TOP STORY
Derivation and Cardiomyocyte Differentiation of Induced Pluripotent Stem Cells from Heart Failure Patients
Scientists aimed to derive human-induced pluripotent stem cells (hiPSCs) from heart failure patients, to induce their cardiomyocyte differentiation, to characterize the generated hiPSC-derived cardiomyocytes, and to evaluate their ability to integrate with pre-existing cardiac tissue.

O-GlcNAc Regulates Pluripotency and Reprogramming by Directly Acting on Core Components of the Pluripotency Network
O-linked-N-acetylglucosamine (O-GlcNAc) has emerged as a critical regulator of diverse cellular processes, but its role in embryonic stem cells and pluripotency has not been investigated. Here researchers showed that O-GlcNAcylation directly regulates core components of the pluripotency network. [Cell Stem Cell] Abstract

Molecular Analysis of FMR1 Reactivation in Fragile-X Induced Pluripotent Stem Cells and Their Neuronal Derivatives
Investigators evaluated the reactivation of FMR1 in fragile-X-induced pluripotent stem cells and their differentiated neuronal derivatives by epigenetic modulating drugs. [J Mol Cell Biol]

Generation of Induced Pluripotent Stem Cells from Primary Chronic Myelogenous Leukemia Patient Samples
Researchers generated induced pluripotent stem cells (iPSCs) from imatinib-sensitive chronic myelogenous leukemia (CML) patient samples. Remarkably, the CML-iPSCs were resistant to imatinib although they consistently expressed BCR-ABL oncoprotein. [Blood] Abstract

Efficient Introduction of Specific TP53 Mutations into Mouse Embryonic Fibroblasts and Embryonic Stem Cells
Researchers described a rapid, precise method for generating sets of embryonic stem cells or mouse embryonic fibroblasts harboring point mutations in the p53 tumor suppressor gene. [Nat Protoc] Abstract

Generation of Induced Pluripotent Stem Cells from Human Renal Proximal Tubular Cells with Only Two Transcription Factors: OCT4 and SOX2
Investigators described the rapid, reproducible and highly efficient generation of induced pluripotent stem cells derived from endogenous kidney tubular renal epithelial cells with only two transcriptional factors: OCT4 and SOX2. [J Biol Chem] Full Article

Highly Sensitive In Vitro Methods for Detection of Residual Undifferentiated Cells in Retinal Pigment Epithelial Cells Derived from Human iPS Cells
The findings provide highly sensitive and quantitative in vitro assays essential for facilitating safety profiling of human induced pluripotent stem cell (hiPSC)-derived products for future regenerative medicine research. [PLoS One] Full Article

Mechanics Regulates Fate Decisions of Human Embryonic Stem Cells
Results highlighted the important functional link between matrix rigidity, cellular mechanics, and pluripotency of human embryonic stem cells (hESCs) and provided a novel approach to characterize and understand mechanotransduction and its involvement in hESC function. [PLoS One] Full Article

Three-Dimensional Growth Matrix for Human Embryonic Stem Cell-Derived Neuronal Cells
Researchers characterized the suitability of a 3D synthetic hydrogel matrix, PuraMatrix™, as a growth platform for human embryonic stem cell-derived neural cells. [J Tissue Eng Regen Med] Abstract
