The contractile function of pulmonary artery smooth muscle cells (PASMCs) was assessed by traction force microscopy on polyacrylamide gels of 6.4-kPa shear modulus. A: example of cell traction images for PASMCs from the 11–25 y/o subject group and 50–60 y/o subject group. B–D: the root mean square (RMS) traction was computed for individual cells (B) and analyzed for the 2 age groups considering all the measurements on a per cell basis (C) or by averaging results by subject (D). Bars show means ± SE with **P < 0.01.
