Figure 3.

Muscle fiber characteristics indexes and mRNA expression levels about muscle fiber development of Nile tilapia. (A) Fiber density, (B) frequency of muscle fiber, (C) sarcomere length, and (D) mRNA expression levels about muscle fiber development of Nile tilapia. Data values are means (n = 3), with their standard deviations (SDs) represented by vertical bars. Bar graphs of the same color, but with different letters are significantly different (p < 0.05). myf5, myogenic factor 5; myf6, myogenic factor 6; myod, myogenic differentiation 1; myog, myogenin.
