品系来源：In 1989 RCC Ltd. of Switzerland obtained 156 breeding pairs of Wistar Hannovers from Dr. Willy Heine, Zentralinstitut f?r Versuchstierzucht (ZfV), Hannover, Germany. The stock was hysterectomy derived at RCC in 1989. Genetic drift in RCC?s colony of Wistar Hannovers is minimized through the use of the Poiley rotational breeding system and revitalization of the stock with cryopreserved embryos (most recent revitalization completed in 1998).Each Member of GALAS obtained in excess of fifty (50) Wistar Hannover breeders from RCC in late 1998. The line was cesarean derived in 1999 and Taconic replaced its former WH stock with the GALAS Wistar Hannover rat in June 2000.
