    Trophoblast Stem Cell-Based Organoid Models of the Human Placental Barrier

    Researchers described the generation of trophoblast organoids using human trophoblast stem (TS) cells. Following treatment with three kinds of culture medium, TS cells form spherical organoids with a single outer layer of syncytiotrophoblast cells that displayed a barrier function.

    Epigenetic Drug Screening for Trophoblast Syncytialization Reveals a Novel Role for MLL1 in Regulating Fetoplacental Growth

    Scientists conducted a systematic drug screen using an epigenetic compound library to systematically investigate the epigenetic mechanism essential for syncytialization, and identified mixed lineage leukemia 1 (MLL1), a histone 3 lysine 4 methyltransferase, as a crucial regulator of trophoblast syncytialization.

    Cord Blood Derived-Multipotent Stem Cells Ameliorate In Vitro/In Vivo Alloreactive Responses and This Effect Is Associated with Exosomal Microvesicles In Vitro

    The authors explored the potential application of human cord blood derived-multipotent stem cells to control donor alloreactive responses involved in allogeneic hematopoietic cell transplantation, which often results in acute graft-vs-host disease.

    Exosomes Derived from Human Umbilical Cord Mesenchymal Stem Cells Pretreated by Monosialoteterahexosyl Ganglioside Alleviate Intracerebral Hemorrhage by Down-Regulating Autophagy

    In vitro, human umbilical cord MSCs were cultured and induced to differentiate into neuron-like cells after they were pretreated with 150 μg/mL monosialoteterahexosyl ganglioside.

    Abstract

    Human Umbilical Cord Mesenchymal Stem Cells Attenuate Diet-Induced Obesity and NASH-Related Fibrosis in Mice

    Investigators evaluated the therapeutic efficacy of human umbilical cord-MSCs in C57BL/6 mice with diet-induced non-alcoholic steatohepatitis (NASH). At week 32, mice were randomized into two groups: phosphate-buffered saline and MSCs, which were injected into the tail vein.
