    Direct Neuronal Reprogramming of NDUFS4 Patient Cells Identifies the Unfolded Protein Response as a Novel General Reprogramming Hurdle

    The authors explored the effects of mitochondrial dysfunction on the neuronal reprogramming of iPSC-derived astrocytes carrying mutations in the NDUFS4 gene, important for Complex I and associated with Leigh syndrome.

    Induced Pluripotent Stem Cell–Derived Exosomes Attenuate Vascular Remodeling in Pulmonary Arterial Hypertension by Targeting HIF-1α and Runx2

    Investigators used murine iPSCs generated from mouse embryonic fibroblasts with triple factor transduction to determine the efficacy and action mechanism of iPSC-derived exosomes in attenuating pulmonary arterial hypertension.

    Tumor Suppressor Let-7 Acts as a Key Regulator for Pluripotency Gene Expression in Muse Cells

    In Muse cells, researchers demonstrated that let-7 inhibited the PI3K-AKT pathway, leading to sustainable expression of the key pluripotency regulator KLF4 as well as its downstream genes, POU5F1, SOX2, and NANOG.

    Enhanced Innate Responses in Microglia Derived from Retinoblastoma Patient-Specific iPSCs

    Microglia were successfully differentiated from retinoblastoma patient-derived human iPSCs and hESCs, and researchers investigated the function of RB1 in microglia by live imaging phagocytosis assay, immunofluorescence, RNA-seq, qRT-PCR, ELISA, and retina organoids/microglia co-culturing.

    Abstract

    Simulated Microgravity Improves Maturation of Cardiomyocytes Derived from Human Induced Pluripotent Stem Cells

    Following culture under simulated microgravity in a random positioning machine for seven days, 3D hiPSC-cardiomyocytes had increased mitochondrial content as detected by a mitochondrial protein and mitochondrial DNA to nuclear DNA ratio.

    Integration-Free Induced Pluripotent Stem Cells from Three Endangered Southeast Asian Non-Human Primate Species

    Scientists described the first successful integration-free reprogramming of adult somatic cells to iPSCs, and their differentiation, from three endangered Southeast Asian primates: the Celebes Crested Macaque, the Lar Gibbon, and the Siamang.

    Efficient Induction of Pluripotent Stem Cells Differentiated into Mesenchymal Stem Cell Lineages

    Scientists employed a comprehensive methodology involving the differentiation of iPSCs into mesenchymal stem cells (MSCs). The process was meticulously designed to ensure the expression of key MSC positive markers at elevated levels, coupled with the minimal expression of negative markers.

    Abstract

    Interleukin-22 (IL-22) Enhanced the Mucosal Barrier and Inhibited the Invasion of Salmonella enterica in Human Induced Pluripotent Stem Cell-Derived Small Intestinal Epithelial Cells

    Using microarray and Gene Set Enrichment Analysis, scientists found that hiPSC-small intestinal epithelial cell monolayers activated the immune response and enhanced the mucosal barrier in response to IL-22.

    Abstract

    Generation and Characterization of Two Vervet Monkey Induced Pluripotent Stem Cell Lines Derived from Fibroblasts

    The Vervet monkey serves as an important primate model for such studies, and therefore researchers reprogrammed skin fibroblasts derived from a male and a female individual, resulting in two iPSCs.
