A predominantly hypodermal cell expression pattern was displayed in the
fkb-3 and -5 lines. All lifecycle stages examined from mid-embryo through larval to adult stage displayed this hypodermal expression pattern. Both
fkb-3 and
fkb-5 share very similar expression patterns that included the lateral seam cells, tail, and head hypodermal cells. The observed expression pattern was consistent between the transgenic markers applied, namely hypodermal
rol-6 and neuronal Unc-76 rescue.
