Figure 2 (IMAGE) The University of Hong Kong Caption Fig. 2. Demonstrated detection of the traction forces of the adhered cells. Three typical cells, namely the (A) well-spread cell, (B) less-spread cell and (C) cell-cell contacted cells were chosen to demonstrate the measurements: the first two columns show the transmitted light images and corresponding marked images; the third column shows the T1 mapping and the last column shows the line profile, as-marked in 2nd and 3rd column, of T1 value across the cell body. (D) T1 values changes in selected areas of cells.
