vang-1 transcripts can be detected in both the QL and QR neuroblasts at the onset of larval development. During the initial polarization and migration of the Q neuroblasts that precedes their response to Wnt ligands [35, 36], there is a clear increase in
vang-1 expression in both neuroblasts to an average of 4 ± 1.5 transcripts. After division, there is a significant decrease in
vang-1 expression in QL.p (1.5 ± 1 transcripts) and QR.p (1.5 ± 1 transcripts), but this expression remains relatively constant during QR.p and QR.pa migration.
