    Generation of PARP1 Gene Knockout Human Embryonic Stem Cell Line Using CRISPR/Cas9

    To clarify the function of PARP1 in hESCs, scientists report a PARP1 knockout hESC line, generated by CRISPR/Cas9 mediated gene targeting. This cell line showed normal karyotype, pluripotent stem cell marker expression and differentiation potential in vitro.

    Abstract

    Efficient Induction of Neural Progenitor Cells from Human ESC/iPSCs on Type I Collagen

    The authors established a novel and robust monolayer differentiation method to produce functional neural progenitor cells (NPC) from hESC/iPSCs on Type I Collagen. The derived cells not only displayed the requisite markers, but also behaved similarly to classic NPCs both in vitro and in vivo.

    Abstract

    Long QT Syndrome 2 PAS Domain Variant Induces hERG1a/1b Subunit Imbalance in Patient-Specific iPSC-Cardiomyocytes

    hiPSCs were derived from a long QT syndrome type 2 (LQT2) patient carrying the Per-Arnt-Sim (PAS) domain variant hERG1-H70R. CRISPR/Cas9 gene editing produced isogenic control iPSC lines. Differentiated iPSC-derived cardiomyocytes were evaluated for their electrophysiology, hERG1a/1b mRNA expression, and hERG1a/1b protein expression.

    Abstract

    Heparin-Modified Alginate Microspheres Enhance Neovessel Formation in hiPSC-Derived Endothelial Cells and Heterocellular In Vitro Models by Controlled Release of Vascular Endothelial Growth Factor

    Investigators developed a biomimetic approach to increase the binding affinity of the extracellular matrix for the class of heparin‐binding growth factors to localize and control the release of proangiogenic cues while maintaining their bioactivity.
