The Interactive Fly
Lateral views of Drosophila CNS [image © 1998 Ward Odenwald]
Lateral views of Drosophila CNS stained for Hunchback, Pdm-1 and Castor. Two serial confocal immunofluorescent views of embryos triple-labeled for Hb (green), Pdm-1, and (green) Cas (red). Hb is expressed in early sublineages, Cas is expressed in late sublineages and Pdm-1 is expressed in intermediate sublineages. Note the more ventral-ventral/lateral position of the Cas-positive cells relative to the more internal Pdm-1 and dorsally positioned Hb sublineages. Staining of the intestinal yolk cells (green) is non-specific. Hb is also expressed in a subset of cells lining the gut.
