Generation of Medaka Fish Haploid Embryonic Stem Cells

Haploid Medaka Stem Cells
Although diploid embryonic stem cells have been generated by various means, there would also be value in deriving haploid stem cells. In these cells, recessive mutations in essential genes would show phenotypes that would not be apparent in heterozygous animals.

(p.

) used the medaka fish model system to generate haploid stem cells that show stable growth and pluripotency. In addition, a fertile female medaka fish was produced by haploid embryonic stem cell nuclear transfer into a normal egg. This system has potential for analyzing recessive genes, for example, in disease phenotypes or in various cell lineages in culture.
