Overview

Reduce the risk of culture failure by maturing and maintaining motor neuron cells using the STEMdiff™ Motor Neuron Maturation Kit. This kit combines neurophysiological BrainPhys™ Medium (Catalog #05790)—proven to support long-term activity and maturation—with the supplements needed to produce functional motor neuron cultures.

Cells matured with the STEMdiff™ Motor Neuron Maturation Kit exhibit high-level expression of expected motor neuron markers, including ChAT (>40%), across multiple cell lines. Use the resulting motor neuron cultures in a variety of applications, such as modeling human neurological disease or toxicity testing. The STEMdiff™ Motor Neuron Maturation Kit can also support your co-culture with muscle cells generated using the MyoCult™ Differentiation Kit (Catalog #05965) or with microglia generated using the STEMdiff™ Microglia Differentiation Kit (Catalog #100-0019).

Experimental Protocol for STEMdiff™ Motor Neuron Differentiation and Maturation Kits

Figure 1. Schematic for the STEMdiff™ Motor Neuron Culture System Protocol

Motor neurons can be generated from human pluripotent stem cells (hPSCs) in 14 days. The resulting cells can then be matured for an additional 14 or more days using STEMdiff™ Motor Neuron Maturation Kit.

Motor Neuron Progenitors With >60% OLIG2+ Expression Created Using the STEMdiff™ Motor Neuron Differentiation Kit

Figure 2. Pure Population of Motor Neuron Progenitors Are Generated Using the STEMdiff™ Motor Neuron Differentiation Kit

hPSCs from a variety of cell lines were differentiated to motor neuron progenitors using the STEMdiff™ Motor Neuron Differentiation Kit in an ultra-low attachment or an AggreWell™400 plate. (A) hPSCs maintained in mTeSR™1 or mTeSR™ Plus were aggregated to EBs with the STEMdiff™ Motor Neuron Differentiation Kit. On Day 9, EBs were dissociated into single cells and replated for adherent culture.The resulting cultures contain a population of cells expressing motor neuron progenitor marker OLIG2 (red) and are negative for spinal interneuron marker NKX2.2 (green). Nuclei are labeled with Hoechst (blue). (B) The percentage expression of OLIG2 and negative controls NKX2.2, FOXG1, OTX1, and OTX2 in the resulting cultures, derived from 2 hES (H1 and H7) and 2 hiPS (WLS-1C and STiPS-M001) cell lines, were quantified. This differentiation generated OLIG2+ motor neuron progenitors (83.20% ± 2.890%, mean ± SEM; n=4 cell lines, 2 replicates per condition). Numbers are % positive of total Hoechst-positive cells. hPSCs = human pluripotent stem cells; EB = embryoid body

Motor neuron progenitors derived from a variety of cell lines were transitioned to post-mitotic motor neurons using the STEMdiff™ Motor Neuron Differentiation Kit.

This differentiation generated βIII-TUB+ (92.59% ± 1.079%, mean ± SEM; n=6 cell lines, 2 replicates per condition), ISL1+ (55.99% ± 3.723%, mean ± SEM), and HB9+ (65.17% ± 3.514%, mean ± SEM) motor neurons.

Bulk RNA-seq heatmap showing that STEMdiff™ Motor Neurons express expected markers at various time points.

Figure 8. STEMdiff™ Motor Neurons Express Expected Motor Neuron Markers

Motor neurons were generated from iPS cell lines STiPS-R038, STiPS-M001, SCTi003-A (all maintained in mTeSR™ Plus), and SCTi003-A (maintained in mTeSR™1). hPSCs were then differentiated with the STEMdiff™ Motor Neuron culture system. RNA from Day 9, Day 14, and mature (in maturation media for 14 days) motor neurons was harvested and subsequently assayed using bulk RNA-seq. Their transcriptomic profiles were also compared to a parent hPSC control. The heat map displays expression levels for select genes associated with hPSCs, motor neuron progenitors, and motor neurons. iPS = induced pluripotent stem; hPSC = human pluripotent stem cell
