Siberian researchers measured fat content in cat embryos

Researchers from the Institute of Cytology and Genetics and Institute of Automatics and Electrometric (both belong to Siberian Division of Russian Academy of Sciences and are located in Novosibirsk) have tried out a new technique of evaluation of content and state of lipid (fat) droplets in frozen oocytes, ovocytes, and embryos of domestic cats (Felis catus domesticus). The basis of the approach is Raman spectroscopy. It is expected that the method can also be applied to other mammals. The preprint of the research article is shared on the server of academic publications on biologic topics bior

The content of lipid droplets in ovocytes and cells of embryos of most representatives of Carnivora order is quite high. Hence, they often lose the vitality after cryopreservation. At the same time, many large carnivorous such as a tiger or leopard, are pushed towards extinction. Hence, it is especially important to know the lipid composition of their gametal cells and embryos, as well as the changes upon cryo-conservation for efficient preservation of genetic material of these animals.
