... to induced pluripotent stem (iPS) cells. Here, we show that LIN28 accumulates at the NPB and the mature nucleolus in mouse preimplantation embryos and embryonic stem cells (ESCs), where it colocalizes with the nucleolar marker B23 (nucleophosmin 1). LIN28 has nucleolar localization in non-human primate (NHP...

Reactivation of gene expression by DNA replication would therefore serve to coordinate cell proliferation and differentiation in the preimplantation embryo. * Author for correspondence (e-mail: jfnicola@pasteur.fr...

... complex detected in the mouse egg and zygote ( Howlett, 1986 ). Since this protein complex is so abundantly synthesized and migrates differentially in a cell-cycle-dependent manner during early embryo development, it has been repeatedly detected in numerous studies of oocyte and preimplantation embryo...

... of cdc25a and cdc25b expression in preimplantation embryos has also been carried out. These studies reveal that cdc25b transcripts are expressed in the one-cell embryo, decline at the two-cell stage and are re-expressed at the four-cell stage, following the switch from maternal to zygotic transcription...
