Embryo Cryopreservation

open access: yesSeminars in Reproductive Medicine, 1998
Cryopreservation stands as an ongoing evolution in the field of assisted reproductive technologies. Face with increasing numbers of fertilized oocytes and early embryos, cryopreservation avails the ART program of a useful means to preserve embryos for future use without exposing patients to the risks of multiple pregnancies.

Oocyte cryopreservation

Fertility and Sterility, 2006
To review historical and contemporary advances in oocyte-cryopreservation techniques and outcomes.Publications related to oocyte cryopreservation were identified through MEDLINE and other bibliographic databases.Oocyte cryopreservation can be used as an adjunct to conventional IVF and as an option for fertile women to electively cryopreserve their ...

Cryopreservation of Organoids

Cryoletters, 2023
Organoids represent indispensable opportunities for biomedicine, including drug discovery, cancer biology, regenerative and personalised medicine or tissue and organ transplantation. However, the lack of optimised preservation strategies limits the wide use of organoids in research or clinical fields.

Cryopreservation of cartilage

International Orthopaedics, 1990
We have investigated the viability and function of cells in cartilage slices after various methods of preservation, and have examined the viability of cells by measuring the incorporation of Na2(35)SO4 at different concentrations, temperatures and times of exposure to cryopreservatives.

The cryopreservation of Chlamydomonas

Cryobiology, 1979
A cryophilic strain of the unicellular green alga Chlamydomonas, C. nivalis was found to be more resistant to the stresses both of freezing and thawing and of shrinkage and rehydration than was a mesophilic strain C. reinhardii. C. nivalis was found to have a higher degree of unsaturation of phospholipid fatty acids. Following freezing and thawing of C.

Cryopreservation

British Medical Bulletin, 1990
Embryo cryopreservation is now firmly established as a routine component of in vitro fertilization (IVF) and other assisted conception techniques for the resolution of human infertility. Excess fertilized oocytes and embryos can be preserved for infertile couples avoiding the necessity to replace large numbers of embryos which reduces the incidence of ...

Cryopreserved bioprostheses

IEEE Engineering in Medicine and Biology Magazine, 1989
The process of cryopreservation is described. Three types of tissue are then considered: allograft heart valves, allograft veins and the musculoskeletal soft tissues of the knee. The problems with each of these tissue types are examined.

Cryopreservation of Cells

Current Protocols in Immunology, 1997
AbstractLaboratories interested in working with in vitro cultured cells must be able to freeze and thaw cell lines. Such capabilities are necessary to maintain the constancy of the cells since prolonged culture may result in phenotypic and genotypic changes. In addition, cell freezing minimizes problems with contamination as well as the overall expense

Survey on Cryopreservation

Annals of the New York Academy of Sciences, 1988
In this survey on cryopreservation of human embryos and oocytes, the results from 24 groups that reported replacements of cryopreserved embryos by the end of 1986 were summarized. So far 163 pregnancies have been reported, 65 children have been born, and 61 pregnancies were ongoing at the time of tabulation.
