First parthenogenetic mammal. Live parthenote mouse pups were produced from parthenogenic embryonic stem cells through tetraploid embryo complementation, which contributes to placenta development. This is the first demonstration that parthenogenetic embryonic stem cells are capable of tull-term development and can differentiate into all cell types and functional organs in the body.
