In situ assessment of cell functions on N2/Ar micro‐plasma exposed fibroblast cells is examined to better understand the effect of atmospheric low‐dose plasma treatment. The cells number increased threefolds for plasma exposure time of 5 or 10 s, followed by cell culture for 48 h. The cell coverage rate rose 20% for the same plasma exposure time, followed by cell culture for 6 or 12 h. 0.5% N2/Ar micro‐plasma exposure can particularly be used to achieve the stimulated release of FGF7 and subsequent enhancement of cells proliferation and migration. This work thus provides a potential of using micro‐plasma system for cells related studies and the improvement of cutaneous wound healing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
