One New Zealand researcher said the breakthrough might even offer a new way for same-sex couples to reproduce their own healthy children. By deleting these imprinted genes from immature eggs, the researchers produced "bi-maternal" mice – that's mice with two mothers - in the past. Haploid ESCs containing only a male parent's DNA were modified to delete seven key imprinted regions. However, she noted the current work was carried out in mice and involved a number of genetic modifications in embryonic stem cells.
