Fig. 1. Ttk69 is expressed after Repo in lateral glia. (A-E) Ttk69 (red) and Repo (green) expression in lateral glia of early Stage 11 to Stage 14 embryos. Panels show either a merge of Ttk69 and Repo (co-expression is denoted by a yellow overlap) or Ttk69 expression alone. Later stages show separate confocal sections through either outer or inner layers of the CNS, allowing overlying glial populations to be distinguished. A schematic (Halter et al., 1995) of Repo-expressing glia at every embryonic stage is shown. Anterior is upwards; open arrow, midline; lgb, longitudinal glioblast; lg, longitudinal glia (colored purple in schematic); tp, tracheal pits; asterisk, glioblast 3-1 (Schmidt et al., 1997).
