Fluorescence microscopy images showing the effect of low dose of drugs on cell organisation and spreading on Ti surfaces after 24 h. Actin expression (green images) appeared more abundant in cells treated with the ALE and PAM (100 nM and 10 nM). Likewise, vinculin expression (red images) appeared more abundant in treated cells. Images were taken using a × 40 objective. Scale bar = 50 μM. SEM images were found to correlate with fluorescent images.
