Understanding on the patterning and morphogenesis of embryo and organ development has become a subject of enormous scientific and clinical interest. Zebrafish, which have small, accessible, transparent embryos and larvae, provides a unique living animal model to facilitating high-resolution imaging on embryos and developing organ. Numerous transgenic zebrafish lines have been generated with endogenous fluorescent labeling of developing heart. These animals facilitate high-resolution imaging of individual cardiac cell in vivo and make possible long-term time-lapse imaging of the dynamics of cardiac patterning and morphogenesis. We quantify cardiac cell number using confocal microscopy analysis in Tg(cmlc2:EGFP-nuc) embryos in which a gene encoding fluorescent protein is expressed in nuclei under the control of the cmlc2 promoter. These features make zebrafish particularly well suited for discovering small-molecule regulators of cardiac cell production and regeneration. However, computation algorithms are required to develop to facilitate the automation of cardiac cell number quantification. This may ultimately aid in design of therapeutic approaches for heart regeneration and repair.

Brainbow, a new imaging technology, was recently developed that allowed the designation of 90 colour labels to zebrafish developing heart. With this technology, it was possible to visualize adjacent cardiomyocyte and their connections in the heart with high resolution. The ability to assign many colours to different cardiomyocyte in a population can be applied to investigating cardiomyocyte proliferation, lineage decisions, cardiac patterning and morphogenensis. The large amounts of 3-dimensional imaging data are recognized and analyzed by advanced computation methods.
