NB 3-3 delaminates at S4 and generates intersegmental interneurons as well as a cluster of local interneurons.

In 2/3 abdominal segments, we observe a motoneuron that innervates muscle 5.

NB 3-3 in thoracic segments at stage 16.

We find the presence of two egg-shaped cells to be absolutely characteristic of the NB 3-3 clone. There are contralateral intersegmental interneurons as well, and a small number of local interneurons. Occasionally we observe ipsilateral local projections, as seen here.

 

Four ways to view the same clones

upper left panel is a confocal z-series of DiI labeled clone; sections are 1.5 microns. Movie begins at dorsal surface of clone.

upper right panel is a projection of z-series, rotated 45 degrees about y-axis. DiI alone.

lower left panel is a confocal z-series of DiI-labeled clone in en-GFP background.

lower right panel is a projection of the z-series, rotated 45 degrees about y-axis. DiI with en-GFP.

In all cases, anterior is up.
