Fig. 5. Late telophase nuclear morphology. (c) FESEM of almost separated ‘daughter’ nuclei, (d) also shown in thin section. (a,b) Spindle membrane (stars) has fused with NE and appears to be flattening into it. NPCs form at the junction between the spindle envelope and NE (arrows), and we also observe a novel ‘rosette’ structure (circled). (e-m) Montage of selected intermediates at this stage. (e-g) Stabilized pores with structures, probably the beginnings of the spoke ring complex, assembled into central channel. (h) Rosette structure. (i-m) Star rings.
