Fig. 5: Growth rate, area, and arrangement of cells in long-term culture (60 h) under 15% mechanical stimulation.
From: Strain sensor on a chip for quantifying the magnitudes of tensile stress on cells
a Bright-field images (Scale bar: 100 μm) of the control group and stimulation group at different culture times (24 and 60 h). Statics chart of cell orientation angle and length of the cell’s vertical axis. b Cell number growth rate between the control group and the stimulation group at different culture times (24 h, 36 h, 48 h, and 60 h). c Comparison of cell area growth rate between the control group and the stimulation group at different culture times (24 h, 36 h, 48 h, and 60 h). d Cell area growth rate between the control group and the stimulation group at different culture times (24 h, 36 h, 48 h, and 60 h)
