An oocyte is a female germ cell involved in reproduction, produced in the ovary during female gametogenesis. Learn about its formation, characteristics, maternal contributions, and role in fertilization and development.
Oocyte-specific deletion of Gsα induces oxidative stress and deteriorates oocyte quality in mice "The stimulatory heterotrimeric Gs protein alpha subunit (Gsα) is a ubiquitous guanine nucleotide-binding protein that regulates the intracellular cAMP signaling pathway and consequently participates in a wide range of biological events. In the reproductive system, despite Gsα being associated ...
An oocyte is a female germ cell in the process of development. Structure. Cytoplasm: Oocytes are rich in cytoplasm, which contains many types of molecules necessary to nourish the cell at the beginning of development. Nucleus: During the primary stage of oocytes in oogenesis, the nucleus is called the germinal vesicle. Mitochondria: The oocyte receives the mitochondria of the maternal cells ...
Learn about oocyte biology, development, and function from various chapters and articles in immunology and microbiology. Explore topics such as oogenesis, folliculogenesis, oocyte maturation, reprogramming, and cloning.
Learn about oocyte, the female gamete that undergoes meiosis and fertilization to form an embryo. Explore chapters and articles on oocyte quality, gene expression, telomere dynamics, and more.
Oocyte is a female gamete or sex cell that can develop into a new individual when fertilized by a sperm. Learn about the stages of oocyte maturation, the differences between primary and secondary oocytes, and the terms related to oocyte donation and retrieval.
Definition noun, plural: oocytes (1) A female gametocyte. (2) A developing female germ cell. Supplement The oocyte is an immature female sex cell. It starts off as an oogonium by the process of oocytogenesis, and matures to give rise to a fully mature ovum or egg cell and ootid (by ootidogenesis). In humans, the oocytes are of two types:
Oocyte is an immature egg cell that develops into an egg in animals. Learn about oocytes in different species, their structure, function, and role in reproduction from Britannica articles.
Oocyte maturation is the process that creates the fully mature gamete whose fate hangs on timely fertilization after ovulation. The cell is suspended between mortality and the possibility of producing virtually unlimited numbers of progeny. Maturation is triggered by the gonadotropin surge that occurs in the middle of a woman's menstrual ...
This article reviews the criteria and methods for evaluating oocyte quality based on morphological features. It discusses the factors that influence oocyte maturation and competence, and the limitations of morphological assessment in predicting embryo development.
