Pins homolog LGN regulates meiotic spindle organization in mouse oocytes

Cell Research, 2009
Mouse oocytes undergo polarization during meiotic maturation, and this polarization is essential for asymmetric cell divisions that maximize retention of maternal components required for early development.

Meiotic spindle, spindle checkpoint and embryonic aneuploidy

Frontiers in Bioscience, 2006
In mitosis, a spindle checkpoint plays important roles at the metaphase-anaphase transition to ensure the formation of a bipolar spindle, the completion of connecting chromosomes to microtubules and the alignment of all chromosomes at the spindle equator before initiation of anaphase.

Visualization and Examination of the Meiotic Spindle in Human Oocytes with Polscope [PDF]

Journal of Assisted Reproduction and Genetics, 2004
The effect of detectability/location of meiotic spindle to fertilization of human MII oocytes and outcome of clinical IVF/ICSI-ET cycles was studied.The location of spindle relative to polar body positioned to 6 o'clock was detected with polscope prior to ICSI in oocytes.

Effects of cryopreservation on the meiotic spindle of human oocytes

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2004
The microtubular meiotic spindle of most mammals, including humans, is very sensitive to cooling [Hum. Reprod. 16 (2001) 2374; Fertil. Steril. 54 (1990) 102; Fertil. Steril. 75 (2001) 769; Zygote 3 (1995) 357] and is rapidly depolymerised even after a slight reduction in temperature to 33 degrees C.

mInscuteable regulates meiotic spindle organization during mouse oocyte meiotic maturation

Zygote, 2019
SummaryEstablishment of cellular polarity is one of the key events during oocyte maturation. Inscuteable (Insc) has been identified as a key regulator of cell polarity during asymmetric division in Drosophila. However, the function of its evolutionarily conserved mammalian homologue, mInscuteable (mInsc), in mouse meiotic maturation is not clear.
