Fig. 2. Quantitative analysis of cell spreading with and without STA and KT. Cells
treated with KT and STA started to spread much earlier than did cells without
these compounds (A). Quantitative measurements of cell areas clearly showed an
acceleration of the rate of cell spreading by STA and KT (error bars are
standard deviations) (B). The difference in the area of cell spreading with
and without STA and KT at 30 minutes is statistically significant
(P<0.05).
