SGGW scientists have obtained the world’s first bison embryo with in vitro

Specialists from the Warsaw University of Life Sciences have for the first time in the world obtained a bison embryo using the in vitro method. This is a major step toward securing a species whose future is still uncertain.

The research team at the Faculty of Veterinary Medicine at SGGW is headed by Professor Anna Duszewska. Her team also includes Dr. Pawel Grêda and Magdalena Baraniewicz, M.Sc. The coordinator of the project is Professor Wanda Olech-Piasecka, ktora is dean of the Faculty of Animal Sciences at the Warsaw University of Life Sciences and president of the Association of Lovers ofoin Bisonow.

– Six freshly downloaded comoovarian records we were able to fertilize with previously acquired sperm, whichore were unfrozen specifically for this purpose. This has already been a huge success, but of even greater significance is the fact that one of the embryonicow is still developing and is currently at the early blastocyst stage – explained Prof. Duszewska.

– This successful experiment opens up completely new possibilities. One of the elementsoin this program is the creation of a professional gene bankoin the bison, containing tissues, comoreproductive cells and, above all, embryos. Thanks to this, we will obtain a unique on a global scale security for the species, whichohe future of the population is still uncertain,” explained Prof. J. K. K., in turn. Olech-Piasecka.

– We are afraid, above all, of chorob infectious diseases, whichore appear in roEuropean locations and could annihilate our plans to move live bisonow. In such a situation, only embryos will make it possible to refresh the blood in the herds,” added Prof. Olech Piasecka.

„Construction of a gene bankow is one of the goalsoin the March 1 launch of the project for the comprehensive protection of the bison by the State Forests. Its other components include ongoing care and monitoring of the health of the existing population, the establishment of new bison herdsoin Poland and the spread of these animals around the world. The four-year project is worth more than 40 million zlotys and is entirely financed from the funds of theoin the Forestoin the State, i.e. from the forest fund” – We read on the pages of Lasoin the state.

– In the world, the in vitro embryo culture method has been used – successfully – in many species ofoin mammalianow. Now it has also succeeded in the bison, whichory is a species of particular interest to usoThe bison embryo was saved from extinction in Poland and restored in vitrooconfined to nature. All of the world’s living bison are descendants of only a few individualsoin – which means the so-called. low genetic variability. And yet anomalies do not appear in calves, which often happens when animals are mated in a large relationship – commented in an interview with PAP the director of the Institute of Mammalian Biologyoat the Polish Academy of Sciences in Bialowieza, prof. Rafal Kowalczyk.
