Figure 1

F-actin staining of human dermal fibroblast on micropillars with heights 4 µm (A), 8 µm (B) and 18 µm (C). Scale bar 20 µm. Cell spreading area (D) defined as the area of F-actin was quantified by Image J. (n = 10) SEM images were taken of micropillars with heights 4 µm (E), 8 µm (F) and 18 µm (G). Scale bar 50 µm.
