Epithelial cell specialization at a limb segment boundary in the grasshopper embryo.
Epithelial cells at the developing femur-trochanter limb segment boundary in the grasshopper embryo are specialized with respect to nonboundary cells. They are elongated, with the long axis oriented along the limb circumference. Some cells along the boundary preferentially bind an antibody (anti-HRP), and so are molecularly specialized as well. The specialized cells are the most proximal cells of the more distal segment.
