Until now, scientists have only succeeded in creating haploid embryonic stem cells -- which contain a single set of chromosomes -- in non-human mammals such as mice, rats and monkeys.

For example, recent haploid genetic screens in near-haploid human cells 6 have led to the identification of host factors used by pathogens 7. Haploid ES cells combine the advantages of haploidy ...

Until now, scientists have only succeeded in creating haploid embryonic stem cells — which contain a single set of chromosomes — in non-human mammals such as mice, rats and monkeys.

Mouse embryonic stem cells that contain half the usual number of chromosomes could be used to untangle gene pathways.
