Table 3 Linear regression analysis of cell area, perimeter and single segment changes from 3 DAG to 5 DAG using time-lapse images

Field	R²(area) ⁽¹⁾	R²(perimeter)	R²(segments)	IF (%) ⁽²⁾	Growth rate (%/hour) ⁽³⁾
1 (N = 6)	0.999	0.999	0.963 ± 0.030 ⁽⁴⁾	91 ± 3 ⁽⁵⁾	1.89 ± 0.26 ⁽⁶⁾
2 (N = 4)	0.998	0.996	0.991 ± 0.007	89 ± 4	1.11 ± 0.18
3 (N = 5)	0.975	0.992	N.D. ⁽⁷⁾	88 ± 2	1.42 ± 0.24

⁽¹⁾ R² represents the R-squared values in linear regression analysis of surface area, cell perimeter, and anticlinal wall segment lengths plotted for populations of cells at 3 and 5 DAG. All p values are smaller than 0.01 during regression analysis.
⁽²⁾ IF: Isotropy Factor is calculated as the overlap between digitally isotropically amplified 3 DAG cells and the real cell imaged at 5 DAG.
⁽³⁾ Growth rate was calculated as ((5 DAG area - 3 DAG area)/(3 DAG area * 48))*100%
^(4), ⁽⁵⁾ ^{, (6)} Mean ± SD
⁽⁷⁾ N.D. Not determined
