Preferred biological specimens according to the present invention are developmental cells.

La présente invention concerne un procédé de vitrification d'un spécimen biologique. Selon ce procédé, on expose un spécimen biologique directement à l'action d'un matériau de congélation, ce qui entraîne sa vitrification. Le spécimen biologique qui a subi une vitrification peut être conservé en l'état pendant un certain temps, puis être décongelé ultérieurement. Le spécimen décongelé reste viable. Les spécimens biologiques selon l'invention sont de préférence des cellules reproductrices ou embryonnaires.
