In contrast, a similar analysis of F66 transgenic mice revealed that although total fiber number was increased slightly (16 %), the overall increase in gastrocnemius /
plantaris mass resulted almost entirely from muscle fiber hypertrophy (93 % increase in cross-sectional area).
Hence, muscle fiber hyperplasia and hypertrophy appear to contribute roughly equally to give the overall doubling of gastrocnemius /
plantaris mass in Mstn − / − mice.

To determine whether the same is true for the additional muscle
mass seen upon introduction of the F66 transgene, I carried out morphometric analysis of the gastrocnemius /
plantaris muscles.
