... overlapping but distinct expression profiles, with high NANOGP1 expression restricted to early epiblast cells and naïve-state pluripotent stem cells. Sequence analysis and epitope-tagging revealed that NANOGP1 is protein coding with an intact homeobox domain. The duplication that created NANOGP1 occurred...

...Anish Dattani; Tao Huang; Corin Liddle; Austin Smith; Ge Guo ABSTRACT Propagation of human naïve pluripotent stem cells (nPSCs) relies on the inhibition of MEK/ERK signalling. However, MEK/ERK inhibition also promotes differentiation into trophectoderm (TE). Therefore, robust self-renewal requires...

... and MYC (OSKM) enables reprogramming of differentiated cells into pluripotent embryonic stem cells. Methods based on partial and reversible in vivo reprogramming are a promising strategy for tissue regeneration and rejuvenation. However, little is known about the barriers that impair reprogramming...

... ABSTRACT Despite four decades of effort, robust propagation of pluripotent stem cells from livestock animals remains challenging. The requirements for self-renewal are unclear and the relationship of cultured stem cells to pluripotent cells resident in the embryo uncertain. Here, we avoided using feeder...

... and function, microtubules have received less attention when unravelling the regulatory circuitry of pluripotency. Here, we summarise the role of microtubule organisation and microtubule-dependent events required for the formation of pluripotent cells in vivo by deciphering the process of early embryogenesis...

...Nicola Festuccia; Nick Owens; Almira Chervova; Agnès Dubois; Pablo Navarro ABSTRACT The maintenance of pluripotency in mouse embryonic stem cells (ESCs) is governed by the action of an interconnected network of transcription factors. Among them, only Oct4 and Sox2 have been shown to be strictly...

Importantly, EpiLCs are considered equivalent to post-EPI cells in the E5.5 embryo, and are thought to represent a ‘formative state ’ of pluripotency ( Smith, 2017 ). In contrast, mouse ESCs cultured in 2i+LIF are equivalent to pre-EPI cells of the blastocyst...

Here, we consider the experimental potential of various ESC populations and a number of recently identified in vitro culture systems producing states beyond pluripotency and reminiscent of those observed during pre-implantation development. We also...

...Zhenhua Zhu; Yan Zhang; Xiaoxiao Wang; Xiaohu Wang; Shou-Dong Ye ABSTRACT The identification of novel mechanisms to maintain embryonic stem cell (ESC) pluripotency is of crucial importance, because the currently used culture conditions are not suitable for ESCs from all species.

Its differentiation starts at gastrulation, when...
