Its donor cell came from the skin samples of a wild arctic wolf named Maya, who had been introduced from Canada to Harbin Polarland. Its oocyte was from a female dog in estrus and its surrogate mother was a beagle.

Now the wolf pup is in good health condition and lives with its surrogate mother at Harbin Polarland.
