“…Cryopreserved ovarian tissue, which was later auto-, allo-or xenografted, has been done in a variety of species including humans (Weissman et al, 1999;Gook et al, 2001;Gook et al, 2003;Donnez et al, 2004), non-human primates -rhesus macaque (Macaca mulatta) (Lee et al, 2004), cynomolgus macaque (Macaca fascicularis) (Schnorr et al, 2002) and common marmoset (Callytrix jacchus jacchus) (von Schönfeldt et al, 2011), bovine (Herrera et al, 2002), sheep (Gosden et al, 1994), cats (Gosden et al, 1994;Jewgenow et al, 1997;Bosch et al, 2004;Jewgenow & Paris, 2006;Luvoni, 2006), mice (Parrott, 1960;Liu et al, 2000;Liu et al, 2001), rabbits (Almodin et al, 2004), common wombat (Vombatus ursinus) (Wolvekamp et al, 2001;Cleary et al, 2003), African elephant (Loxodonta Africana) (Gunasena et al, 1998), Amur leopard (Panthera pardus orientalis) and African lion (Panthera leo) , tammar wallaby (Macropus eugenii) (Mattiske et al, 2002), and Fat-tailed dunnart (Sminthopsis crassicaudata) (Shaw et al, 1996). The last two are of special interest as they demonstrate that even when xenografting between species so philogentically distant as marsupials and mice, the graft is still supported and oocytes can develop.…”
