Obtaining Wisent early blastocyst in vitro is a basic for protection and creation of biodiversity for this threatened species

Contents Wisent, or European bison (Bison bonasus), is listed as vulnerable on the IUCN Red List of Threatened Species and is therefore protected by international law. For the first time, a Wisent embryo has been obtained in vitro. This procedure creates a new opportunity to protect and increase Wisent reproductive potential and thereby opens new possibilities for the establishment of a controlled and broad reserve of the gene pool.
