Fig. 1. Numb and transitin colocalize in developing chick neural tissues.
Blue is DAPI nuclear staining. (A) Transverse section of an embryonic
day (E)5 optic tectum, stained with anti-Numb (green) or 7B3 anti-transitin
(purple). Arrowheads indicate radial fibers of neuroepithelial cells.
(B) Transverse section of an E4 spinal cord. Three mitotic figures are
indicated by arrowheads. Numb (green) and transitin (purple) colocalize in the
basal side of mitotic cells. (C) Transverse section of E4 dorsal root
ganglia. A mitotic cell in anaphase is indicated by an arrowhead. Numb and
transitin colocalize in a part of the cell cortex.
