Figure 4

The size of swirls scales with ν. The radius of the swirls is plotted versus the average ν for control (red circles), mild asthma (black squares) and severe asthma (blue diamonds) ALI cultures. The data for the trachea (green triangles) are from the literature^26,35. The size of the swirls scales with ν over 3 orders of magnitude, from R ~ 10 μm up to the radius of the ALI culture (R = 6 mm). Interestingly, the data for the trachea fall on the same curve.
