Vitrification Of Equine Expanded Blastocysts, Fabian Andres Diaz
LSU Master's Theses
The cryopreservation of equine expanded blastocysts (>300 um) has been largely unsuccessful primarily due to the low permeability to cryoprotectants and the large size of the equine embryo. Mechanical alternatives may provide means to overcome the capsule barrier and the relative large embryo size. In this regard, multiple experiments were performed in this study to evaluate different approaches of capsule puncture and blastocoele fluid extraction with the objective to develop a cryopreservation protocol for Day 8 equine expanded blastocysts. In the first experiment, twenty-four Day 8 expanded blastocysts were exposed to standard equine embryo vitrification solutions following one- or …
