Hydrodynamic behaviors of cells. (a) Force diagram of a particle in liquid flow. (b) m = F V/(F G − F B) as a function of U. (c) Particle Stokes number Stk = UρP d 2/18 μD of a 10-μm particle for various tube diameters D as a function of U. (d) Trajectory of a MSC carried by flow at U = 200 μm/s and (e) travel distances measured over 15 s. (f) Experimentally obtained (left) and simulated (right) trajectories of (i) 1-μm particle, (ii) 10-μm particle, and (iii) MSC settling without flow. (g) Settling velocities of a 10-μm particle and MSC determined experimentally.
