Cardiomyocytes Recruit Monocytes upon SARS-CoV-2 Infection by Secreting CCL2

Both human pluripotent stem cell-derived cardiomyocytes and adult cardiomyocytes could be productively infected by SARS-CoV-2, leading to secretion of the monocyte chemoattractant cytokine CCL2 and subsequent monocyte recruitment.

Gene–Environment Interactions in Developmental Neurotoxicity: a Case Study of Synergy between Chlorpyrifos and CHD8 Knockout in Human BrainSpheres

The authors identified a potential synergy between mutation in the high-risk autism gene encoding chromodomain helicase DNA binding protein 8 and environmental exposure to an organophosphate pesticide an iPSC-derived human 3D brain model.

Deletion of RBMX RGG/RG Motif in Shashi-XLID Syndrome Leads to Aberrant p53 Activation and Neuronal Differentiation Defects

Scientists investigated the contribution of the X-linked intellectual disability (XLID)-associated RBMX in neuronal differentiation.Transcriptomic analysis of isogenic Shashi-XLID human iPSCs generated using CRISPR-Cas9 revealed a dysregulation of MDM4 splicing and aberrant p53 upregulation.

Prednisolone Rescues Duchenne Muscular Dystrophy Phenotypes in Human Pluripotent Stem Cell–Derived Skeletal Muscle In Vitro

Researchers described an optimized protocol to differentiate human iPSCs to a late myogenic stage, allowing them to recapitulate classical Duchenne muscular dystrophy (DMD) phenotypes in isogenic DMD-mutant iPSC lines in vitro.
