I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉 @karalmckinley.bsky.social We built the first transgenic model of menstruation in mice. We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪 www.biorxiv.org/content/10.1... 🧵

Induction of menstruation in mice reveals the regulation of menstrual shedding
During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

Preprint alert! We combined microfluidics, proteomics, and RNA-seq to map spatiotemporal protein expression during mouse somitogenesis and found a novel regulatory strategy: dynamic antagonistic gradients fine-tune signalling strength. doi.org/10.1101/2025...

We've updated our biorxiv! Check it out if you're interested in a new technique co-profiling RNA and epigenetics in single cells, extended gastruloid culture, and our proposed model for an epigenetic timer determining sequential perceptiveness to different lineages! ➡️ www.biorxiv.org/content/10.1...

Here it is! Bonsai. Now there is really no more excuse for using t-SNE/UMAP. Bonsai not only makes cool pictures of your data. It actually rigorously preserves its structure. No tunable parameters. Incredible work by @dhdegroot.bsky.social. I'm so excited about this! www.biorxiv.org/content/10.1...

Martino Ugolini and I wrote a review on how useful embryos are to understand the role of transcription bodies in gene expression. I am sure @mirlab.bsky.social, @harrisonflylab.bsky.social, @lennarthilbert.bsky.social and others would agree. Enjoy the read! portlandpress.com/biochemsoctr....

Query from Slack tankspace: “Looking for transgenic lines [preferably in Europe] marking mesoderm/mesendoderm and ectoderm, with expression before 6hpf. Thinking of mezzo and sox3, if anyone has these? Any other suggestions would also be great.” #AskZebrafish

How do embryos ensure precise tissue patterning? It’s all about timing cell divisions! Our new preprint reveals how cell proliferation syncs with signaling oscillations to regulate precision of somite formation and growth. Check the full story: www.biorxiv.org/content/10.1...
