Same-sex in play

Shepparton News - - ENTERTAINMENT -

Is this the start of male ob­so­les­cence?

Re­searchers from China have bred healthy mice with two mums that went on to have nor­mal pups of their own by al­ter­ing stem cells from a fe­male mouse and in­ject­ing them into the eggs of an­other.

Of 210 em­bryos, 29 sur­vived.

Mice pups from two dads were also born us­ing a sim­i­lar but more com­plex ap­proach, but they only sur­vived for a cou­ple of days.

The re­searchers were ex­am­in­ing what makes it so chal­leng­ing for mam­mals of the same sex to re­pro­duce, and found that some of these bar­ri­ers can be over­come us­ing stem cells and tar­geted gene edit­ing.

The au­thors noted that there are still ob­sta­cles to us­ing these meth­ods in other mam­mals.
