Introduction of Sensory Neurons

As an indispensable component for the functions of the neurons system and signal initiator in all reflex responses, sensory neurons are major responsible for conveying internal, external, and environmental stimuli to the central nervous system (CNS). Damage to sensory neurons can lead to many diseases, such as traumatic injury, toxin exposure, immune system disorders, and metabolic disease. The subsequent cellular dysfunction leads to a loss of coordination involuntary movement. The in vitro source of human sensory neurons present great potentials in the generation of functional human CNS disease models for drug discovery and pathological studies.

During the developmental stages of sensory neurons, a series of crucial signaling pathways are revealed. For example, the combination of Wnt signaling pathways and the TGF β super-family is important for sensory neuron differentiation. The neurotrophic factors for sensory neurons differentiation may include nerve growth factor (NGF), neurotrophin 3 (NT3), brain-derived neurotrophic factor (BDNF), and glial cell line-derived neurotrophic factor (GDNF).

The process of sensory neurons generation from embryonic stem cells (ESCs) contain three stages:

  • The induction of neural ectoderm to distinguish the developing nervous system;
  • The induction of neural crest cell fate to segregate the peripheral nervous system (PNS) from CNS;
  • The specification of sensory neurons to distinguish them from other neural crest derivatives.

Our Sensory Neuron Progenitor Differentiation Service

We are thrilled to present our service, which is dedicated to the differentiation of sensory neuron progenitors. Our sensory neuron progenitors differentiation service is designed to generate high-quality, functional sensory neurons from various sources such as iPSCs or ESCs. Utilizing state-of-the-art facilities and innovative techniques, we employ a multidisciplinary approach to guide the cellular development pathway optimally.

Sensory Neurons Differentiation Methods

It has been proved that the functional sensory neurons can be generated from a human neural progenitor cell line hNP1, which is derived from the human embryonic stem cell line WA09. According to the cell treatment with trophic factors and chemicals that have shown important roles in sensory neurons generation, the hNP1 cell line is induced to generate sensory neurons. The immunocytochemical analysis is then used to confirm the identity of the sensory neurons. And the functional maturation of the differentiated sensory neurons can be determined by electrophysiological analysis. Compared with ESCs, the neural progenitor-based sensory neurons induction is simple, efficient, and faster. In addition, skin-derived precursor cells (SKP), as a type of neural crest stem cells, are also an important source of sensory neurons.

In conclusion, the generation of functional sensory neurons provides valuable tools for the simulation of in vitro functions of sensory neuron-related neural circuits and the treatment of related diseases.

Published Data

Erica L. et al. investigated the effect of the number of iPSC passages on sensory neuron differentiation. They assessed the morphology and pluripotency of iPSC prior to differentiation and evaluated differentiated sensory neurons based on electrophysiological properties and expression of key neuronal markers.

As shown in the figure, iPSC-dSN differentiated from low transmission generations exhibited better electrophysiological maturation. Combined with other characterization data, it is concluded that iPSC-dSN differentiated from low passages better encapsulates the sensory neuron phenotype than iPSC-dSN differentiated from medium or high passages. A lower number of passages may be more suitable for differentiation into peripheral sensory neurons.
