cells exposed to the e-liquids — or to blood collected from e-cigarette users shortly after vaping — are less viable and exhibit significantly increased levels of molecules implicated in DNA damage and cell death. The cells are also less able to form new vascular tubes and to migrate and participate in wound healing. The severity… Read More »
