Effect of a 5 min-long vibrational loading on the viability, proliferation rate, and morphology of L929 cells. a Viability and b doubling time of L929 cells that underwent vibrational loading for 5 min at fin = 10 Hz, 50 Hz, 100 Hz, 500 Hz, and 1,000 Hz. Results are expressed as mean ± SD (n = 3). Unstimulated cells were kept as controls, and their viability (100%) and doubling time (18 hrs) as baselines. c Representative SEM micrograph of L929 cells undergoing vibrational loading for 5 min at fin = 10 Hz, 50 Hz, 100 Hz, 500 Hz, and 1,000 Hz. Unstimulated cells were kept as controls. Larger background images were taken at × 1,500 (scale bar = 20 µm) and inset micrographs at ×7,000 magnification (scale bar = 5 µm)
