Area of Science:

Biomaterials Science
Stem Cell Biology
Cancer Research

Background:

The cell/material interface influences cell function.
Cancer stem-like cells (CSCs) are crucial in tumor growth and recurrence.
Regulating CSC differentiation is a key therapeutic goal.

Purpose of the Study:

To investigate if the electrical cell/material interface can regulate CSC differentiation.
To explore the use of electrospun polymer scaffolds with graphene nanoplatelets (GnPs) for CSC differentiation.
To examine the impact of these scaffolds on glioblastoma multiforme (GBM) CSCs.

Main Methods:

Fabrication of electrospun polyamide 66 or poly(lactic acid) fibers with embedded GnPs.
Culturing and analysis of CSCs from a human GBM cell line on these scaffolds.
Assessment of CSC morphological, immunostaining, and electrophysiological properties.

Main Results:

GnP-incorporating scaffolds promoted CSC differentiation towards the glial phenotype.
Scaffolds provided a suitable 3D and electrical microenvironment for CSCs.
Numerical simulations indicated electrical interface-induced membrane potential hyperpolarization triggered differentiation.

Conclusions:

The electrical cell/material interface can regulate CSC differentiation by manipulating membrane potential.
Material-induced differentiation of CSCs presents novel avenues for tissue engineering and cancer therapy, particularly for GBM.
This approach offers a new strategy for cancer treatment by controlling CSC behavior.
