Table 1. Effect of denervation on fiber diameters in tibialis anterior muscles.
Fiber diameter (µm)a | SEM | n | |
---|---|---|---|
WT, innervated | 55.3 | 5.85 | 3 |
WT, denervated | 33.3b | 5.44 | 3 |
trim63 −/−, innervated | 54.5 | 8.80 | 3 |
trim63 −/−, denervated | 53.1 | 3.48 | 3 |
a Maximal fiber diameters were obtained from confocal microscopy pictures of WT and trim63−/− mice that were denervated for 5 d and then imaged in vivo. b P < 0.05 for the difference between WT innervated vs. denervated, according to Welch test.
