The secret to our big brains? Going with the flow(Tissue fluidization)!

Miki Ebisuya @ebisuyamiki.bsky.social · 4d

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

🚨 New preprint!
We profile the transcriptome of the C. elegans distal tip cell: a persistent leader cell that invades basement membrane to shape the gonad.

Our dataset defines the molecular signature of invasive leader cells & uncovers new regulators of collective cell invasion.

Stage-specific transcriptomics of a leader cell reveals cell machineries driving collective invasion

Collective cell invasion underlies organ development, epithelial repair, and cancer metastasis. Leader cells remodel extracellular matrix, sense guidance cues, reorganize their cytoskeleton, and coord...

What do we see when looking at cells under the microscope? 👉Some are bigger than others, some are elongated and align with the neighbors & others seem to move. Cool, right? But wouldn't it be cooler to quantify these observations?
