Extended Data Fig. 10: Geometric morphometric analyses of the inhibition of the PCP pathway using a rho-kinase (ROCK) inhibitor in stage 31 skate embryos.

a. Schematic of the landmark design used in these analyses, including both landmarks (numbered red points) and semi-landmarks (small red points). b. Principal components analysis shows that specimen shapes cluster by treatment and stage. Points X and Y were used to generate the deformation grids showing the shape changes between the area of the PCA plot dominated by control (c) and ROCK-inhibited specimens (d). Note the inhibition of growth on the anterior region of the pectoral fin in the ROCK-inhibited specimens.
