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? I'm @juliaeckert.bsky.social. Let's explore some analysis software!‬

Many cells during development are exposed to caspase activation and yet survive. Why some die and not others ? We found out that the memory of previous caspase activation bias significantly later death comitment and bias death distribution and single cell decision www.biorxiv.org/content/10.1...

#Phosphofructokinase (PFK) is considered an irreversible glycolytic #enzyme. This study shows that #Trypanosomes are the only known organism to use PFK in the gluconeogenic direction under normal conditions, likely due to its compartmentalization within glycosomes @plosbiology.org 🧪 plos.io/43r84Qc

Hey #Drosophila community. What's your favourite UAS-based membrane marker for live cell #microscopy ? I previously tried mCD8-eGFP but it seems to be stuck in the ER... I can pretty much only see endo-membranes. This is not helpful, since I want to see cell outlines. Any suggestions, ideas?

1/14 “Epithelial” & “Mesenchymal” aren’t binary categories—they form a spectrum, or better yet, a multidimensional space. This becomes especially clear in collective cell migration, which often depends on a finely tuned degree of “mesenchymal-ness”. #cellbio #devbio #cellmigration
