Oocyte specific lncRNA variant Rose influences oocyte and embryo development

Non-coding RNA Research, 2021
Fully grown mammalian oocytes store a large amount of RNA synthesized during the transcriptionally active growth stage. A large part of the stored RNA belongs to the long non-coding class which contain either transcriptional noise or important ...

Is It Possible to Expand Oocyte Donors by Decreasing Number of Oocytes for Own Use? Insights From a Large Single-Center Study

Frontiers in Endocrinology, 2021
BackgroundCurrently, in China, only women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles can donate oocytes to others, but at least 15 oocytes must be kept for their own treatment.

Review: Environment of the ovulatory follicle: modifications and use of biotechnologies to enhance oocyte competence and increase fertility in cattle

Animal, 2023
The oocyte is the basis of life, supporting development from a fertilized cell to an independent multicellular organism. The oocyte’s competence to drive the first cell cycles postfertilization are critical to embryonic survival and subsequent successful

Cdk1 inactivation induces post-anaphase-onset spindle migration and membrane protrusion required for extreme asymmetry in mouse oocytes

Nature Communications, 2018
Female meiotic divisions are asymmetric with the formation of large oocytes and small polar bodies, thought to result from cortical spindle placement before anaphase.

Oocyte Competence Biomarkers Associated With Oocyte Maturation: A Review

Frontiers in Cell and Developmental Biology, 2021
Oocyte developmental competence is one of the determining factors that influence the outcomes of an IVF cycle regarding the ability of a female gamete to reach maturation, be fertilized, and uphold an embryonic development up until the blastocyst stage ...
