From: Ultrasound stimulation increases proliferation of MC3T3-E1 preosteoblast-like cells
Change in proliferation of MC3T3-E1 cells with ultrasound frequency. Change in proliferation of ultrasound stimulated MC3T3-E1 cells (normalized with control) at excitation frequencies of 0.5, 1.5, and 5 MHz with US intensity = 75 mW/cm2 (SATA), PRF = 1 kHz, pulse duration = 200 μs, and exposure time = 10 min. Values that are significantly different from control group have been indicated by for p < 0.05.
