Fate of BrdU-labelled cells after 3-day chase in sublethally irradiated animals. In all images, anterior is to the left (e eyes, mo mouth opening). a, a’ Animal with recovered stem cells in all regions showing a homogeneous distribution of BrdU-labelled cells. Note that differentiated BrdU-labelled cells migrated towards the midline and into the rostrum (region anterior to the eyes. b–d’ Partial recovery of cell proliferation. e-f’ Lack of somatic stem cell recovery; BrdU labelled cell are present only within the gonads.
