Oocytes store large amounts of proteins to support the earliest developmental stages. In @nature.com, the Leung group describes the structure of the cytoplasmic lattice in unprecedented detail. At least 13 different proteins assemble into a stable storage complex. hubrecht.eu/oocyte-storage-complex/

Excited to share our work on the structure and function of cytoplasmic lattices within mouse embryos. A collaborative effort with @niakanlab.bsky.social and work led by @kashishsingh.bsky.social and @inaharasimov.bsky.social . It is now out on BioRxiv: www.biorxiv.org/content/10.6...

Honored to receive the Carus Medal from the German National Academy of Sciences Leopoldina.

Very grateful to my lab and all collaborators - this recognition belongs to all of us. ✨

Apply to become a Preprint Editor Development

We are inviting experienced researchers to apply to become Preprint Editors, a new type of editorial role responsible for handling our 'In preprints' articles and forging links with preprint literature. #prepints

📢 OPEN CALL: Lay Summary Editor📢

Reproduction and Fertility is seeking a Lay Summary Editor to review author-written lay summaries, ensure clarity for non-specialist audiences, and provide feedback before publication.

Interested? Email your CV to raf@bioscientifica.com

Mitosis has a timing system. If chromosomes attach properly, cells divide on schedule and keep proliferating. If attachment is slow or incomplete, the delay is recorded — and daughter cells stop dividing.
We explore this link in our new preprint.

#Aging #Aneuploidy

Human eggs ‘rejuvenated’ in an advance that could boost IVF success rates Exclusive: Research suggests supplementing eggs with a key protein reduces age-related defects, raising hopes of improved IVF for older women

Our work on improving human egg quality was featured in @theguardian.com.
We hope this will help to make #IVF more successful and allow more couples to conceive. 💜

Human eggs must segregate their chromosomes with exquisite precision — yet errors rise with maternal age, causing miscarriage & infertility.
Our new article on @biorxivpreprint.bsky.social shows why chromosome cohesion fails in aging eggs & how to improve it.

We’re recruiting a Postdoctoral Researcher at OIST (Okinawa, Japan) to explore how mitotic stress shapes aging.

If you’re excited about cell biology, aging, and mechanistic discovery, we’d love to hear from you.

A versatile cohesion manipulation system probes female reproductive age-related egg aneuploidy - Nature Aging To study pathways that lead to aneuploidy during aging, the authors provide a system that enables cohesion protein depletion in mouse oocytes, mimicking effects that occur during aging. They uncover a...

We built a targeted protein degradation–based system to mimic reproductive age-related aneuploidy in young eggs - revealing how chromosome errors associated with female infertility arise with age. 🧬✨

A basal body microtubule singlet-to-doublet transition in Plasmodium male gametogenesis - Nature Communications Yang et al. use cryo-ET and resolve a unique native architecture of microtubule singlet-to-doublet transition in the basal body of Plasmodium. They reveal the key role of δTubulin and ε-Tubulin in thi...

We usually learn that centrioles/basal bodies are made of microtubule triplets. But our work on Plasmodium shows its basal body is built from singlets, which then mature into the doublets of a functional cilium. #TEAMTOMO www.nature.com/articles/s41...

BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 (thread 👇)

Structure and assembly of the A-C linker connecting microtubule triplets in centrioles Multiscale cryo-EM of centrioles reveals the structure and polymorphism of the A-C linker connecting microtubule triplets.

Huge congratulations to Wieczorek Lab PhD student Bin Cai and now-PI Jingwei Xu @xujwet.bsky.social on figuring out the surprisingly complex structure of the A-C linker crosslinking microtubule triplets in Tetrahymena basal body centrioles! www.science.org/doi/10.1126/...

Dick is one of the most thoughtful folks in cell biology--this is a must read for anyone interested in microtubules!
