Department of Embryology of St. Petersburg State University is one of the oldest scientific and educational centers for embryology and developmental biology in Russia. Among its graduates are leading specialists in the field of developmental biology and cell biology. While maintaining interest in the classical issues of embryology, the Department is now dealing with the most important problems of developmental biology. The staff of the department, consisting of specialists in the development of a whole set of multicellular organisms, is united by the idea of forming integral ideas about the mechanisms of embryogenesis, regeneration and other important biological phenomena. The focus of attention is on differential gene activity, selective intercellular interactions, proliferation and cell behavior during morphogenesis both in the norm and in various developmental defects.

Embryonic and larval development of teleost fishes: basic and applied aspects
Fish are a large group of aquatic animals, comprising more than half of the species composition of all vertebrates. The department's research on the development of these amazing animals includes: the study of the yolk syncytial layer in embryos and larvae of teleost fishes from different taxonomic groups with different oocyte organization; the normal development of whitefish, three-spined stickleback (Gasterosteus aculeatus), daubed shanny (Leptoclinus maculatus), including individual organs such as the thyroid gland and nervous system. In collaboration with VNIRO, the development of Nelma from blastula to early juvenile stages was characterized, with special emphasis on the digestive system and the yolk syncytial layer. These data formed the basis of three articles and a histological atlas (Kondakova, Bogdanova, 2024). In cooperation with the staff of the Karelian Research Center of the Russian Academy of Sciences and Norwegian researchers (UiT The Arctic University of Norway, Tromsø, Norway; The University Centre in Svalbard) a detailed study of the unique temporary structure of Leptoclinus maculatus - the lipid sac - was carried out. It is located in the abdominal cavity of the larvae and is a set of individual lipid-filled cavities/compartments. The inner layer of each compartment is a symplast with numerous large nuclei. The symplast is in contact with blood vessels. In addition, the development of the digestive system, heart, thyroid and gonads in L. maculatus was characterized.

Molecular and cellular mechanisms of regeneration and asexual reproduction in animals

+
Understanding the diverse cellular and molecular bases of regeneration and asexual reproduction in animals can help address one of the most intriguing questions in biology - why animals (including humans) vary in their ability to regenerate.
