Firsthand cigarette smoke alters fibroblast migration and survival: Implications for impaired healing

Abstract

Although it is known that high levels of cigarette smoke lead to cell death, little is known about the effects of low‐to‐moderate levels of smoke components that are found in vivo, such as those experienced by cells in tissues. Clinical studies and experimental data show that smokers heal poorly and are more prone to develop fibrotic diseases. Here we show the effects of first‐hand cigarette smoke on fibroblasts, cells that are critically involved in these processes. Using doses of smoke found in the tissues of smokers and a variety of cell and molecular approaches, we show that these doses of cigarette smoke do not cause cell death but rather stimulate fibroblasts to produce stress response and survival proteins such as interleukin‐8, PKB/Akt, p53, and p21 that in turn contribute to an increase in cell survival. In addition, smoke‐treated cells show a decrease in cell migration, which can be explained by the increased cell adhesion and alterations in cytoskeletal elements. We also show that these levels of smoke cause changes in mitochondrial morphology with a minimum loss of function and these changes are the result of exposure to reactive oxygen species. We conclude that the increase in cell survival may lead to a build‐up of connective tissue in the area of a wound, potentially leading to delayed healing and/or fibrosis and that the alterations in the cytoskeleton and in cell adhesion result in inhibition of cell migration, a process that could lead to nonclosure of the wound for lack of proper fibroblast migration to form the healing tissue.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
