Summary
Female genetics preservation using oocyte and embryo cryopreservation has advanced significantly in humans and cattle. However, challenges remain for broader application in other vertebrates, highlighting areas for future research.
Area of Science:
- Reproductive biology and cryobiology.
Background:
- Oocyte and embryo cryopreservation are key methods for preserving female genetics.
- Progress over four decades has been largely driven by research in humans, cows, and mice.
- Two main techniques, controlled-rate freezing and vitrification, dominate the field.
Purpose of the Study:
- To review advancements in oocyte and embryo cryopreservation.
- To discuss the major strides and obstacles in applying these techniques across different vertebrate species.
- To highlight the current status of cryopreservation in human medicine, the cattle industry, and laboratory animals.
Main Methods:
- Review of existing literature on cryopreservation techniques.
- Analysis of progress in human, bovine, and murine oocyte and embryo cryopreservation.
- Comparison of controlled-rate freezing and vitrification methods.
Main Results:
- Significant progress in human, bovine, and murine cryopreservation.
- Vitrification has gained prominence alongside controlled-rate freezing.
- Limited success in cryopreserving oocytes and embryos of most other mammals and vertebrates.
Conclusions:
- While cryopreservation is established for certain species, widespread application in other vertebrates faces significant hurdles.
- Further research is needed to overcome obstacles and improve success rates for a broader range of species.
- The review provides insights into the current state and future directions of vertebrate oocyte and embryo cryopreservation.

01:57Meiosis II
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each containing...
01:28Cryo-electron Microscopy
Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...
