Biogenic monoamines in oocytes of echinoderms and bivalve molluscs. A formation of intracellular regulatory systems in oogenesis.
1. Identification of catecholamines and indolylakylamines in the fully grown oocytes or mature eggs of the representatives of echinoderms and bivalve molluscs was made using the fluorometric method. 2. Dopamine is the main catecholamine in the oocytes of all investigated animals. Tryptamine was the main indolylalkylamine. 3. The data presented confirm the presence of the main components of regulatory systems (transmitters, enzymes of their exchange, intracellular messengers, intracellular receptive systems) in the fully grown oocytes. 4. A hypothesis is proposed of the formation of intracellular regulatory systems (monoaminergic, cholinergic, peptidergic and steroidal) in oogenesis.
