title: Electric fields and proliferation in a dermal wound model: cell cycle kinetics.
abstract: In a dermal wound model, consisting of human skin fibroblasts in collagen matrix, continuous sinusoidal electrical current stimulation elicited a maximum increase of [3H]thymidine relative to control at 41 mV/m amplitude, 10 Hz. In this paper we elaborate cell cycle kinetics, using the same parameters. Labeling occurred over 4-h intervals beginning at 12 to 20 h after onset of electric exposure. The results suggest a significant increase in [3H]thymidine incorporation over an 8-h period extending from 16-24 hours after stimulus initiation.
