Spore: for real this time.
Zebrafish development tracked cell by cell
Microscopic imaging reconstructs embryo's first day.
Fluorescence microscopy can reconstruct a digital zebrafish embryo.P. KELLER/EMBLA new type of microscope has allowed scientists to map the behaviour and movements of cells during zebrafish (Danio rerio) embryonic development, and create a three-dimensional digital movie of the process.
The team, from the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, says that this is the first complete developmental blueprint of a vertebrate. They think that the technique, called digital scanned laser light-sheet fluorescence microscopy (DSLM), could be applied to embryos of other vertebrates such as mice and frogs.
