How cells decide where to go? #CellMigration
Last year we published our 1st paper @cellcommlab.bsky.social, showing how actin-based membrane oscillations define a new direction ( #cancer & non-cancer #cells )

Cell migration is a key cellular process that drives major developmental programs and diseases.
Different assays have been developed, but they are often used interchangeably.
In our new paper, we describe how to select the optimal assay.
