Abstract (original English)
Background The development of tissue-engineered scaffolds with electrical properties is the primary motivation of novel regenerative medicine. Electroconductive scaffolds are designed to mimic the injured tissue environment's electrical properties and regulate cellular behavior - growth, proliferation, and differentiation - that could stimulate the injured nerve's regeneration. Methods We fabricated dedicated electroconductive scaffolds and customized an appropriate device with an external current supply to expose cells on the scaffold to electrical stimulation (ES). Next, we isolated rat adipose-derived stem cells (ASCs) and performed in vitro experiments that combine cells, an electroconductive scaffold, NGF (nerve growth factor), and ES (90 mV/mm, constant, for four days). Finally, we checked cellular activity as proliferation, viability, morphology, the neurogenic differentiation potential of ASCs, cell alignment, and karyotype. Results We observed that the electrical stimulation did not change the viability and chromosome stability of rat ASCs, but altered slightly proliferation compared to non-stimulated cells. The combined effect of a scaffold, NGF, and ES caused morphology changes and enhancement of ASCs neuronal differentiation as indicated in βIII-tubulin expression, actin organization, and upregulation of neurogenic gene expression. Conclusions We developed an electr
