To Walters, meeting the technical challenge of cryopreserving
the elm is crucial to the laboratory's overarching mission, which is to safeguard not only important plant genetic resources, but also those of animals and microorganisms.
They also discuss the normal physiology of folliculogenesis and the effect of stimulation; the use of oral contraceptives, clomiphene citrate, gonadotropin-releasing hormone antagonists, and aromatase inhibitors; endometrial receptivity; follicular aspiration and flushing; single embryo transfer; cryopreserving
techniques; patients with poor ovarian response and those at risk for ovarian hyperstimulation syndrome; low cost IVF for developing countries; a case study of one fertility center; and other aspects.
Therefore, in early 2005, opinion articles as well studies initiated to underline that vitrification might be a better alternative for cryopreserving
human zygotes and embryos rather than the slow-rate method (9 - 15).
the embryos from the first cycle and using them for later cycles fully uses the potential of the first oocyte retrieval, while allowing all the embryos resulting from that cycle to be used rather than discarded (Jones et al., 1997; Schnorr et al., 2000; Edgar et al., 2005).
The researchers aim to break down and automate many of the labor-intensive procedures, such working with biopsied material, preparing cells for stimulating growth, and cryopreserving
or packaging the new tissue for shipment.
ABSTRACT In this study several parameters critical to the success of cryopreserving
Sydney rock oyster (Saccostrea glomerata) larvae were investigated.
A further challenge is the prospect of cryopreserving
the bodies of persons who have been declared dead, in the hope that future technological developments will allow such frozen bodies to be thawed, repaired, and thereby reanimated.
A growing number of Americans now opt to bank their cord blood at own expense, cryopreserving
it at a private US facility for the family's exclusive use in the event of an unforeseen medical emergency.
-- The BioArchive System, an automated cryogenic device, is used by cord blood stem cell banks in more than 25 countries for cryopreserving
and archiving cord blood stem cell units for transplant.
When considered in combination with a voluntary embryo donation program, it seems wise to allow [in vitro fertilization] couples the option of cryopreserving
supernumerary embryos and donating them when no longer needed," no matter how long the time period, the authors said.
The primary objective of the study is to determine the efficacy of ViaCyte for the cryopreserving
and thawing of human oocytes.
sperm stem cells could help investigators store the genetic material of endangered species or animals that might be useful in research or agriculture.
