NB 3-1 delaminates at S3 in the medial column of NBs. It generates the well-characterized RP1,3,4,5 motoneurons and a cluster of intersegmental interneurons. It also generates a variable number of local interneurons.
Wherever possible we show movies with 2 or more clones, in order to show how the clones are arranged in relation to one another.
All clones are at stage 17, unless otherwise specified.
