The
T-Box Transcription Factor Eomesodermin Governs Hemogenic Competence of Yolk Sac Mesodermal Progenitors

Scientists demonstrated using an ESC model that transient expression of the T-box transcription factor Eomesodermin governs haemogenic competency of extra-embryonic mesoderm.

Abstract

Loss
of the Fragile X Syndrome Protein FMRP Results in Misregulation of Nonsense-Mediated mRNA Decay

The authors report that FMRP deficiency resulted in hyperactivated nonsense-mediated mRNA decay in human SH-SY5Y neuroblastoma cells and fragile X syndrome fibroblast-derived iPSCs.
[Nature Cell Biology]

Abstract

An Autophagy Enhancer Ameliorates Diabetes of Human IAPP-Transgenic
Mice through Clearance of Amyloidogenic Oligomer

Researchers showed that a recently identified autophagy enhancer (MSL-7) reduced human IAPP oligomer accumulation in human iPSC-derived β-cells and diminished oligomer-mediated apoptosis of β-cells.

Induced
Organoids Derived from Patients with Ulcerative Colitis Recapitulate Colitic Reactivity

Investigators took advantage of iPSCs to develop an induced human ulcerative colitis-derived organoid model and compared it with the induced human normal organoid model.

Stem-Cell-Derived
Human Microglia Transplanted into Mouse Brain to Study Human Disease

Scientists detailed an accurate, step-by-step workflow that includes in vitro microglia differentiation from human PSCs, transplantation into the mouse brain and quantitative analysis of engraftment.

Abstract

Engineering Human Hepato-Biliary-Pancreatic Organoids from Pluripotent Stem Cells

Investigators describe a protocol for the continuous patterning of hepatic, biliary and pancreatic structures from a 3D culture of human PSCs.

Abstract

Familial Alzheimer’s Disease Mutations in PSEN1
Lead to Premature Human Stem Cell Neurogenesis

Expression data from developmental and adult neurogenesis showed relative enrichment of Notch and γ-secretase expression in stem cells, whereas expression of APP and β-secretase was enriched in neurons.

A Genetic Screen Identifies Etl4-Deficiency
Capable of Stabilizing the Haploidy in Embryonic Stem Cells

The authors report a genome-wide loss-of-function screening that identified gene mutations that could significantly reduce the rate of self-diploidization in haploid ESCs.

Culture
Surface Protein Coatings Affect the Barrier Properties and Calcium Signaling of hESC-RPE

Investigators identified the role of retinal pigment epithelium (RPE) basement membrane proteins type IV collagen, laminin, and nidogen-1 in the maturation and functionality of human ESC-RPE after cryopreservation.

REVIEWS

Mitochondrial DNA Dynamics in Reprogramming to Pluripotency

The authors examine potential mechanisms for maintenance or shifts in heteroplasmy that occur in iPSCs generated by cellular reprogramming, and further discuss manipulations that can alter heteroplasmy to impact stem and differentiated cell performance.

The
Path to Progress Preclinical Studies of Age-Related Neurodegenerative Diseases: A Perspective on Rodent and hiPSC-Derived Models

Scientists advocate for a paradigm shift towards the application of human iPSC-derived systems for Alzheimer’s and Parkinson’s disease modeling and the development of improved human-based models in a dish for drug discovery and preclinical assessment of therapeutic targets.
