抄録

In the present study, embryo transfer was performed using frozen-thawed embryos to establish a SPF colony of human apolipoprotein (a) (apo(a)) transgenic rabbits. Apo(a) transgenic rabbits were kept under conventional condition and were infected with Bordetella bronchiseptica. Embryos at the morula stage were collected and stored in liquid nitrogen. After thawing, the in vitro survival rate was 84.6%, and 125 morphologically normal embryos were transferred to 6 SPF recipient rabbits. Four rabbits became pregnant and 23 live pups were born. PCR and Western blot analyses revealed that 9 of 23 pups were transgenic and expressed apo(a) protein. Microbiological tests showed all rabbits were free from infections. We succeeded in establishing a SPF colony of apo(a) transgenic rabbits. These rabbits are now maintained under a barrier system and are available for medical research.<br>
