Figure 11: MAP2 expression in a heterokaryon. (a) Neuronal nucleus (larger and darker) and an adjacent reprogramming oligodendrocytic nucleus (smaller in size and brighter). (b) The same section area under a green filter. The circle of green matter (MAP2 immunoreactivity) surrounds the nuclei of both the neuron and the oligodendrocyte. (a) DAPI staining. (b) Immunocytochemical detection of MAP2 labeled by DyLight 488. The scale bar is 10 μm.
