A sperm bank to recreate animals on other planets

Japanese scientists have launched a sperm bank for endangered animals that uses freeze-drying technology they hope could one day help humans recreate animal populations on other planets, the chief researcher said. The team at Kyoto University’s Institute of Laboratory Animals Graduate School of Medicine successfully preserved sperm taken from two endangered primates and a type of giraffe, associate professor Takehito Kaneko said.

They mixed the sperm with special preservation liquid and freeze-dried it in a way that allows them to store it at just 4 degree Celsius, Kaneko said. The temperature much higher than conventional ways of storing sperm. Kaneko and his team have previously successfully freeze-dried sperm from rats and mice without the use of bulky liquid nitrogen equipment, and were able to prove the viability of the spermatozoa up to five years later.

“In this way, the scientists will be able to obtain genetic information more easily, which means we could help to preserve endangered animal species,” Kaneko said. Kaneko is quick to point out that there is presently no human application for the technology, but adds it is an avenue that may be explored in the future. “This may sound like a dream, but we could in the future take genetic information into space,” he said, adding it may allow for the transfer of material to help establish animal populations on future colonies.
