Generation of Neural Crest Cells

Induced pluripotent stem cells (iPSCs) offer a transformative platform for generating a wide range of cell types, including neural crest cells, which are pivotal in developmental biology and disease modeling. At Creative Biolabs, we provide a robust and customizable protocol for generating highly pure, functional neural crest cells from iPSCs, supporting cutting-edge research in neural development, regenerative medicine, and neural crest-derived pathologies.

Overview of the Generation of Neural Crest Cells

Neural crest cells are a transient, multipotent, and migratory cell population that arise during vertebrate embryogenesis from the border region between the neural plate and non-neural ectoderm. They possess the remarkable ability to differentiate into a wide range of cell types, including peripheral neurons, glial cells, melanocytes, craniofacial cartilage, bone, and smooth muscle. Due to their extraordinary lineage potential and contribution to diverse tissues, neural crest cells are often referred to as the "fourth germ layer."

In vitro differentiation of neural crest cells from iPSCs closely mimics the in vivo developmental cues responsible for neural crest specification. This process involves a tightly regulated sequence of steps including:

• Transitioning iPSCs into anterior neuroectoderm by dual inhibition of SMAD signaling.
• Activation of Wnt and BMP signaling pathways to specify the neural plate border region.
• Commitment to neural crest cells fate through upregulation of transcription factors like SOX10, FOXD3, and SNAI2, followed by acquisition of migratory properties.

By recapitulating these developmental signaling pathways using small molecules, neural crest cells can be efficiently and reproducibly derived from iPSCs in a chemically defined, feeder-free system. This eliminates the variability associated with embryoid body formation or serum-based differentiation protocols.

We provide a high-efficiency, customizable neural crest cell differentiation protocol tailored to both basic research and translational applications. Our platform ensures:

• High induction efficiency across multiple iPSC lines
• Chemically defined and xeno-free differentiation conditions
• Downstream scalability and lineage flexibility

By unlocking the developmental blueprint of neural crest formation through iPSC technology, Creative Biolabs empowers researchers and developers to advance their scientific goals.

Materials and Reagents

Below is a non-exhaustive list of essential reagents and media required for sensory neuron differentiation.

Protocol Steps

Maintenance of Undifferentiated iPSCs

Coat plates with Matrigel in DMEM/F12 and incubate. Plate iPSCs in mTeSR1 medium, changing medium daily. Maintain cells at ~70–80% confluency to avoid spontaneous differentiation. Passage with Accutase every 4–5 days using ROCK inhibitor to promote survival.

Neural Induction Phase

Replace mTeSR1 with neural induction medium: DMEM/F12 + N2 supplement + SB431542 + CHIR99021. Incubate for 5 days, refreshing medium every 24 hours. Observe morphological changes: cells flatten, gain rosette-like morphology.

Neural Crest Specification

Promote neural crest cell lineage commitment from anterior neuroectoderm. On Day 5, switch to neural crest cell induction medium: Neurobasal medium + B27 (–Vit A) + N2 + CHIR99021 + SB431542. Continue culture for 5 additional days. Monitor for NCC morphology (elongated, migratory phenotype).

Expansion and Enrichment of NCCs

Detach cells using Accutase and re-plate on fibronectin-coated plates. Culture in neural crest cell expansion medium: DMEM/F12 + N2/B27 + bFGF + EGF. NCC markers (SOX10, HNK-1, p75NTR) typically peak during this phase.
