Overview

STEMdiff™ SMADi Neural Induction Kit consists of a defined, serum-free medium and supplement for the highly efficient neural induction of human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells. This kit combines STEMdiff™ Neural Induction Medium (Catalog #05835) with STEMdiff™ SMADi Neural Induction Supplement, which directs differentiation by blocking TGF-β/BMP-dependent SMAD signaling, resulting in efficient neural induction of even hard-to-differentiate cell lines. Neural progenitor cells (NPCs) can be generated using STEMdiff™ SMADi Neural Induction Kit with either an embryoid body (EB) protocol or monolayer culture protocol. The resulting cultures are enriched for central nervous system (CNS)-type NPCs, which express SOX1, Nestin, and PAX6. NPCs generated using this kit can be passaged as single cells and expanded in STEMdiff™ Neural Progenitor Medium (Catalog #05833). The NPCs can also be differentiated into neurons and glia.

Data Figures

Figure 1. STEMdiff™ SMADi Neural Induction Kit Supports Generation of Neural Progenitor Cells with High Levels of PAX6 and SOX1 Expression.

Neural progenitor cells (NPCs) can be generated from hPSCs cultured in mTeSR™1 or TeSR™-E8™ via embryoid body or monolayer protocol using the STEMdiff™ SMADi Neural Induction Kit. Resulting NPCs express CNS-type NPC markers PAX6 and SOX1.

Figure 2. STEMdiff™ SMADi Neural Induction Kit Supports Robust Neural Progenitor Cell Generation Across Multiple hPSC Lines.

Multiple human ES and iPS lines (cultured in mTeSR™1 or TeSR™-E8™) were subjected to the monolayer neural induction protocol. Cells were harvested after 7 days in culture and processed for immunostaining with PAX6, SOX1 and SOX10 antibodies. Cultures were imaged and quantified using the high content imager ImageXpress Micro, which counts positive nuclei across the entirety of the culture well. n=3 replicates per cell line. Data showed that neural progenitor cells produced using the STEMdiff™ SMADi Neural Induction Kit expressed very high levels of CNS-type markers PAX6 and SOX1, while the neural crest marker SOX10 was low to undetectable.

Starting hPSCs were maintained in mTeSR™1 and differentiated using an embryoid body (EB) protocol. Resulting cells were differentiated using the STEMdiff™ Neuron Differentiation/Maturation Kits, STEMdiff™ Astrocyte Differentiation/Maturation Kits, and STEMdiff™ Dopaminergic Neuron Differentiation/Maturation Kits as per the respective protocols.

Consequences of the Novel ALS-Associated KIF5A Variant c.2993-6C > A for Exon 27 Splicing and Axonal Transport of SFPQ G. A. Rouleau et al. Neurology: Genetics 2026 Mar

Abstract

Background and Objectives: Recent studies have identified variants in the kinesin family member 5A (KIF5A) gene that predispose to amyotrophic lateral sclerosis (ALS). These ALS-linked KIF5A variants lead to the exclusion of exon 27, resulting in the production of a mutated protein with an altered C-terminal region (KIF5A ΔExon27). Through whole genome sequencing, we identified a novel KIF5A intronic variant, rs1057522322 (c.2993-6C > A; chr12:57582596C > A, GRCh38.p14), in a family segregating ALS. Our goal is to investigate the effect of this variant on exon 27 splicing and to assess its functional consequences on KIF5A-mediated cargo transport. Methods: Induced pluripotent stem cells (iPSCs) were generated from siblings with and without the c.2993-6C > A variant. RT-PCR was performed on RNA extracted from iPSC-derived neurons to assess exon 27 splicing. Functional studies were conducted on iPSC-derived motor neurons (MNs). Results: RT-PCR confirmed that the c.2993-6C > A variant induced exon 27 skipping in KIF5A. Immunofluorescent staining showed that KIF5A ΔExon27 abolished the axonal interaction with splicing factor proline- and glutamine-rich, a cargo specifically transported by KIF5A. Under stress conditions, MNs carrying the c.2993-6C > A variant exhibited TDP-43 proteinopathy. Discussion: KIF5A intronic variant c.2993-6C > A could be a risk factor for ALS. KIF5A ΔExon27 impairs KIF5A-mediated cargo transport and contributes to ALS pathogenesis in a TDP-43–dependent manner.
Development of potent, selective cPLA2 inhibitors for targeting neuroinflammation in Alzheimer’s disease and other neurodegenerative disorders A. V. Sadybekov et al. Npj Drug Discovery 2026 Jan

Abstract

Chronic neuroinflammation plays a key role in the progression of Alzheimer’s disease (AD), and the cytosolic calcium-dependent phospholipase A2 (cPLA2) enzyme is a critical mediator of inflammatory lipid signaling pathways. Here we investigate the therapeutic potential of novel cPLA2 inhibitors in modulating neuroinflammation in AD. By leveraging the giga-scale V-SYNTHES2 virtual screening in on-demand chemical space and conducting two rounds of optimization for potency and selectivity, we have identified BRI-50460, achieving an IC50 of 0.88 nM in cellular assays that measure cPLA2-mediated arachidonic acid release. In vivo studies revealed favorable brain-to-plasma ratios, highlighting the ability of BRI-50460 to penetrate the central nervous system, modulating neuroinflammatory pathways, and restoring lipid homeostasis. In astrocytes and neurons derived from human induced pluripotent stem cells, BRI-50460 mitigates the effects of amyloid beta 42 oligomers on cPLA2 activation, tau hyperphosphorylation, and synaptic loss. Our results support that small molecule inhibitors of cPLA2 can modulate the downstream inflammatory signaling, offering a promising therapeutic strategy for neurodegenerative diseases.
Modeling neurovascular dysfunction in Alzheimer’s disease using an isogenic brain-chip model A. N. Shen et al. Fluids and Barriers of the CNS 2026 Jan

Abstract

Background: The pathology of Alzheimer’s Disease (AD) is characterized by aggregates of amyloid beta (Aβ) peptides and neurofibrillary tau tangles. Increased blood-brain barrier (BBB) permeability and reduced Aβ clearance, which signal neurovascular dysfunction, have also been proposed as early markers of AD. Despite intense scrutiny, the mechanisms of AD remain elusive and novel treatments that address core symptoms of dementia are limited. New alternative methods (NAMs) aim to develop in-vitro translational models that recapitulate human pathology more accurately than previous models and could contribute to the development of new therapies. Methods: Here, we developed a NAM model of the cortical neurovascular unit (NVU) using brain cells derived from human induced pluripotent stem cells (hiPSCs) from a patient with AD and a healthy individual. Differentiated neurons, astrocytes, pericytes, microglia, and brain-like microvascular endothelial cells were cultured in a microphysiological system to create a brain-chip model to evaluate NVU-related endpoints. Results: Compared to control, AD brain-chips had reduced claudin-5 and ZO-1 expression and increased paracellular permeability. AD brain-chips also had decreased activity of the efflux transporter P-glycoprotein (P-gp), but its expression was unchanged. In AD brain-chips, levels of Aβ42, total tau, and p-tau 181 were decreased in protein lysates from the brain channel, while levels of total tau and p-tau 181 were increased in protein lysates from the vascular channel. Finally, AD brain-chips had increased levels of the proinflammatory markers IL-6 and MCP-1 in effluent from both brain and vascular channels. Conclusion: In this brain-chip model, we showed Aβ-independent NVU dysfunction that was related to neuroinflammation and vascular tau accumulation. This study demonstrates the utility of the brain-chip model to evaluate changes in NVU functions induced by AD-like pathology and highlights donor-specific responses associated with the use of hiPSC-derived models.
