Comparison of time intervals from diagnosis to chemotherapy between patients opting for embryo cryopreservation or ovarian tissue cryopreservation.
University hospital in the Netherlands.
PATIENTS AND METHODS
Thirty-five female patients undergoing fertility preservation procedures before treatment with chemotherapy for cancer. Embryo ...
We review the history of the cryopreservation of human sperm. The current methods of cryopreservation and indications are highlighted, and the success rates of the various uses of cryopreserved sperm are reviewed. Potential adverse sequelae of human cryopreservation are also discussed.
MATERIALS AND METHODS
Indications for cryopreservation include several applications, namely homologo...
Cryopreservation has been a technique used in reproductive endocrinology and infertility medicine since the early 1980s. Embryo cryopreservation, specifically, has been widely used in many in vitro fertilization (IVF) programs worldwide. This method has been well studied and is a common strategy employed for storing supernumerary embryos after IVF cycles, among other applications. Oocyte cryopr...
Cryopreservation is hypothesized to result in apoptosis, contributing to stromal damage and follicle loss in ovarian tissue. This study investigated tissue viability following whole ovine ovary cryopreservation and examined the effects of the anti-apoptotic agent sphingosine-1-phosphate (S-1-P) on ovarian cryopreservation efficiency.
Whole ovine ovaries were cryoperfused an...

Several studies have shown that one of the sugars, trehalose, can improve tissue survival after cryopreservation when combined with other cryoprotective agents, and thus may possibly be used in cryopreservation of adipose tissues that have been found more resistant to injury after freezing.
The purpose of this study was to test our hypothesis that lipoplasty-derived adip...
Vitrification and slow-freezing methods have been used for the cryopreservation of human pluripotent stem cells (hPSCs). Vitrification requires considerable skill and post-thaw recovery is low. Furthermore, it is not suitable for cryopreservation of large numbers of hPSCs. While slow-freezing methods for hPSCs are easy to perform, they are usually preceded by a complicated cell dissociation pro...

Basidiomycetes have several biotechnological and industrial applications such as enzyme production, bioremediation, pharmaceutical and functional food production. Due to climatic features, the preservation of several basidiomycetes is threatened, and to guarantee the preservation of this genetic resource, the development of long-term preservation techniques is necessary once there is no univers...
Human pluripotent stem cell (hPSC)-derived cell therapy requires production of therapeutic cells in large quantity, which starts from thawing the cryopreserved cells from a working cell bank or a master cell bank. An optimal cryopreservation and thaw process determines the efficiency of hPSC expansion and plays a significant role in the subsequent lineage-specific differentiation. However, cryo...

Human embryonic stem (hES) cells have enormous potential for clinical applications. However, one major challenge is to achieve high cell recovery rate after cryopreservation. Understanding how the conventional cryopreservation protocol fails to protect the cells is a prerequisite for developing efficient and successful cryopreservation methods for hES cell lines and banks. We investigated how t...
Embryos and gamete cryopreservation contract is a contract between the embryos cryopreservation applicant and cryopreservation centers to freeze and preserve their embryos and gamete. This article aims to review constitutional conditions of validity, parties` obligation, sanction and dissolution methods of embryos and gamete cryopreservation contract. Research method has been revision in some p...
