epithelial resealing in the absence of injury not dependent on actomyosin purse-string

a new PNAS paper analyzing epithelial resealing in the absence of a "wound"! this paper shows that the closure of a gap in an epithelial cell monolayer does not require the purse-string mechanism and is more dependent on cell crawling/lamellipodia formation!
