Analysis of cell proliferation. (A) BrdU-incorporated wing discs after X-ray irradiation in wild-type Drosophila (mwh/flr). Black spots show the areas with incorporated BrdU. Discs appear typical at each time point in the absence of irradiation (0 Gy) and post-irradiation (15 Gy). (B) The level of BrdU incorporation after irradiation. Wing discs were grouped according to the level of BrdU incorporation: +  +  + indicates the level of the non-irradiated stained disc shown in (A); +  + , + , and—indicate the discs at 3, 24, and 12 h after 15-Gy irradiation, respectively, shown in (A). Approximately 20 discs were observed and classified into four groups for each time point
