NB 2-1 forms during S4 and generates primarily local interneurons.

Clones derived from NB 2-1 are the same in abdominal and thoracic segments.This clone has developed to stage 17.

NB 2-1 clone

in the abdomen:

 

Four ways to view the same clones

upper left panel is a confocal z-series of DiI labeled clone; sections are 1.5 microns.

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.
