Neuron-On-A-Chip Model Development Service
Inquiry
Neuromuscular diseases span a wide range of rare conditions, and Creative Biolabs now provides the neuron-on-a-chip model as a powerful tool for exploring their etiology and complex pathophysiology.
Advantages of Neuron-On-A-Chip Model
The gold standard for neurological disease modeling is often animal models, especially humanized mice, but the disease phenotypes induced by animals are often very different from humans in terms of progression and severity. However, simple two-dimensional in vitro culture cannot reproduce human genetics, anatomy and physiological characteristics, and the growing neural network is chaotic and lacks the reproducibility of an experimental model. In contrast, neuron-on-a-chip model can reproduce human body signs, induce nerve cell differentiation and synapse growth with economic and research value. Since the complete isolation of primary motor neurons from humans remains histologically infeasible, neurochips increasingly use neuroblastoma cells or mouse embryonic motor neurons, which retain proliferative properties while exhibiting specific neuronal properties such as acetylcholine synthesis, neurofilament protein expression, and neurotransmitter release.

Typical Neuron-On-A-Chip Model
Standardized neural chips often use a multi-chamber structure. Multiple culture chambers are connected by narrow channels, and the specific growth of axons can be achieved by controlling the height and length of the channels. When the height of the microchannel is less than 5 μm, only neurites can enter the tunnel, and when the length of the microchannel exceeds 400 μm, only axons can extend into another chamber. Our dual-chamber neuron chips enable controlled axon growth and signal propagation in desired directions. The transparent chip structure also allows direct visualization of cell growth or protein expression. This chip is suitable for a variety of culture experiments, including axon growth, axon transport, synaptic manipulation, neuronal migration, and neuronal/non-neuronal interactions.

Advanced Neuron-On-A-Chip Model
Advances in soft lithography and surface biofunctionalization have made microfluidic channel devices with different patterns a reality, and microchannel networks with specific pattern structures often have better operability and accessibility. Through our neurochip customization service, you can design the pattern shape and topology of the chip yourself to achieve controlled growth of cell bodies and neurite extensions, and nerve cells will exhibit neuron polarity in a specific direction and elongate in the expected direction. The integration of electrophysiological components and chemical gradient generation components allows your experiments to explore the relationship between the microenvironment and cellular function in greater depth and breadth.
