Scientists claim to have created human sperm in laboratory

Are adult stem cells equivalent to embryonal ones?

From how I understood it, they just separated germline cells from very early embryos and let them develop into sperm in an incubator (that is, these germline stem cells would anyway develop into sperm, if left in the embryo).

While this is certainly interesting, for "curing" infertility, wouldn't you still need to find a way how to turn adult stem cells into germline stem cells?

This seems like equivalent problem to "growing hearts in a vat".

Amazing. This is actually much more interesting than the original post.

However soup of sperms has less structure than a heart. So it might be easier to grow.
