Popis: | The flight procedure of “Experience Triton” on Cosmos 2229 made necessary to sacrifice the embarked females just after landing. In order to detect genetic abnormalities in the progeny of these adult females, we have performed a surgical procedure based on the transplantation of an ovarian piece on a recipient animal. One year later, as observed after laparotomy, the grafted ovaries exhibit oogonies and some growing oocytes. In present time, out of 10 castrated and grafted adult females only one is still alive bearing a large grafted ovary. Out of 5 castred and grafted juvenile males, three are still alive, two of them exhibit a developping grafted ovary. The grafted animals will be ready for mating within a few months. Therefore, it will soon be possible to study the progeny of animals that have been submitted to space conditions. |
