A Report on the Fertilisation and Early Development in the Sea Urchin

Abstract

The primary objective of this study was to investigatefertilisation, cleavage and gastrulation in sea urchin embryos.It was found that a difference between room and 4o C storedsamples were obtained, with only 55% of the embryosreaching the plateus larvae stage. After 72h, cell deathoccurred in the 4o C stored samples. The parthenogenicembryos died, and didn’t pass the blastula stage of earlygastrulation. This paper addresses 4 main topics of sea urchinembryo development, including parthenogenesis and theinterference of fertilisation.
