Electrically induced neurite outgrowth of PC12 cells on the electrode surface

Med Biol Eng Comput. 1998 Jul;36(4):493-8. doi: 10.1007/BF02523221.

Abstract

Morphological differentiation of PC12 cells cultured on an indium-tin oxide (ITO) electrode has been induced to grow neurites in the absence of nerve growth factor (NGF) by electrical stimulation. Rectangular pulse wave potentials were applied to the electrode at amplitudes of 200 mV and 400 mV with frequencies of 50 Hz, 500 Hz, and 1 kHz. The PC12 cells differentiated most prominently at 200 mV with 100 Hz. No statistically significant differences were observed among the electrically induced neurite lengths. The electrically induced differentiation was completely inhibited by a blockade of calcium influx using LaCl3. This indicates that repeated potential shift in the vicinity of a cellular membrane may stimulate morphological response, probably through calcium ion channels.
