Summary: This study evaluated the effect of different vitrification and warming processes on the in vitro survival of caprine morulae. The results showed that a successful embryo survival was achieved by using a combination of glycerol and ethylene glycol with the addition of sucrose in the vitrification process. The embryo survival rate was influenced by the day of recovery and the warming process.

Summary: This study compares obstetric outcomes in cancer patients who undergo cryopreservation of reproductive cells or tissues before gonadotoxic therapy. The results indicate that cryopreservation of oocytes, embryos, and ovarian tissue has similar effectiveness in terms of clinical pregnancy and live birth rates. However, ovarian tissue cryopreservation is associated with a significantly lower miscarriage rate compared to embryo cryopreservation.

Summary: Cryopreservation of embryos is crucial for assisted reproductive technology, but the increasing number of cryopreserved embryos poses challenges for disposition and donation. This series of articles discusses the medical potential of donated embryos, the practice of embryo donation, the management of embryos designated for disposal, and the legal environment of unused embryo management.

Summary: This meta-analysis investigates the impact of recryopreservation on embryo viability and the outcomes of in vitro fertilization (IVF). The findings suggest that recryopreservation can result in decreased embryo survival, clinical pregnancy rates, and live birth rates compared to single cryopreservation.

Summary: To conserve the important species of bison in Europe and North America, conservation efforts have focused on establishing sustainable herds through the use of assisted reproductive technologies (ARTs). These technologies facilitate the transfer of genetics and offer protection against future losses of genetic diversity. Research on ART for bison has made progress, but there are still opportunities for improvement and expanding their impact on bison conservation.

Summary: Vitrification-based cryopreservation is a promising approach for long-term storage of biological systems. By improving cooling rates and viability, it can be used to cryopreserve new biosystems. The use of conduction-dominated cryomesh has shown improved outcomes in vitrifying various biosystems, demonstrating its potential for scalability in biorepositories and other applications.

Summary: A study on ovarian cryopreservation and transplantation in a murine model showed a decrease in oocyte numbers, abnormal endocrine function of ovarian grafts, dysfunctional mitochondria and DNA damage in the oocytes after transplantation. However, these adverse phenotypes were partially or completely resolved within 21 days of transplantation.

Summary: The study demonstrates that multiple cryopreservation-warming cycles, coupled with blastocyst biopsy, have a negative impact on IVF outcomes, including reduced live birth and clinical pregnancy rates. However, there was no significant difference in miscarriage rates between the groups. Therefore, caution should be exercised when considering further embryonic micromanipulation after cryopreservation.

Summary: The study aimed to evaluate the efficacy of the transportation process for cryopreserved embryos and compare the survival rate and competence of transported embryos to those produced on-site. The results showed that the transportation of cryopreserved embryos did not affect embryo survival rate or in vitro fertilization outcomes.

Summary: This study investigated the changes in gene expression in fish larvae hatched from fresh and cryopreserved embryos for the first time, revealing significant effects on central nervous system development and cell structure due to cryopreservation. The results contribute to the construction of genome and proteome databases for kelp grouper, providing valuable insights for understanding the impact of cryopreservation on fish embryos and exploring the molecular mechanisms of cryoinjury.

Summary: This study developed an efficient method for hMSC proliferation and differentiation using gravity-controlled environments. The results showed that hMSCs cultured in microgravity conditions had a shorter doubling time and expressed hMSC markers. Additionally, osteogenic and adipogenic differentiation of hMSCs was enhanced under microgravity and hypergravity conditions, respectively.
