Figure 3. Each CX columnar neuron type arises exclusively from young or old INP lineages.

Figure 3.

(A–D) Columnar neuron cell bodies labeled by subtype-specific LexA lines derive from INP lineages (n = 5 for each experiment). Staining shows the volume containing cell bodies; thus most axon and dendrite projections are not visible. See Figure 1—figure supplement 1A for genetic details. (E–H) The PF-R and E-PG columnar neurons are generated by late INPs (n = 5 for each experiment), whereas the P-EN (n = 11) or P-FN (n = 6) neurons were not derived from old INPs and thus are fully derived from young INPs. Staining shows the volume containing cell bodies; thus most axon and dendrite projections are not visible. See Figure 1—figure supplement 1C for genetic details.
