Platelet Lysate–Enriched Human Induced Pluripotent Stem Cell–Derived Chondrocyte Sheets for Bone Defect Repair via Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.

Higher O-GlcNAc Levels Are Associated with Defects in Progenitor Proliferation and Premature Neuronal Differentiation during in-Vitro Human Embryonic Cortical Neurogenesis

Frontiers in Cellular Neuroscience, 2017
The nutrient responsive O-GlcNAcylation is a dynamic post-translational protein modification found on several nucleocytoplasmic proteins. Previous studies have suggested that hyperglycemia induces the levels of total O-GlcNAcylation inside the cells ...

GENERATION OF MOUSE INDUCED PLURIPOTENT STEM CELLS BY PROTEIN TRANSDUCTION. [PDF]

, 2013
Somatic cell reprogramming has generated enormous interest after the first report by Yamanaka and his coworkers in 2006 on the generation of induced pluripotent stem cells (iPSCs) from mouse fibroblasts. Here we report the generation of stable iPSCs from

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

Advanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Dynamic Modulation of the Microenvironment Promotes Functional Maturation of Engineered Tissues

Advanced Healthcare Materials, EarlyView.
Engineered tissues lack the dynamic microenvironment of native tissues. A biocompatible, diffusible small molecule to dynamically modulate tissue microenvironments during maturation is used. Timing‐dependent modulation yields distinct outcomes, producing thicker, more native‐like blood vessels, stronger and more mature cardiac tissues, and optimized ...

TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

eLife, 2019
The mechanisms that regulate pluripotency are still largely unknown. Here, we show that Telomere Repeat Binding Factor 1 (TRF1), a component of the shelterin complex, regulates the genome-wide binding of polycomb and polycomb H3K27me3 repressive marks to

Proteomics and pluripotency [PDF]

Critical Reviews in Biochemistry and Molecular Biology, 2011
The fields of mass spectrometry (MS) and stem cell biology have expanded greatly in the past twenty years. Taken alone, these fields occupy entirely different branches of science; however, the points where they overlap provide valuable insight, both in the biological and technical arenas.

Recent Advances in Understanding the Reversal of Gene Silencing During X Chromosome Reactivation

Frontiers in Cell and Developmental Biology, 2019
Dosage compensation between XX female and XY male cells is achieved by a process known as X chromosome inactivation (XCI) in mammals. XCI is initiated early during development in female cells and is subsequently stably maintained in most somatic cells ...

Splicing up Pluripotency [PDF]

Cell, 2011
In this issue of Cell, Gabut and colleagues (2011) identify a new splice variant of FOXP1 that directly regulates the expression of pluripotency genes. It endows human embryonic stem cells with their pluripotent nature and is required for the reprogramming of somatic cells to induced pluripotent stem cells.
