Mitochondrial profile densities and areas in different developmental stages of the sea urchin Sphaerechinus granularis
Mitochondrial profile densities in electronmicrographs were counted in the swimming blastula, mesenchyme blastula, gastrula and prism stages of the sea urchin embryos Sphaerechinus granularis. No numerical changes were statistically apparent. When profile areas were investigated, the mean values of...

| description | Mitochondrial profile densities in electronmicrographs were counted in the swimming blastula, mesenchyme blastula, gastrula and prism stages of the sea urchin embryos
Sphaerechinus granularis. No numerical changes were statistically apparent. When profile areas were investigated, the mean values of the swimming blastula, the gastrula and the prism stage showed no statistical differences. However, increased areas were measured in the mesenchyme blastula stage. This increase might be related to an increase of the embryonic volumina in the mesenchyme blastula stage. In contrast to earlier reported data, the results indicate that the mitochondrial density in
S. granularis embryos does not alter during development in these stages. |
