Read about a study led by BDR's Tomoya Kitajima showing that a protein-based artificial #kinetochore they developed can serve as decoys to relieve pulling forces acting on #chromosome pairs in dividing aged mouse #oocytes to prevent premature segregation.

It was a tough #poster design session last night! 😆
Next week I'll be at the @embo.org "Structure and function of the cytoskeleton" #meeting in #Paris, where I'll discuss the actin-dependent regulation our favorite #super-organelles in #oocytes.

A warm welcome to Roni, who joined the Schuh lab in December 2025 as a new Postdoc! She completed her PhD in Genetics focusing on the development and aging of #oocytes in C. elegans.
Now she‘ll investigate the role of actin in #meiosis.
Great to have you with us, Roni 🎉

🧫 Intracytoplasmic sperm injection (ICSI) has been widely used in assisted reproduction for #malefactor #infertility but this technique can place significant mechanical stress on #oocytes, sometimes leading to degeneration and reduced #embryo quality.
This week, we cover the latest work from Gameto!
Their Fertilo platform improved the in vitro maturation of human #oocytes. 🥚

The #cellbio2025 is starting this week! I’ll be giving a talk on the first 1st day, in the session organized by @iaincheeseman.bsky.social and @abbybuch.bsky.social (Thx for the invitation!). If you’re interested in #oocytes, #proteostasis, and #aging come by to attend! @ascbiology.bsky.social
☕Zhou et al. design protein-based artificial #kinetochore constructs as decoys to prevent premature #chromosomal separation in aged #oocytes. These constructs compete with chromosomal kinetochores, reducing excessive bipolar #microtubule pulling forces.

🥚As proof of concept, #oocytes were successfully collected from six euthanised koalas within two hours post-mortem, showing potential for the development of #genomebanks to support the species’ recovery.

🧬Why does female fertility decline with age? And can egg cells be rejuvenated🥚?

This is couple of years old since I rarely have time to sit at a scope these days but I was inspired by the end of year #FluorescenceFriday posts on hear and thought I should drop on y’all my Eye of Sauron, aka a mouse oocyte containing nuclear actin filaments #actin #meiosis #oocytes
#NCB2024
In June, Schuh & co analyzed #proteostasis in mammalian #oocytes and ovaries: found that the maintenance of oocytes involves exceptional protein #longevity, and many of the extremely long-lived proteins decline as the ovary ages.
