The parameters of cell area, perimeter, circularity and number of skeleton ends are significantly different between 2 DAG and 5 DAG cells (t-test, p < 0.05). These parameters are significantly different between 5 DAG and 12 DAG cells as well (t-test, p < 0.05). These parameters are not significantly different between 12 DAG and 18 DAG cells.
