Ontogeny of lens crystallins in marine cephalopods.

The ontogeny of the lens crystallin antigens throughout development of three marine cephalopod embryos, Loligo vulgaris, Sepia officinalis and Octopus vulgaris has been investigated using the indirect immuno-cytochemical staining against respective homologous anti-total lens protein antiserum. The cellular mechanism of lens development appears to be the same in all species investigated and so does the ontogeny of the lens crystallins. The first positive immuno-fluorescence reaction appears simultaneously and in equal intensities over the lens and lentigenic area confirming the relationship between the two.
