Mice blastocysts develop into embryos in orbital microgravity:

Skepticism is good, but ignoring related work weakens an argument.

This is a blastocyst, then back to earth experiment. No organ development?

Blastocyst to embryo. It's not in itself evidence that humans can grow in space. It's evidence that the early stages of mammal morphogenesis work fine. So why conclude without evidence that human morphogenesis probably won't? It's too early to say either way.
