Figure 4From: Delta-Notch signaling and lateral inhibition in zebrafish spinal cord developmentNeural precursor cells prematurely exit the cell cycle and develop as neurons in dlAdx2mutant embryos. Labeling to detect proliferative cells by BrdU incorporation (brown) and post-mitotic neurons by huC expression (blue) on transverse sections through trunk neural tube. Both proliferative cells and post-mitotic neurons are evident in a wild-type embryo (A) whereas a mutant embryo had many more neurons and fewer proliferative cells (B). Scale bar, 10 μm.Back to article page
