Efficient vitrification of mouse embryos using the Kitasato Vitrification System as a novel vitrification device
BACKGROUND Currently, the cryopreservation of embryos and oocytes is essential for assisted reproductive technology (ART) laboratories worldwide. This study aimed to evaluate the efficacy of the Kitasato Vitrification System (KVS) as a vitrification device for the cryopreservation of mouse embryos to determine whether this novel device can be adapted to the field of ART. METHODS In Experiment...
متن کاملVitrification of immature bovine oocytes using glass micropipettes under normal or super-cooled LN Vitrification and thawing: Two vitrification solutions
Aim: To evaluate the developmental competence of post-thaw vitrified bovine cumulus-oocyte complexes (COCs) in vitro. Materials and Methods: A total of 129 COCs were cryopreserved using vitrification solution comprising of 15% ethylene glycol (EG) + 15% dimethyl sulfoxide (DMSO) + 0.6 M sucrose in medium TCM-199 with 10% FBS. Immediately, within a minute they are plunged into liquid nitrogen us...
متن کاملThermodynamic aspects of vitrification.
Vitrification is a process in which a liquid begins to behave as a solid during cooling without any substantial change in molecular arrangement or thermodynamic state variables. The physical phenomenon of vitrification is relevant to both cryopreservation by freezing, in which cells survive in glass between ice crystals, and cryopreservation by vitrification in which a whole sample is vitrified...
متن کاملHolographic Optical Elements for Holographic Stereogram Printers
A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...
متن کاملVitrification versus conventional cryopreservation technique
During in vitro fertilization treatment (IVF), a surplus of oocytes is produced which results in a surplus of embryos which must be preserved. Due to the recent tendency in ART treatment to transfer fewer embryos in order to avoid multiple pregnancies, partly a result of new laws and guidelines aimed at controlling the number of embryos to be transferred and the number of oocytes to be fertiliz...
