BrdU pulse and pulse-chase experiments with posterior regenerates at different time points. BrdU-labelled cells in green; mitoses in red; anterior is to the left. (A-H) BrdU pulse experiments are framed in white. (I-M) Pulse-chase experiments are framed in orange. (A-E) Pulse experiments reveal proliferation of BrdU-labelled cells at the posterior end (blastema) at 6 to 36 hours of posterior regenerates and show the reliance of the regenerating pharynx on proliferating cells around but never within its primordium (D-F). This absence of proliferation is highlighted by hollow arrowheads. (K-M) BrdU pulse-chase experiments showing the specific migration of BrdU-labelled cells into the pharynx primordium between 24 and 48 hours, indicated by white arrowheads. Asterisk in C denotes an artefactual red line. Scale bars, 100 μm.
