pak-1::gfp reporter was expressed in cells previously reported to express pak-1, including CAN neurons and ventral cord motor neurons. In addition to cells previously reported to express pak-1, this reporter was expressed at a low level in P5.p, P6.p, and P7.p vulval cell lineages during the L3 and L4 stages, consistent with cell-autonomous function.

pak- 1 expression is seen in the early embryo and continues throughout all stages of embryogenesis. Expression is highly localized to the hypodermal cells beginning in the bean stage and occurring through the 1.5-fold stage, which is consistent with the timing of HSN migration. The authors assume that these are hypodermal cells based on the pak-1 transcriptional reporter overlap with marked hypodermal cells. pak-1 expression is dramatically reduced in the 3-fold embryo and becomes restricted mainly to the CAN.

pak-1 is expressed in the hypodermal tissue before and during the HSN migrations, consistent with earlier PAK-1 expression pattern reports. Expression is restricted to the hypodermal tissue throughout embryogenesis beginning prior to HSN migration (bean stage) and during HSN migration (1.5-fold), and continues in the hypodermis during late embryogenesis (3-fold).
