Cell proliferation in anterior and posterior pieces of 3-day-old larvae. A) Representative pictures of cut and uncut bipinnaria larvae, B) quantitative analysis of cell proliferation activity. Sea star larvae were cut in half and fixed 2h and 24h later, after a 75 minute incubation with EdU (red). The nuclei were labeled with Hoechst (blue). Uncut larvae were used as a reference.
