Neurogenesis during early and mid-embryogenesis: BrdU labeling in whole mount embryos. (A, B) In earlier stages (about E38%), BrdU+ cells are homogeneously distributed throughout the germ band with pronounced accumulations in the appendage anlagen. The paired deutocerebral regions show an aggregation of labeled cells (dotted line). (C, D) During mid-embryogenesis (E50%), the embryos are characterized by a persistently high rate of mitotic activity. The deutocerebrum (DC, dotted line in (D)) stands out from the protocerebrum and contains large spherical BrdU+ cells. (E-G) Higher magnification of brain neuroblasts (NBs) and associated progeny, the ganglion mother cells (GMCs). Neuroblasts can be found in early prophase (F) or in early telophase (G). Abbreviations: A1, anlage of antenna 1; A2, anlage of antenna 2; OA, optic anlagen; PC, protocerebrum. Scale bars: 50 μm (A-D), 10 μm (E-G).
