Patent

CA 2435857

Provided herein are methods of managing embryo transfer programs, for instance bovine embryo transfer programs. Examples of such methods are referred to as "bred recipient transfer" programs, in which embryos (e.g.,. clonal embryos) are transferred to recipients that have been impregnated. Also provided are methods of enhancing survival of clonal embryos, in which the clonal embryos are transferred to bred recipients, and methods of increasing delivery success rates for cloned animals. Methods of serial transfer of embryos to a recipient, when that recipient returns to heat after an unsuccessful transfer, are provided. Finally, specific methods are provided for cloning male mammals, using diploid differentiated cells taken from a semen sample.

L'invention concerne des méthodes de gestion de programmes de transfert d'embryons, notamment de programmes de transfert d'embryons bovins. Des exemples de ces méthodes appelées <= programmes de transfert aux receveurs pleins >= consistent à transférer des embryons (par exemple, des embryons clonés) aux receveurs déjà imprégnés. Par ailleurs, l'invention concerne des méthodes d'amélioration de la survie d'embryons clonés, dans lesquelles ceux-ci sont transférés aux receveurs pleins, ainsi que des méthodes d'augmentation du taux de réussite de la mise bas d'animaux clonés. L'invention concerne également des méthodes de transfert en série d'embryons à un receveur entré de nouveau en chaleurs après un transfert non réussi. Enfin, l'invention concerne des méthodes spécifiques de clonage de mammifères mâles, faisant intervenir des cellules diploïdes différentiées provenant d'un échantillon de sperme.
