Japanese scientists say mammalian embryos develop normally in space

A group of Japanese scientists states they have actually located that mammalian embryos develop normally in space under microgravity problems.

The scientists, consisting of Professor Wakayama Teruhiko of Yamanashi University and a group from the Japanese space firm JAXA, performed an experiment on the International Space Station.

They sent out icy computer mouse embryos aboard a rocket heading to the ISS in August 2021.

After the embryos were defrosted and cultured by astronauts for 4 days, they checked out whether the embryos became blastocysts. A blastocyst includes cells that develop right into the unborn child and the placenta.

The scientists located that 17 of 72 embryos, or 23.6 percent, became blastocysts under microgravity, while 19 of 61 embryos, or 31.1 percent, became blastocysts under …
