From fish to cells: Establishment of continuous cell lines from embryos of annual killifish Nothobranchius furzeri and N. kadleci.

There is a growing need of alternative experimental models that avoid or minimize the use of animals due to ethical, economical, and scientific reasons. Surprisingly, the stable embryonic cell lines representing Nothobranchius spp., emerging vertebrate models in aging research, regenerative medicine, ecotoxicology, or genomics, have been not derived so far.
