​STEMdiff™ Neural Rosette Selection Reagent is an enzyme-free reagent for the selective detachment of neural rosette clusters from adherent neural aggregates previously generated from human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells using STEMdiff™ Neural Induction Medium, without manual scraping. Collecting and re-plating rosette clusters after incubation with the STEMdiff™ Neural Rosette Selection Reagent will yield highly pure populations of neural progenitor cells, which can be further sub-cultured as single cells.

Functionalizing Ascl1 with Novel Intracellular Protein Delivery Technology for Promoting Neuronal Differentiation of Human Induced Pluripotent Stem Cells

Robinson M et al.


Pluripotent stem cells can become any cell type found in the body. Accordingly, one of the major challenges when working with pluripotent stem cells is producing a highly homogenous population of differentiated cells, which can then be used for downstream applications such as cell therapies or drug screening. The transcription factor Ascl1 plays a key role in neural development and previous work has shown that Ascl1 overexpression using viral vectors can reprogram fibroblasts directly into neurons. Here we report on how a recombinant version of the Ascl1 protein functionalized with intracellular protein delivery technology (Ascl1-IPTD) can be used to rapidly differentiate human induced pluripotent stem cells (hiPSCs) into neurons. We first evaluated a range of Ascl1-IPTD concentrations to determine the most effective amount for generating neurons from hiPSCs cultured in serum free media. Next, we looked at the frequency of Ascl1-IPTD supplementation in the media on differentiation and found that one time supplementation is sufficient enough to trigger the neural differentiation process. Ascl1-IPTD was efficiently taken up by the hiPSCs and enabled rapid differentiation into TUJ1-positive and NeuN-positive populations with neuronal morphology after 8 days. After 12 days of culture, hiPSC-derived neurons produced by Ascl1-IPTD treatment exhibited greater neurite length and higher numbers of branch points compared to neurons derived using a standard neural progenitor differentiation protocol. This work validates Ascl1-IPTD as a powerful tool for engineering neural tissue from pluripotent stem cells.

Spinal Muscular Atrophy Patient iPSC-Derived Motor Neurons Have Reduced Expression of Proteins Important in Neuronal Development.

Fuller HR et al.


Spinal muscular atrophy (SMA) is an inherited neuromuscular disease primarily characterized by degeneration of spinal motor neurons, and caused by reduced levels of the SMN protein. Previous studies to understand the proteomic consequences of reduced SMN have mostly utilized patient fibroblasts and animal models. We have derived human motor neurons from type I SMA and healthy controls by creating their induced pluripotent stem cells (iPSCs). Quantitative mass spectrometry of these cells revealed increased expression of 63 proteins in control motor neurons compared to respective fibroblasts, whereas 30 proteins were increased in SMA motor neurons vs. their fibroblasts. Notably, UBA1 was significantly decreased in SMA motor neurons, supporting evidence for ubiquitin pathway defects. Subcellular distribution of UBA1 was predominantly cytoplasmic in SMA motor neurons in contrast to nuclear in control motor neurons; suggestive of neurodevelopmental abnormalities. Many of the proteins that were decreased in SMA motor neurons, including beta III-tubulin and UCHL1, were associated with neurodevelopment and differentiation. These neuron-specific consequences of SMN depletion were not evident in fibroblasts, highlighting the importance of iPSC technology. The proteomic profiles identified here provide a useful resource to explore the molecular consequences of reduced SMN in motor neurons, and for the identification of novel biomarker and therapeutic targets for SMA.

Production of neural stem cells from human pluripotent stem cells

Wen Y and Jin S


Despite significant advances in commercially available media and kits and the differentiation approaches for human neural stem cell (NSC) generation, NSC production from the differentiation of human pluripotent stem cell (hPSC) is complicated by its time-consuming procedure, complex medium composition, and purification step. In this study, we developed a convenient and simplified NSC production protocol to meet the demand of NSC production. We demonstrated that NSCs can be generated efficiently without requirement of specific small molecules or embryoid body formation stage. Our experimental results suggest that a short suspension culture period may facilitate ectoderm lineage specification rather than endoderm or mesoderm lineage specification from hPSCs. The method developed in this study shortens the turnaround time of NSC production from both human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) differentiation. It provides a straightforward and useful strategy for generating NSCs that can benefit a wide range of research applications for human brain research.

Molecular effect of ethanol during neural differentiation of human embryonic stem cells in vitro.

Kim JJ et al.


Potential teratogenic effects of alcohol on fetal development have been documented. Especially studies have demonstrated deleterious effect of ethanol exposure on neuronal development in animal models and on the maintenance and differentiation of neuronal precursor cells derived from stem cells. To better understand the molecular effect of alcohol on the process of neural differentiation, we have performed gene expression microarray analysis on human embryonic stem cells being directed to neural rosettes and neural precursor cells in the presence of ethanol treatment. Here we provide detailed experimental methods, analysis and information associated with our data deposited into Gene Expression Omnibus (GEO) under GSE56906. Our data provide scientific insight on potential molecular effects of fetal alcohol exposure on neural differentiation of early embryo development.
