Fig. 10. (A-D) The neural tube of a Tg(H2AF/Z)kca37;
Tg(H2AF/Z)kca66 embryo that had received an injection of
ASIP morpholinos. The arrows in A and B point to a metaphase plate that forms
parallel to the neuroepithelium, but shifts by 90° to divide
perpendicularly. Both daughter cells integrate into the same side of the
neural tube. (E-H) The neural tube of a hasm129
/hasm129; Tg(H2A.F/Z)kca37/+ embryo. As in
A-D, the metaphase plate forms parallel to the neurocoel, but shifts by
90° and the ensuing division is perpendicular. Arrows indicate the
dividing cell. Anterior is towards the top.
