Expression of the Sipks (a) and Sisult (b) genes in spermatozoids (Sp), unfertilized eggs (Egg), coelomocytes (Cel), ambulacra (Ambl), embryos, and larvae of the sea urchin S. intermedius at various stages of development: blastula, 14 hpf (Bl), gastrula, 24 hpf (Gl), prism, 34 hpf (Pr), and pluteus, 72 hpf (Pl). * ; ** .
