Cell proliferation activity is measured as the average of BrdU-positive cells/unit area±s.d. and percentage of BrdU-positive cells divided by total number of cells per unit area.

The number of samples (n) analyzed is also shown. Numbers in parentheses indicate the average of the total number of cells per unit area.
