Abstract Experimental animal models have played an indispensable role in the development of human induced pluripotent stem cell (iPSC) research. The derivation high-quality (so-called “true naïve state”) iPSCs non-human primates enhances their application and safety for regenerative medicine. Although several attempts been made to convert primate PSCs into a truly state, it is unclear which evaluation methods can discriminate them as being naïve. Here we attempted derive cynomolgus monkey (Cm) ( Macaca fascicularis ) embryonic cells (ESCs) iPSCs. Several characteristics Cm ESCs including colony morphology, appearance naïve-related mRNAs proteins, leukaemia inhibitory factor dependency, mitochondrial respiration were confirmed. Next, generated converted state. Transcriptomic comparison with early embryos elucidated partial achievement (termed naïve-like) conversion. When these subjected vitro neural differentiation, enhanced differentiating capacities observed after naïve-like conversion, but some lines exhibited heterogeneity. difficulty achieving contribution chimeric mouse was also demonstrated. These results suggest that could ameliorate differentiation potential even though they not display true characteristics.

Abstract High-resolution molecular programmes delineating the cellular foundations of mammalian embryogenesis have emerged recently. Similar analysis human embryos is limited to pre-implantation stages, since early post-implantation are largely inaccessible.

Abstract The International Stem Cell Initiative compared several commonly used approaches to assess human pluripotent stem cells (PSC). PluriTest predicts pluripotency through bioinformatic analysis of the transcriptomes undifferentiated cells, whereas, embryoid body (EB) formation in vitro and teratoma vivo provide direct tests differentiation. Here we report that EB assays, analyzed after differentiation under neutral conditions promoting ectoderm, mesoderm, or endoderm lineages, are sufficient potential PSCs. However, by histologic examination TeratoScore, which estimates differential gene expression each tumor, not only measures but also allows insight into a PSC’s malignant potential. Each assays can be predict but, at this stage assay development, provides an assessment potential, both relevant pre-clinical safety

Too many choices can be problematic. This is certainly the case for human pluripotent stem cells (hPSCs): they harbor potential to differentiate into hundreds of cell types; yet it highly challenging exclusively hPSCs a single desired type. review focuses on unresolved and fundamental questions regarding hPSC differentiation critiquing identity purity resultant populations. These are timely issues in view fact that hPSC-derived populations have or being transplanted patients over 30 ongoing clinical trials. While vitro protocols purport "mimic development," exact number intermediate steps takes given type vivo remains largely unknown. Consequently, most efforts inevitably generate heterogeneous cellular population, as revealed by single-cell RNA-sequencing other analyses. The presence unwanted types differentiated does not portend well transplantation therapies. provides an impetus precisely control ends-for instance, logically blocking formation overexpressing lineage-specifying transcription factors-or harnessing technologies selectively purify types.

Human pluripotent stem cells (hPSCs) exhibit very limited contribution to interspecies chimeras. One explanation is that the conventional hPSCs are in a primed state and so unable form chimeras pre-implantation embryos. Here, we show undergo rapid apoptosis when injected into mouse While, forced-expression of BMI1, polycomb factor overcomes enables integrate embryos subsequently contribute with both embryonic extra-embryonic tissues.
