An ovarian follicle poised for ovulation, with the oocyte at its centre. Cell membranes are shown in orange and DNA in blue.

How does an ovarian follicle remodel in space and time to release an egg? 💥🥚

We have an exciting PhD project combining follicle culture, advanced imaging and quantitative analysis to understand the cellular dynamics of ovulation. 🔬

Co-supervised by me and @guignardlab.bsky.social. Please share! 🌱

This looks remarkable!! Building my favorite subcellular structure from the ground up--WOW!!

Add me please.

The sarcomere is the elementary contractile unit of muscle, driving all volunatry motion and heart beat in animals. How these “cytoskeletal crystals” self-assembly is only partly understood.

🏋️Our review on how to build muscle is out in
@biophysicalreviews.bsky.social: The Physical Basis of Sarcomere Assembly. We critically review past models and discuss a new mechanism that unifies past ideas, suggesting tension-driven self-organization. With
@frankschnorrer.bsky.social & Kolley-Köchel

Experimental structures provide valuable hypotheses and accelerate but do not replace evolutionary and statistical analyses of protein sequences

Cell fun 🤭

Seen on way back to London from ASCB. As Jez Carlton said “if rudder falls off will it regenerate”. Have a good flight home everyone after another great meeting…… long may ASCB continue
