Role of serotonin in vertebrate embryo development

Jessica Romero-Reyes et al. Reprod Biol. 2021 Mar.

Abstract

Since its discovery in 1937, serotonin (5-HT) has become one of the most studied biogenic amines due to its predominant role in regulating several physiological processes such as mood, sleep, and food intake. This amine and the main components of the serotoninergic system are in almost all cells of the body. The presence of 5-HT and the serotoninergic system has been observed in oocytes and in different embryo development stages of fish, amphibians, birds, and mammals. In several classes of vertebrates, the change in the concentration of 5-HT or the alteration of the serotoninergic system, interfere with early embryo development. These data suggest that 5-HT participates in embryo development of vertebrates.
