    A Congenital Hydrocephalus-Causing Mutation in Trim71 Induces Stem Cell Defects via Inhibiting Lsd1 mRNA Translation

    Using mESCs as a model, scientists revealed that the mouse R783H mutation, R796H in human, altered Trim71’s mRNA substrate specificity and led to accelerated stem-cell differentiation and neural lineage commitment.

    Antisense-Oligonucleotide-Mediated Perturbation of Long Non-Coding RNA Reveals Functional Features in Stem Cells and across Cell Types

    Within the scope of the FANTOM6 consortium, researchers performed a large-scale knockdown of 200 long non-coding RNAs in iPSCs and systematically characterized their roles in self-renewal and pluripotency.

    Antigen-Specific TCR-T Cells from Rag2 Gene-Deleted Pluripotent Stem Cells Impede Solid Tumor Growth in a Mouse Model

    To improve the homogeneity, antigen-specificity, and reduce possible autoreactivity, investigators developed a technique to generate antigen-specific T cells from Rag2 gene-deleted PSCs and further measured their anti-tumor efficacy.

    TPX2 Prompts Mitotic Survival via the Induction of BCL2L1 through YAP1 Protein Stabilization in Human Embryonic Stem Cells

    Researchers demonstrated that the expression of targeting protein for Xklp2 (TPX2) led to BCL2L1 induction and consequent survival traits under mitotic stress in isogenic pairs of hESCs and iPSCs with normal and 20q11.21 copy number variations.

    Investigating Neural Differentiation of Mouse P19 Embryonic Stem Cells in a Time-Dependent Manner by Bioinformatic, Microscopic, and Transcriptional Analyses

    By applying the in vitro differentiation of mouse pluripotent P19 cell line into neuron-like cells through retinoic acid treatment, the roles of some genes including DNMT3B, ICAM1, IRX3, JAK2, LHX1, SOX9, TBX3 , and THY1 in neural differentiation was investigated.
