RESUMO
Both embryo-derived (ESC) and induced pluripotent stem cell (iPSC) lines have been established in rabbit. They exhibit the essential characteristics of primed pluripotency. In this review, we described their characteristic features at both molecular and functional levels. We also described the attempts to reprogram rabbit pluripotent stem cells (rbPSCs) toward the naive state of pluripotency using methods established previously to capture this state in rodents and primates. In the last section, we described and discussed our current knowledge of rabbit embryo development pertaining to the mechanisms of early lineage segregation. We argued that the molecular signature of naive-state pluripotency differs between mice and rabbits. We finally discussed some of the key issues to be addressed for capturing the naive state in rbPSCs, including the generation of embryo/PSC chimeras.
