Details of stage 5 and blastema development of regenerating Syllis malaquini. a. Regenerated proventricle and pharynx (bisection at L2 + L3); arrowheads point to proventricular plates on the anterior portion of proventricle. b. Regenerated posterior end (bisection at L2); arrowhead points to urinary concretions. c. S-phase cell distribution during anterior regeneration of an amputee cut at L2 + L3, epidermal cells are on the border of the blastema, endodermal cells are centrally located in the blastema. d. Proliferative cells in the internal epithelium of the proventricle after bisection at L2, posterior regeneration. Arrowhead points to double-labelled cells (EdU-chased/BrdU-pulsed cells). en endodermal cells, ep epidermal cells. Dashed lines circumscribe the shape of the animals. Scale bars: 100 μm (ac), 200 μm (b)
