To elucidate a relationship between early cleavage planes and dorso-ventral (DV)-axis of sea urchin embryos, a fluorescent dye, Lucifer Yellow CH, was iontophoretically introduced into one blastomere at the 2-cell stage, and the location of the progeny cells was determined in the half-labeled prism larvae by examining the embryos from the animal pole. The boundary plane which divides the embryonic tissue into the labeled and nonlabeled parts was (1) coincident with, (2) perpendicular to, or (3… CONTINUE READING
