Failure of oocyte maturation: possible mechanisms for oocyte maturation arrest.
For human IVF, the patient's ovaries are hormonally stimulated to ensure the collection of fully matured oocytes that are at the metaphase II stage. Only these oocytes can be successfully fertilized either when mixed with sperm or after ICSI. Nevertheless, in some cases immature or maturing oocytes are recovered from follicles. Surprisingly, sometimes these oocytes do not complete maturation wh...
متن کاملOpsonic complement component C3 in the solitary ascidian, Halocynthia roretzi.
The recent identification of two mannose-binding lectin-associated serine protease clones from Halocynthia roretzi, an ascidian, suggested the presence of a complement system in urochordates. To elucidate the structure and function of this possibly primitive complement system, we have isolated cDNA clones for ascidian C3 (AsC3) and purified AsC3 protein from body fluid. The deduced primary stru...
متن کاملEmbryological Aspects of Oocyte In Vitro Maturation
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...
متن کاملNeural marker genes differently expressed in subsets of embryonic neural cells of the ascidian Halocynthia roretzi.
Ascidians are lower chordates that possess a possible prototype of the vertebrate nervous system. The central and peripheral nervous systems of ascidian larvae are composed of only a few hundred cells (Nicol and Meinertzhagen, 1991). To investigate how these ascidian nervous systems develop, dissection at the molecular level using subset-specific markers is essential. Here we describe four new ...
متن کاملIn vitro follicle growth supports human oocyte meiotic maturation
In vitro follicle growth is a potential approach to preserve fertility for young women who are facing a risk of premature ovarian failure (POF) caused by radiation or chemotherapy. Our two-step follicle culture strategy recapitulated the dynamic human follicle growth environment in vitro. Follicles developed from the preantral to antral stage, and, for the first time, produced meiotically compe...
