Main outcome of study (acc. to author)

As compared to the control sample the exposure to the static magnetic field resulted in a statistically significant increase in cell viability. However, the increase of cell viability after pulsed electromagnetic field exposure was not significant.
This fact can be utilized for clinical application of static magnetic field during in vitro cultivation of chondrocytes.
