Figure 3. The role of zccndx in cell proliferation and regulation of the numbers of motor neuron progenitors (pMNs).(A) Confocal images showing lateral views of the heads of control-MO-injected (panel a) or ccndx-MO-injected (panel b) embryos stained with anti-pH3 (red in panels a and b) or anti-BrdU (green in d and e). Panels c and f: graphs showing the number of proliferating cells (pH3 or BrdU positive) at 24 hpf. The asterisks indicate significant differences between the control and experimental morphants. The n value is indicated. (B) Whole–mount in situ hybridization of motor neurons and interneuron markers in control-MO and zccndx ATG-MO-injected embryos. Probes against olig2 (a and b), nkx6.1(c and d), isl1 (e and f), and vsx1 (g and h) were used for detection. control MO-injected embryos are shown in panels a, c, e and g while ccndx ATG-MO-injected embryos are shown in panels b, d, f and h. Motor neurons (MN) were lost (panels b, f, lost MNs indicated by arrowheads), while interneurons (IN) (panels d and h) were unaffected. Scale bar, 100 mm.
