Oocyte development, meiosis and aneuploidy.
Meiosis is one of the defining events in gametogenesis. Male and female germ cells both undergo one round of meiotic cell division during their development in order to reduce the ploidy of the gametes, and thereby maintain the ploidy of the species after fertilisation. However, there are some aspects of meiosis in the female germline, such as the prolonged arrest in dictyate, that appear to pre...
متن کاملTranscriptomic profiling of human oocytes: association of meiotic aneuploidy and altered oocyte gene expression.
The ability to identify oocytes with the greatest potential for producing a viable embryo would be of great benefit to assisted reproductive treatments. One of the most important defects affecting oocytes is aneuploidy. Aneuploidy is also closely related with advancing maternal age, a phenomenon not well understood. This study combined a comprehensive cytogenetic investigation of 21 oocytes wit...
متن کاملAlteration of gene expression in human cumulus cells as a potential indicator of oocyte aneuploidy.
BACKGROUND Human female meiosis is particularly error prone, leading to the generation of aneuploidy, a problem which increases dramatically with advancing age. Despite being of great clinical importance, the genesis of oocyte aneuploidy remains poorly understood. Cumulus cells (CCs) surround oocytes in antral follicles and play a crucial role in regulating their maturation. During this investi...
متن کاملMathematical modeling of human brain physiological data.
Recently, a mathematical model of the basic physiological processes regulating the cerebral perfusion and oxygen supply was introduced [Jung et al., J. Math. Biol. 51, 491 (2005)]. Although this model correctly describes the interdependence of arterial blood pressure (ABP) and intracranial pressure (ICP), it fails badly when it comes to explaining certain abnormal correlations seen in about 80%...
متن کاملDiscrimination of Human Cell Lines by Infrared Spectroscopy and Mathematical Modeling
Variations in biochemical features are extensive among cells. Identification of marker that is specific for each cell is essential for following the differentiation of stem cell and metastatic growing. Fourier transform infrared spectroscopy (FTIR) as a biochemical analysis more focused on diagnosis of cancerous cells. In this study, commercially obtained cell lines such as Human ovarian carcin...
