Fig. 4. Cell types in the EM lineage are not altered in ems mutant clones. (A-L) Single optical sections. Co-labelling of GFP-marked wild-type and ems mutant MARCM clones (green; for genotypes see Materials and methods) with antibodies against protein indicated on each panel (magenta). The anti-Ems immunoreactivity used for the identification of EM lineages is omitted for clarity. Neuroblasts encircled with dots; GMCs marked by arrowheads. Scale bar: 5 µm.
