Genetic Insulin Resistance Is a Potent Regulator of Gene Expression and Proliferation in Human iPS Cells
To define the consequences of genetic insulin resistance distinct from those secondary to cellular differentiation or in vivo regulation, researchers generated induced pluripotent stem cells (iPSC) from individuals with insulin receptor mutations and age-appropriate controls, and studied insulin signaling and gene expression in comparison to fibroblasts from which they were derived.

Hepatic Differentiation of Human Embryonic Stem Cells as Microscaled Multilayered Colonies Leading to Enhanced Homogeneity and Maturation
Off-the-shelf micro-stencil arrays were developed to generate adherent multilayered colonies composed of human embryonic stem cell-derived cells. Compared with conventional 2D format, the micro-scaled multilayered colonies with uniform and defined sizes constrained within the microwells are composed of more homogenous and mature hepatocyte-like cells with significantly lowered AFP expression and elevated hepatic functions. [Small] Abstract

Mutation Frequency Dynamics in HPRT Locus in Culture-Adapted Human Embryonic Stem Cells and Induced Pluripotent Stem Cells Correspond to Their Differentiated Counterparts
Base excision repair (BER), a major genomic integrity maintenance mechanism, has been shown to fail during human embryonic stem cells (hESCs) adaptation. Investigators show that the increase in the mutation frequency caused by the inhibition of BER was similar to that caused by the hESC adaptation process. [Stem Cells Dev] Abstract

Incorporation of Gold-Coated Microspheres into Embryoid Body of Human Embryonic Stem Cells for Cardiomyogenic Differentiation
Investigators show that incorporation of gold-coated microspheres into human embryonic stem cell-derived embryoid bodies enhances the cardiomyogenic differentiation process of pluripotent embryonic stem cells. [Tissue Eng Part A] Abstract

Alginate Encapsulation of Human Embryonic Stem Cells to Enhance Directed Differentiation to Pancreatic Islet-Like Cells
Scientists developed a stage-wise directed differentiation protocol to produce alginate-encapsulated islet-like cells derived from human embryonic stem cells, which can be directly implanted for diabetes therapy. [Tissue Eng Part A] Abstract

Transplantation of Induced Pluripotent Stem Cells Improves Functional Recovery in Huntington’s Disease Rat Model
Researchers determined the functional recovery of transplanted induced pluripotent stem cells in a rat model of Huntington’s disease with use of 18F-FDG microPET/CT imaging. [PLoS One] Full Article

Modulating Notochordal Differentiation of Human Induced Pluripotent Stem Cells Using Natural Nucleus Pulposus Tissue Matrix
Scientists show that direct contact between human induced pluripotent stem cells and nucleus pulposus matrix can promote the differentiation yield, whilst both the contact and non-contact cultures can generate functional notochordal cell-like cells. [PLoS One] Full Article

Differentiation of Human Limbal-Derived Induced Pluripotent Stem Cells into Limbal-Like Epithelium
Researchers generated human induced pluripotent stem cells and directed them to limbal differentiation by maintaining them on natural substrata mimicking the native limbal epithelial stem cell niche, including feederless denuded human amniotic membrane and de-epithelialized corneas.
