Graphical Abstract Highlights d Reversion or derivation of hESCs in 5iLAF results in SSEA4-negative cells d SSEA4-negative hESCs show gene expression consistent with naive pluripotency d Naive hESCs show lost ''memory'' of gamete and blastocyst methylation d Imprinting is lost in naive hESCs In Brief Pastor and colleagues show that reversion of primed hESCs in 5iLAF, or derivation of hESCs in 5...
Studies using animal models demonstrated the importance of autocrine/paracrine factors secreted by preimplantation embryos and reproductive tracts for embryonic development and implantation. Although in vitro fertilization-embryo transfer (IVF-ET) is an established procedure, there is no evidence that present culture conditions are optimal for human early embryonic development. In this study, k...
BACKGROUND Implantation is a complex initial step in the establishment of a successful pregnancy. Although embryo quality is an important determinant of implantation, temporally coordinated differentiation of endometrial cells to attain uterine receptivity and a synchronized dialog between maternal and embryonic tissues are crucial. The exact mechanism of implantation failure is still poorly un...
BACKGROUND TIA-1-related (TIAR) protein is a shuttling RNA-binding protein involved in several steps of RNA metabolism. While in the nucleus TIAR participates to alternative splicing events, in the cytoplasm TIAR acts as a translational repressor on specific transcripts such as those containing AU-Rich Elements (AREs). Due to its ability to assemble abortive pre-initiation complexes coalescing ...
