A paper on the mechanism for spindle assembly in oocytes has been published. The spindle is an apparatus that segregate chromosomes into the egg.

Yoshida et al revealed that a kinetochore-based mechanism promotes spindle assembly in oocytes. Such a mechanism is less functional in humans compared to mice. The findings are important for the understanding of chromosome errors in human eggs.
The project was jointly carried out with IVF Namba Clinic, Osaka City University, and Newcastle University.

Yoshida, S., Nishiyama, S., Lister, L., Hashimoto, S., Mishina, T., Courtois, A., Kyogoku, H., Abe, T., Shiraishi, A., Choudhary, M., Nakaoka, Y., Herbert, M. and Kitajima, T.S.
Prc1-rich kinetochores are required for error-free acentrosomal spindle bipolarization during meiosis I in mouse oocytes.

Seeking a Research Scientist

The Laboratory for Chromosome Segregation is seeking a Research Scientist. This call is part of the QMIN (Quiescence Manipulation and Investigation of Natural-hypometabolism) project, a center-wide project that started in the BDR at 2019. If you are interested, please contact to Kitajima.
