Male pectoral fin BT regeneration. Mallory stain of intact (A) and regenerating (B-F) pectoral fin longitudinal sections. (A,B) Keratinized caps (red) and underlying epidermis (blue) are observed on intact fins (A) but are lost in 3-dpa regenerates (B). (C,D) At 4-5 dpa, a layer of keratin is deposited in the proximal regenerate (black arrows). (E) At 7 dpa, BTs (black arrow) are observed in the fin regenerate. (F) Females do not possess BTs. Yellow arrows indicate blood cells. Black lines (B-F) indicate the amputation plane. dpa, days post-amputation. hr, hemiray. Scale bar: 50 μm. |
