Fig. 2. Cell migration defects in ceh-20(-) and unc-62(-) mutants. The final positions of the QL.ap (left column) and QR.ap (right column) cells are graphed using the V cell daughters as reference points along the x axis, with left being anterior. The QL.ap cells in ceh-20(mu290) and unc-62(mu232) can be displaced anterior to the wild-type (WT) and mig-13(mu31) positions, but not as far anteriorly as in mab-5(e2088) animals. The QR.ap positions in ceh-20(mu290) and unc-62(mu232), as in mig-13(mu31) and lin-39(n1760) (although to a lesser degree in the latter), are significantly posterior to those found in wild type. The vertical gray line indicates the birthplace of the Q cells. The blue arrow indicates the total posterior distance that QL, QL.a and QL.ap migrate in wild-type animals. The pink arrow indicates the total anterior distance that QR, QR.a and QR.ap migrate in wild-type animals. n100 cells for each strain.
