On-Chip Neural Induction Boosts Neural Stem Cell Commitment: Toward a Pipeline for iPSC-Based Therapies.

The clinical translation of induced pluripotent stem cells (iPSCs) holds great potential for personalized therapeutics. However, one of the main obstacles is that the current workflow to generate iPSCs is expensive, time-consuming, and requires standardization. A simplified and cost-effective microfluidic approach is presented for reprogramming fibroblasts into iPSCs and their subsequent differentiation into neural stem cells (NSCs).

FriendlyClearMap: an optimized toolkit for mouse brain mapping and analysis.

Background: Tissue clearing is currently revolutionizing neuroanatomy by enabling organ-level imaging with cellular resolution. However, currently available tools for data analysis require a significant time investment for training and adaptation to each laboratory's use case, which limits productivity. Here, we present FriendlyClearMap, an integrated toolset that makes ClearMap1 and ClearMap2's CellMap pipeline easier to use, extends its functions, and provides Docker Images from which it can be run with minimal time investment.

Generation of glutamatergic/GABAergic neuronal co-cultures derived from human induced pluripotent stem cells for characterizing E/I balance in vitro.

Obtaining mechanistic insights into the disruptions of neuronal excitation and inhibition (E/I) balance in brain disorders has remained challenging. Here, we present a protocol for in vitro characterization of E/I balance. Using human induced pluripotent stem cells, we describe the generation of glutamatergic excitatory/GABAergic inhibitory neuronal co-cultures at defined ratios, followed by analyzing E/I network properties using immunocytochemistry and multi-electrode array recording.

EHMT1 regulates Parvalbumin-positive interneuron development and GABAergic input in sensory cortical areas.

Mutations in the Euchromatic Histone Methyltransferase 1 (EHMT1) gene cause Kleefstra syndrome, a rare form of intellectual disability (ID) with strong autistic traits and sensory processing deficits. Proper development of inhibitory interneurons is crucial for sensory function. Here we report a timeline of Parvalbumin-positive (PV) interneuron development in the three most important sensory cortical areas in the Ehmt1 mouse.
