Cryopreservation of biopsied embryos at the blastocyst stage.
BACKGROUND The availability of an efficient cryopreservation program is especially important in the case of embryos that have undergone blastomere biopsy for PGD. Unfortunately, the freezing/thawing of biopsied embryos has given disappointing results when performed at the cleavage stage. In this study, embryos diagnosed as normal after PGD were grown to the blastocyst stage, frozen and thawed f...
متن کاملOptimization of human peripheral blood mononuclear cells (PBMCs) cryopreservation
Cryopreservation is the method of choice for long term storage of human PBMCs. This study was designed to compare the different combinations of variables affecting the cryopreservation of PBMCs samples. The viability of PBMCs separated from 2×5 ml peripheral blood samples obtained from 16 healthy adult volunteers, were measured using trypan blue dye exclusion method just before freezing with ...
متن کاملCryopreservation of Human Mucosal Leukocytes
BACKGROUND Understanding how leukocytes in the cervicovaginal and colorectal mucosae respond to pathogens, and how medical interventions affect these responses, is important for developing better tools to prevent HIV and other sexually transmitted infections. An effective cryopreservation protocol for these cells following their isolation will make studying them more feasible. METHODS AND FIN...
متن کاملHuman Sperm Cryopreservation
As the demand for assisted reproductive techniques in humans increases, so does the demand for the oocytes and sperm that are essential for these techniques. Human sperm banks play a key role in assisted human reproduction, as a reservoir of sperm from the semen of donors and as an option for genetic preservation for some patients. There are different techniques that can be used to store human ...
متن کاملHuman oocyte cryopreservation.
The clinical role of oocyte cryopreservation in assisted reproduction, as an adjunct to sperm and embryo cryopreservation, has been comparatively slow to evolve as a consequence of theoretical concerns related to efficacy and safety. Basic biological studies in the 1990's alleviated many of these concerns leading to more widespread adoption of the technology. While a number of babies were born ...
