Embryonic stem cells, cell transplantation and nuclear transplantation in fish.

Author(s) : HONG Y., SCHARTL M.

Summary

The genetic diversity of an increasing number of aquatic species is becoming threatened. Since long-term cryopreservation of whole embryos or ova is extremely difficult in fish, the authors propose a novel approach based on embryonic stem cells to preserve such genetical sources in the form of cell banks. Embryonic stem cells are embryo-derived, totipent cells. They can be easily maintained and stored. Like indeterminant embryonic cells they may participate in normal development and contribute to the germ line when reintroduced into host embryos. In the paper the authors review procedures and progress in embryonic stem cell cultivation, cell transplatation and nuclear transplantation in fish, and discuss prospects for their use in preservation of fish diversity.
