Glyoxalase I Disruption and External Carbonyl Stress Impair Mitochondrial Function in Human Induced Pluripotent Stem Cells and Derived Neurons
Scientists found that disruption of glyoxalase I , the gene encoding a major catabolic enzyme scavenging the carbonyl group, increased vulnerability to external carbonyl stress, leading to abnormal phenotypes in hiPSCs.

hERG-Deficient Human Embryonic Stem Cell-Derived Cardiomyocytes for Modelling QT Prolongation
The KCNH2 was knocked out in the hESC H9 line using the CRISPR/Cas9 system. Using a chemically defined differentiation protocol, investigators obtained and verified human ether-a-go-go-related gene(hERG)-deficient cardiomyocytes. Subsequently, high-throughput microelectrode array assays and drug interventions were performed to characterise the electrophysiological signatures of hERG-deficient cell lines.

Patient-Specific iPSC-Derived Cardiomyocytes Reveal Abnormal Regulation of FGF16 in a Familial Atrial Septal Defect
The authors generated a patient-specific iPSC line from a family cohort carrying a hereditary atrial septal defect (ASD) mutation in GATA4 gene, as well as a hESC line carrying the isogenic T280M mutation using the CRISPR/Cas9 genome editing method. The GATA4-mutant iPSCs and ESCs were then differentiated into cardiomyocytes to model GATA4 mutation-associated ASD.

The C-Mannosylome of Human Induced Pluripotent Stem Cells Implies a Role for ADAMTS16 C-Mannosylation in Eye Development
To interrogate the C-mannosylome of hiPSCs, researchers compared the secretomes of CRISPR-Cas9 mutants lacking either the C-mannosyltransferase DPY19L1 or DPY19L3 to wild-type hiPSCs using mass spectrometry-based quantitative proteomics.

Retinoic Acid Induces NELFA‐Mediated 2C‐like State of Mouse Embryonic Stem Cells Associates with Epigenetic Modifications and Metabolic Processes in Chemically Defined Media
Scientists showed that retinoic acid had a broader role in 2C‐like cells state, not only was one of the upstream regulators of the 2C‐like state in chemically defined media but also illuminated genetic and epigenetic regulations that govern ESCs to 2C‐like transition.

An Intronic Variant of CHD7 Identified in Autism Patients Interferes with Neuronal Differentiation and Development
To investigate whether the autism spectrum disorder-associated CHD7 intronic variant affects neural development, researchers established human embryonic stem cells carrying this variant using CRISPR/Cas9 methods and found that the level of CHD7 mRNA significantly decreased compared to control.

Phenotypic Recapitulation and Correction of Desmoglein-2-Deficient Cardiomyopathy using Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes
Scientists identified a homozygous stop-gain mutations in DSG2 that led to complete desmoglein-2 deficiency in a patient with severe biventricular heart failure. Induced pluripotent stem cells were generated from the patient, and the mutated DSG2 gene locus was heterozygously corrected to a normal allele via homology-directed repair.
