Background:

Physiological electric fields (EF) are crucial for cellular functions like migration and differentiation.
Controlling cell fate is essential for regenerative medicine and understanding developmental processes.

Purpose of the Study:

To develop and utilize a microfluidic system for long-term cell differentiation studies.
To investigate the effect of direct current (DC) pulse stimulation on neural stem and progenitor cell (NPC) differentiation.

Main Methods:

A microfluidic electrotactic chip system was designed with components for controlled electrical stimulation and microscopy.
Mouse NPCs (mNPCs) were cultured and subjected to DC pulse stimulation in a stem cell maintenance medium.
Time-lapse imaging and microscopy were employed to observe and analyze cell differentiation.

Main Results:

The microfluidic system enabled simplified experimental setups, reduced reagent consumption, and allowed for precise control of the cellular microenvironment.
DC pulse stimulation effectively induced differentiation of mNPCs into neurons, astrocytes, and oligodendrocytes.
The system facilitated long-term cell culture, EF stimulation, and automated image acquisition.

Conclusions:

Simple DC pulse stimulation is a viable method to control the differentiation fate of neural stem and progenitor cells.
This microfluidic system offers a promising platform for developing therapeutic strategies for nervous system disorders.
The system enhances experimental efficiency and accuracy in cell differentiation studies.
