Figure 2. Transcription Factor Expression in Post-Embryonic VNC Lineages.

Figure 2.

(A) Immature adult thoracic VNC neuropils depicted in the late third instar larval CNS. Frontal (left) and lateral (right) views.

(B) Lateral view (left) of the third instar larval CNS depicting cell bodies in the cortex expressing Chinmo (red) and Broad-Complex (Br-C)(blue) TFs. NB lineage (right) comprising of embryonic and post-embryonic progeny; depicting proportions of Chinmo and Broad-Complex (Br-C) TF expression and corresponding to a ~2-fold decrease in cell size (48).

(C) Unique combinations of TF expression identify post-embryonic hemilineages of NB2–3 (Lin15A-B), NB6–1(Lin12A-B) and NB7–2(Lin11A-B). Refer to Table 2. for a complete list of hemilineage-specific TFs (45,71).

(D) Individual leg MNs belonging to hemilineage 24B from NB4–4, express unique combinations of morphological TFs (mTFs) that control their dendritic projections and axon targeting morphologies (56).
