Testes regeneration in S. mediterranea hermaphrodites. (A) Expression pattern of a T-plastin homolog (DN311193) in intact and regenerating animals (n = 3 per stage). Days after amputation are indicated below each animal. (Scale bar, 1 mm.) (B) Expression pattern of Smed-nanos in intact (n = 2) and regenerating planarians (n = 4 per stage). (Scale bar, 1 mm.) (C) Confocal projections showing FISH to detect nanos mRNA in intact (n = 4) and regenerating planarians (n = 4 per stage). Arrows indicate the central portion of testes lobes. (Scale bar, 100 μm.)
