(a) 1, 3 and 5-day hMSC proliferation with 3-min LIPUS (30 mW/cm2; 1.5 MHz; 20% duty cycle; 200 μs pulse length) and 0.5% MB suspension (Data are mean ± StdEM, n = 9). Microscopic images of hMSC growth two days after LIPUS (30 mW/cm2; 1.5 MHz; 20% duty cycle; 200 μs) pulse length). (b) Control, (c) LIPUS, (d) LIPUS with 0.5% (v/v) MB suspension. Values significantly different from the control group are indicated by *for p < 0.05 and **for p < 0.01.
