Augmin promotes meiotic spindle formation and bipolarity in Xenopus egg extracts

, 2011
Female meiotic spindles in many organisms form in the absence of centrosomes, the organelle typically associated with microtubule (MT) nucleation.

Inward transport of organelles drives outward migration of the spindle during C. elegans meiosis

Cell Reports
Summary: Cortical positioning of the meiotic spindle within an oocyte is required to expel chromosomes into polar bodies to generate a zygote with the correct number of chromosomes. In C.

Rac Activity Is Polarized and Regulates Meiotic Spindle Stability and Anchoring in Mammalian Oocytes

, 2007
SummaryMammalian meiotic divisions are asymmetrical and generate a large oocyte and two small polar bodies. This asymmetry results from the anchoring of the meiotic spindle to the oocyte cortex and subsequent cortical reorganization, but the mechanisms ...

NET1 is a critical regulator of spindle assembly and actin dynamics in mouse oocytes

Reproductive Biology and Endocrinology
Background Neuroepithelial transforming gene 1 (NET1) is a RhoA subfamily guanine nucleotide exchange factor that governs a wide array of biological processes. However, its roles in meiotic oocyte remain unclear.

NEDD1 is crucial for meiotic spindle stability and accurate chromosome segregation in mammalian oocytes

, 2010
Defects in meiotic spindle structure contribute to chromosome segregation errors leading to genomic instability in oocytes and embryos upon fertilization. In this study, we analyzed the mechanisms that control spindle microtubule nucleation and stability

Relationship between visualization of meiotic spindle in human oocytes and ICSI outcomes: a meta-analysis

, 2009
The objective of this meta-analysis was to investigate the influence of meiotic spindle visualization in human oocytes on intracytoplasmic sperm injection (ICSI) outcomes. Search strategies included on-line Surveys of databases (MEDLINE, em BASE, Science
