Electrical Stimulation of Human Connective Tissue Cells on Layers of Composite Structures with a Nanocarbon Framework

A technique for electrical stimulation of growth of connective tissue cells on composite structures with a nanocarbon framework was developed. Cells were stimulated with pulsed electric signal (amplitude, 200 mV; pulse duration, 2.5 ms) for 5 h. A study of the effect of the electrical stimulation on the viability of cells showed an increase in the proliferative activity and in the density of cells adhering to the surface of composite structure layers. The aspect ratio for the cell structure subjected to the electrical stimulation was 1.4 times greater than for nonstimulated cells. The developed technique can be used in tissue engineering, an important branch of regenerative medicine.
