Effects of biological intensity electric field on motility and CD9 expression of human epidermal cell line HaCaT and mouse epidermal cells

" Both HaCaT cells and mouse epidermal cells were divided into sham EF group (simulated operation) and 50 mV/mm group, 100 mV/mm group, 200 mV/mm group and 400 mV/mm group treated with EF in the corresponding intensity respectively."

" The biological intensity EF can induce the directional migration and arrangement of HaCaT cells and down regulate the expression of CD9 in HaCaT cells and mouse epidermal cells in a time-dependent and intensity-dependent manner."
