(A) Immunocytochemistry for SMA in CFs grown in serum free (SF) media or media supplemented with TGFβ-1 (10ng/ml), Y-27632 (10μM) or both TGFβ-1 and Y-27632. All images were captured using identical exposure settings. Scale bar = 25 μm.
(B) Immunocytochemical detection of Flag-tagged MRTF-A in CFs after 24 hours of growth in SF media or media supplemented with TGFβ-1, Y-27632 or both TGFβ-1 and Y-27632. Scale bar = 100 μm.
(C) Quantification of the subcellular localization of Flag-MRTF-A under various culture conditions. Subcellular localization of Flag-MRTF-A was scored for approximately 20 random fields of view for each condition. Error bars represent the SEM (* denotes p-value < 0.01; † denotes p-value < 0.05).
