Zebrafish heart regeneration is sexually dimorphic. (A) PCNA immunofluorescence (red) in the heart of untreated female, untreated male, 7 dpc female (c) and 7 dpc male. Scale bars: 100μm. (B) Quantification of percentage of PCNA-positive cells (mean ± s.d., n = 7) in panel A. (C) Vimentin immunofluorescence (red) in female and male Tg (cmlc2: eGFP, green) zebrafish hearts at 7 dpc. Scale bars: 100 μm. (D) Quantification of vimentin expression in the injured area of female and male zebrafish heart (marked by dashed lines, mean ± s.d., n = 8). (E) Picrosirus red staining of female and male zebrafish hearts at 1 dpc and 30 dpc. (F) Quantification of scar volume (marked by dashed lines, mean ± s.d., n = 9~12) between females and male zebrafish. Scale bars: 200 μm. Two-tail t test in figure B, D and F, **P < 0.01, n.s., not significant. Un, untreated; Dpc, days post-cryoinjury; CI, Cryoinjury.
