Funchal, Madeira | Project: | REDECA | Conference: | XV Simpósio Ibérico de Estudos de Biologia Marinha (SIEBM 2008) | Abstract: | Early (previtellogenic) oocytes of deepwater crab Chaceon affinis show a high nucleus-cytoplasm ratio, a single nucleolus, and the nuclear envelope shows abundant nuclear pores. Small "nuages" are seen at the perinuclear cytoplasm. The cytoplasm contains ribosome-like particles, round mitochondria, and electron-clear vesicles. During vitellogenesis cytoplasmatic membrane inclusion proliferate. The cytoplasm also has multivesicular bodies and vesicles enclosing a dense granular core surrounded by an electron-clear matrix. | URI: | http://hdl.handle.net/10553/122693 | Source: | XV Simpósio Ibérico de Estudos de Biologia Marinha (SIEBM 2008): Funchal (Portugal), 09-13 de septiembre de 2008, p. 85 |
