  • Numbers in bold indicate percentage of embryos showing expression in the neural lineages (Ci-Snail and Ci-Delta2), or the average number of A-line neural cells showing expression (Ci-ETR) following the treatment indicated at the top.

  • A , expression in A8.15/A8.16 blastomeres (Ci-Snail and Ci-Delta2), or the entire A-line neural lineage (Ci-ETR).

  • b , expression in b6.5 descendants (Ci-Delta2 only).

  • n , number of embryos analysed.

  • e , number of independent experiments.
