Zebrafish (Danio rerio) is a small tropical freshwater fish that takes its name from the horizontal, blue-pigmented stripes aligning its body, which are reminiscent of the zebra stripes. Thanks to its various peculiarities, this fish is considered an excellent model organism compared to other species used in the laboratory. Who can imagine that it has about 70% similarity to the human genome and can reproduce human diseases? Furthermore, its regenerative capacity constitutes an interesting object of study for human regenerative medicine (neurodegenerative diseases, organ regeneration).
