It has been shown that the isolation of sea urchin blastomeres before "pos-division adhesion" leads mainly to the formation of similar blastomeres at the stage of the 4th cleavage division, whereas after adhesion it results in the formation of microm

It was shown that local application of agonists of the 3rd type receptors SR57277A and quipazine into the interblastomere cleft of Paracentrotus lividus embryos evoked specific membrane currents. At the same time, ligands of 5-HT3-receptors specifica

Agonists of serotonin receptors generate specific inward currents in the cells of early embryos of sea urchin Paracentrotus lividus. Dose-dependent current generated by 5-HT3-agonist 5-HTQ shows complex volt-amperic characteristics with reversal pote

Classical neurotransmitters acetylcholine and biogenic monoamines act as multifunctional substances throughout the metazoan ontogenesis. A suggested cyclic scheme describes developmental changes of neurotransmitter functions from the oocyte maturatio

It has been shown that cytotoxic action of neuropharmacological drugs (transmitter antagonists) on early urchin embryos is reduced or abolished by cyclic nucleotides and sodium fluoride. Such a protective action differs in cAMP and dibutyryl analogs

The dated treatment of the early embryos of an irregular (flat) sea urchin Scaphechinus mirabilis by neuropharmacological drugs (anti-neurotransmitters) during one of the first four cleavage divisions results in the impairment of intercellular connec

Studies have been made on the binding of labeled ligands to beta-adrenoreceptor--3H-dihydroalprenolol (DHA) and 125I-iodocyanopindolol (ICP--in crude homogenate and subcellular fractions of toad embryos during cleavage divisions. Specific binding of
