A report on the fertilisation and early development in the sea Urchin

The primary objective of this study was to investigate fertilisation, cleavage and gastrulation in sea urchin embryos. It was found that a difference between room and 4^oC stored samples were obtained, with only 55% of the embryos reaching the plateus larvae stage. After 72h, cell death occurred in the 4°C stored samples. The parthenogenic embryos died, and didn't pass the blastula stage of early gastrulation. This paper addresses 4 main topics of sea urchin embryo development, including parthenogenesis and the interference of fertilisation.
