Fig. 3. Tracking phenotypic transition in single cell stained with SiR-actin.
a, b A single A549 cell stained with SiR-actin after 14 h and 48 h of TGFβ1 addition respectively. c, d Extracted stress fiber image from (a, b), respectively. e, f Angular distribution and OOP values of the cells shown in (a, b), respectively. g Plot of OOP values of a live cell (shown in (a–f)) against time of TGFβ1 treatment (red). Multiple live-cell OOP trajectories (gray) against the time of TGFβ1 treatment. Scale bar: 16 μm.
