Hallmarks of totipotent and pluripotent stem cell states
Cell Stem Cell. 2024 Feb 13:S1934-5909(24)00039-0. doi: 10.1016/j.stem.2024.01.009. Online ahead of print.ABSTRACTThough totipotency and pluripotency are transient during early embryogenesis, they establish the foundation for the development of all mammals. Studying these in vivo has been challenging due to limited access and ethical constraints, particularly in humans. Recent progress has led to diverse culture adaptations of epiblast cells in vitro in the form of totipotent and pluripotent stem cells, which not only deepen our understanding of embryonic development but also serve as invaluable resources for animal reprod...

Thalamocortical organoids enable in  vitro modeling of 22q11.2 microdeletion associated with neuropsychiatric disorders
Cell Stem Cell. 2024 Feb 13:S1934-5909(24)00040-7. doi: 10.1016/j.stem.2024.01.010. Online ahead of print.ABSTRACTThalamic dysfunction has been implicated in multiple psychiatric disorders. We sought to study the mechanisms by which abnormalities emerge in the context of the 22q11.2 microdeletion, which confers significant genetic risk for psychiatric disorders. We investigated early stages of human thalamus development using human pluripotent stem cell-derived organoids and show that the 22q11.2 microdeletion underlies widespread transcriptional dysregulation associated with psychiatric disorders in thalamic neurons and g...

Online ahead of print.ABSTRACTAdvances in hiPSC isolation and reprogramming and hPSC-CM differentiation have prompted their therapeutic application and utilization for evaluating potential cardiovascular safety liabilities. In this perspective, we showcase key efforts toward the large-scale production of hiPSC-CMs, implementation of hiPSC-CMs in industry settings, and recent clinical applications of this technology. The key observations are a need for traceable gender and ethnically diverse hiPSC lines, approaches to reduce cost of scale-up...

Canonical Wnt signaling directs the generation of functional human PSC-derived atrioventricular canal cardiomyocytes in bioprinted cardiac tissues
Cell Stem Cell. 2024 Feb 10:S1934-5909(24)00038-9. doi: 10.1016/j.stem.2024.01.008. Online ahead of print.ABSTRACTThe creation of a functional 3D bioprinted human heart remains challenging, largely due to the lack of some crucial cardiac cell types, including the atrioventricular canal (AVC) cardiomyocytes, which are essential to slow down the electrical impulse between the atrium and ventricle. By utilizing single-cell RNA sequencing analysis and a 3D bioprinting technology, we discover that stage-specific activation of canonical Wnt signaling creates functional AVC cardiomyocytes derived from human pluripotent stem cells...

Hypoimmune islets achieve insulin independence after allogeneic transplantation in a fully immunocompetent non-human primate
We report that allogeneic transplantation of genetically engineered (B2M-/-, CIITA-/-, CD47+), primary, hypoimmune, pseudo-islets (p-islets) results in their engraftment into a fully immunocompetent, diabetic non-human primate wherein they provide stable endocrine function and enable insulin independence without inducing any detectable immune response in the absence of immunosuppression. Hypoimmune primary p-islets may provide a curative cell therapy for type 1 diabetes mellitus.PMID:38335966 | DOI:10.1016/j.stem.2024.02.001 (Source: Cell Stem Cell)

Unraveling the brain's response to COVID-19: How SARS-CoV-2 afflicts dopaminergic neurons
Cell Stem Cell. 2024 Feb 1;31(2):152-154. doi: 10.1016/j.stem.2024.01.002.ABSTRACTCOVID-19 patients often display dysfunctions of the nervous system, indicating an effect of SARS-CoV-2 on neural cells.
