The effect on blocking NM-IIA expression on fibroblast proliferation. NFs and KFs were pretreated with 40 μM of blebbistatin (A, B) or transfected with si-NM-IIA (C, D), followed by treatment with TGF-β for 24, 48, and 72 h. The CCK-8 assay was used to determine cell proliferation. (E) The scheme of how NM-IIA contributes to the pathogenesis of keloid. Color images are available online.
