Fig. 4

(A) Representative images of centrosomes (γ-tubulin) in heart cryosections of adult transgenic cmlc2:dsRedExp-nuc^hsc4 zebrafish, of adult newt hearts, and adult mouse hearts. Nuclei: DAPI, cardiac nuclei: DsRed or Nkx2.5. Green-framed expansions: newt and zebrafish cardiomyocyte nuclei with paired-centrioles. Yellow-framed expansion: mouse non-myocyte nucleus with paired-centrioles. White asterisk: cardiomyocyte nucleus. Yellow scale bar: 10 �m. Red scale bar: 2 �m. (B) Quantitative analysis of nuclei associated with intact centrosomes in cryosections as shown in (A). Data are mean � SD, n = 3, e 300 cells were analyzed per experimental condition, *: p < 0.05. (C) Representative images documenting localization of microtubule regrowth (β-tubulin) in cultured adult zebrafish (Troponin I) and newt (phalloidin-TRITC) cardiomyocytes. Adult zebrafish were treated with serum (control), nocodazole, or nocodazole followed by wash out. Adult newt cardiomyocytes were treated with serum (control), ice, or ice followed by return to normal (norm) temperature. Nuclei: DAPI. Yellow arrowheads: localization of centrosome. Yellow scale bar: 10 �m.
