Summary: YY2, a mammalian-specific transcription factor, is expressed during mouse preimplantation development but its presence seems to be dispensable until the blastocyst stage in vitro. Depletion of Yy2 in mESCs results in increased levels of Zscan4 expression but does not affect the expression of TEs or other pluripotency markers.

Summary: Stem cell differentiation is influenced by the interaction between cells and their extracellular matrix, with matrix metalloproteinases (MMPs) playing a role in this process. Differentiation of mouse embryonic stem cells (mESCs) on varying matrices led to changes in MMP expression and activity, affecting integrin expression, mechanotransduction pathways, and germ layer-specific markers. Inhibition of MMP activity altered the germ layer commitment of differentiating mESCs, demonstrating the importance of MMPs in regulating stem cell differentiation.

Summary: A simple method was developed to generate immature oligodendrocyte lineage cells from mouse ESC-derived neural stem cells, which showed potential for differentiation into mature OPC under specific conditions. Interestingly, these cells retained multipotentiality and could differentiate into neurons or astrocytes. However, their efficiency in myelinating axons was lower compared to primary OPC.

Summary: Deciphering the clues of a regenerative mechanism for the mammalian adult heart, particularly focusing on the role of DAND5, could potentially lead to the development of more effective treatment options for heart failure. Further research on the transcriptional profiling sequencing and quantitative RT-PCR assays of DAND5 may provide insights into the generation and expansion of pluripotent stem cell-derived cardiomyocytes systems for clinical applications.

Summary: This review article addresses the enigmatic role of the p53 transcription factor and tumor suppressor in programmed cell death during embryonic development. Contradictory results regarding the dependence of pluripotent embryonic stem cells on p53 for cell death are reconciled based on experimental conditions. The review concludes that p53 is not required for mouse embryonic development, but can accelerate programmed cell death in certain conditions. Additionally, DNA damage in differentiated cells induces p53-dependent cell cycle arrest and senescence.

Summary: Recent studies using single-cell RNA-sequencing have identified cellular heterogeneity in the developing mammalian cerebellum, but the regulatory logic behind this diversity remains unclear. Researchers integrated single-cell RNA and ATAC analyses to understand the developmental trajectories of cerebellar progenitors and identified potential regulatory elements controlling cell state transitions. Using gene regulatory network analysis, they uncovered the molecular control of a specific progenitor zone and demonstrated its association with a common cerebellar birth defect in humans.

Summary: The adult mammalian kidney lacks stem cells for regeneration, unlike the embryonic kidney which contains lineage-specific stem cells giving rise to various kidney components; current research focuses on these embryonic progenitor cells which can shed light on the formation of Wilms tumor, a pediatric renal cancer.

Summary: The study developed a stepwise strategy to generate chemically induced neural crest cells (ciNCCs) and chemically induced corneal endothelial cells (ciCECs) from mouse fibroblasts using defined small molecules. The resulting ciCECs exhibited consistent gene expression profiles and self-renewal capacity to primary CECs, and could be cultured for as long as 30 passages while retaining their features. Transplantation of these ciCECs into an animal model reversed corneal opacity, providing an alternative cell source for regeneration of corneal endothelia and tissues derived from neural crest.

Summary: This study found the presence of micro- and nanoplastics in human blood and placentas, indicating embryonic exposure to these particles. Furthermore, the exposure to polystyrene nanoplastics (PS-NPs) was found to negatively impact the cardiac differentiation of human embryonic stem cells (hESCs), leading to immature cardiomyocytes and impaired contractility. Mechanistically, PS-NPs induced mitochondrial oxidative stress, activated P38/Erk MAPK signaling pathway, and blocked autophagy flux, reducing the pluripotency of hESCs. Consistent results were observed in zebrafish embryo models, with reduced cardiac contraction and blood flow after exposure to PS-NPs.

Summary: This article investigates the genetic regulatory mechanisms of Drosophila intestinal stem cells. The study found that most target genes co-regulated by Esg and STAT show a consistent gene expression pattern. However, manipulating these validated targets in vivo rarely replicated the effects of manipulating Esg and STAT, suggesting the presence of complex genetic interactions among the downstream targets of these two master regulator genes.

Summary: Researchers found that conditional deletion of Robo2 in adult mice led to a significant loss of islet architecture without affecting beta cell identity or function, suggesting that Robo2 plays a role in actively maintaining adult islet architecture. Understanding the factors required for islet architecture maintenance is crucial for developing future diabetes therapies.

Summary: Knock-in reporter (KI) animals are essential for studying gene expression in biomedical research. This study developed a new strategy using minicircle technology and a minimal promoter to enhance knock-in events and establish stable KI transgenic reporter lines. The study also highlighted the importance of selecting the proper KI line due to potential inappropriate influence of genome editing on reporter gene expression.
