NICD overexpression leads to increased blastema width and increases EGFP expression in Tg(UAS:NICD);Et33-mi60A fish. (A,B) Immunohistochemistry for Myc does not label wild-type fin sections (A), whereas Myc-NICD expression is detected in peripheral cells, most likely osteoblasts, and cells within the ray in the fin stump of Tg(UAS:NICD) fish (B). (C) Mean blastema width of wild-type and Tg(UAS:NICD) fin sections at 5 dpa. ***P<0.05. (D-E′) Tg(UAS:NICD) fish were crossed with Et33-mi60A fish and the Tg(UAS:NICD);Tg Et33-mi60A fish were exposed to a series of heat shocks during 5 days of regeneration. EGFP expression is increased in Tg(UAS:NICD);ET33-mi60A fish at 5 dpa (E9) compared with ET33-mi60A fish. Scale bars: 10 μm. Broken lines mark the amputation plane.
