation markers for neurons (TuJ1), astrocytes (GFAP) and oligodendrocytes (MBP) in the presence or absence of si SOX9 and/or NanoRU. (b) Quantitative comparison of the percentage of cells expressing TuJ1 and GFAP. Student's unpaired t-test was used for evaluating the statistical significance for cells stained for TuJ1, compared to the si SOX9 on NanoRU condition (** = P < 0.001). (c) Fluorescence images of cells stained for the nucleus (blue), the neuronal marker TuJ1 (red, left column), the astrocyte marker GFAP (green, middle column) and merged (last column) show the extent of differentiation of NSCs grown on: no NanoRU nor si SOX9 coating (top row), NanoRU without si SOX9 coating (middle row), and NanoRU with si SOX9 coating (bottom row). Scale bars: 50 μm.
Article Snippet: To study the extent of neuronal differentiation the primary mouse antibody against TuJ1 (1:500, Covance) and primary rabbit antibody against MAP2 (1:100, Cell Signaling) was used and for glial differentiation the primary rabbit antibody against GFAP (1:300, Dako) was used.
