At launch, the embryos were only two cells, very early in their development, and were in a solution that fed the embryos the nutrients they needed to mature.

Science latest

The researchers outfitted the chamber with a camera that took photos of the embryos every four hours. From those photos, the researchers found that within four days, a number of the embryos developed into blastocysts, a more complex embryo that has some cell differentiation.

Studies using simulated microgravity on Earth showed birth rates due to poor placental development, indicating that microgravity has an adverse but unknown role in fertilization and gestation. Space Pup will help isolate radiation as a factor in long-term studies.

Earth Applications The gestational period is highly sensitive to environmental factors, including radiation and potentially the effects of gravity. Results from this experiment should provide valuable information for the collection and preservation of mammalian reproductive tissue for a range of uses. Please provide temperature data of On-orbit. Space Pup Sample Cases will be returned one by one at ambient. Preserved freeze-dry mouse spermatozoa were exposed to cosmic radiation on the ISS for 9 months and then brought back to Earth for in-vitro fertilization.

Mammal Embryos Have Been Grown In Space For The First Time

The overall morphology of space sperm did not differ from ground controls and DNA damage was only slightly increased. During fertilization, most oocytes female germ cells formed normal pronuclei similar to ground controls.

The offspring derived from space sperm and control sperm showed similar birth rates. After pups grew to adulthood, some pairs were mated with each other.
