FIG. 3.

Time course of the effect of alternating electric current duration of exposure on the osteodifferentiation of adult hMSC. For the three frames of Figure 3: The axes indicate fold change compared to the “baseline,” that is, results obtained from adult hMSCs in numbers similar to those seeded on ITO-glass (on day 0), but not exposed alternating electric current. (A) Effect of the duration of exposure on the osteodifferentiation of adult hMSCs at 7 days of culture. Adult hMSCs were exposed to 10 μA, 10 Hz alternating electric current for either 3 h (red line) or 6 h (blue line) daily at 7 days of culture. (B) Effect of the duration of exposure on the osteodifferentiation of adult hMSCs at 14 days of culture. Adult hMSCs were exposed to 10 μA, 10 Hz alternating electric current for either 3 h (red line) or 6 h (blue line) daily at 14 days of culture. (C) Effect of the duration of exposure on the osteodifferentiation of adult hMSCs at 21 days of culture. Adult hMSCs were exposed to 10 μA, 10 Hz alternating electric current for either 3 h (red line) or 6 h (blue line) daily at 21 days of culture. Color images available online at www.liebertpub.com/tec
