Fig. 6. Centrosome duplication is not affected in fue mutants. Centrosomes
at the eight-cell stage during interphase, visualised with an antibody
directed against
-tubulin (green) and nuclei labelled with DAPI (blue)
from (A) a wild-type embryo, (B) fue embryo, (C) an embryo treated
with the DNA replication inhibitor aphidicolin. (D-F) Enlargements of single
centrosome pairs of A-C, respectively. Centrosomes are present and are able to
duplicate in all fue cells as well as the (anucleate) cells of
aphidicolin-treated embryos, demonstrating that the centrosomes can duplicate
independently from nuclei. Scale bars: 20 µm.
