    A Spatially Resolved Timeline of the Human Maternal–Fetal Interface

    The authors used a multiomics approach, combining the strengths of spatial proteomics and transcriptomics, to construct a spatiotemporal atlas of the human maternal–fetal interface in the first half of pregnancy.

    Transplanting FVIII/ET3-Secreting Cells in Fetal Sheep Increases FVIII Levels Long-Term without Inducing Immunity or Toxicity

    Investigators showed that prenatal transplantation of human placental cells bioengineered to produce an optimized FVIII protein, resulting in considerable elevation in plasma FVIII levels that persisted for >three years post-treatment.

    The Human Placenta Exhibits a Unique Transcriptomic Void

    The human placenta exhibits a unique genomic architecture with an unexpectedly high mutation burden and many uniquely expressed genes. Researchers aimed to identify transcripts that were uniquely absent or depleted in the placenta.

    Umbilical Cord Mesenchymal Stem Cells Overexpressing CXCR7 Facilitate Treatment of ARDS-Associated Pulmonary Fibrosis via Inhibition of Notch/Jag1 Mediated by the Wnt/β-Catenin Pathway

    The authors examined whether overexpression of C-X-C chemokine receptor type 7 (CXCR7) in umbilical cord MSCs could improve their homing efficiency, and therefore, improve their effectiveness in fibrosis repair at the site of lung injury caused by acute respiratory distress syndrome.

    Ohwia caudata Aqueous Extract Attenuates Doxorubicin-Induced Mitochondrial Dysfunction in Wharton’s Jelly-Derived Mesenchymal Stem Cells

    Investigators focused on screening the senomorphic properties of Ohwia caudata aqueous extract as an emerging strategy for preventing or treating mitochondrial dysfunction in stem cells.

    Abstract

    Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Restored Hematopoiesis by Improving Radiation Induced Bone Marrow Niche Remodeling in Rats

    In comparison to the irradiated group, the irradiated+human umbilical cord blood derived-MSCs group showed restored cell populations and extracellular collagen components of the bone marrow niche with significant increase in hematopoietic stem, progenitor, mature and proliferating cells.

    Ambient Temperature, Heat Stress and Fetal Growth: A Review of Placenta-Mediated Mechanisms

    The authors first summarize evidence linking ambient temperature or experimentally-induced heat stress with fetal and placental growth outcomes in humans, ruminants, and murine species. They then synthesize the literature on putative underlying biological pathways with a focus on the placenta.

    Medicine Is Plagued by Untrustworthy Clinical Trials. How Many Studies Are Faked or Flawed?

    In October 2020, John Carlisle reported a startling estimate of the number of clinical-trial studies in medical journals that are fake or fatally flawed. For more than 150 trials, Carlisle got access to anonymized individual participant data and judged that 44% of the trials contained at least some flawed data.
