Figure 9: Electron microscope image of heterokaryons. (a) The oligodendrocyte’s nucleus (right) and the neuron’s nucleus (left) are located in the fused cytoplasm of the two cells. The cell membrane, which previously divided the cells, is observed as a fragment (arrows). The chromatin in the oligodendrocyte’s nucleus has divided into heterochromatin (dark accumulations at the nuclear membrane and in the center of the nucleus) and euchromatin (granulated matter at the larger part of the nuclear area). Euchromatin in olygodendrocyte’s nucleus darker than euchromatin in neuron’s nucleus. (b) The oligodendrocyte’s nucleus (right) and the neuron’s nucleus (left). Euchromatin in the oligodendrocyte’s nucleus has the same light staining as that in the neuron’s nucleus. The scale bar is 2 μm.
