Figure S1. Examples of interphase and early prophase cells. a, b Interphase cells showing round nuclei encased by a continuous double nuclear membrane (DNM). c A possible early prophase cell characterized by an undulated nuclear membrane. The asterisk indicates the cell region shown at higher magnification. Scale bars: a (left image), b and c, 5 μm; a (right image), 1 μm. (TIF 17489 kb)
