Early-stage sperm cells created from bone marrow My favourite bit is this:
And if female bone marrow is also able to produce sperm
cells, it raises the possibility that women would be able to pass on
their genetic material through manufactured sperm.
How cool is that?
Yeah, yeah, I know. This is crazy-theoretical and they don't even have
full-on sperm cells from the men yet. But I just love the idea.
