Regulation of androgen receptor expression at the onset of functional overload in rat plantaris muscle. (bodybuilding.com)
Hence, muscle fiber hyperplasia and hypertrophy appear to contribute roughly equally to give the overall doubling of gastrocnemius / plantaris mass in Mstn − / − mice. (journals.plos.org)
For morphometric analysis, the gastrocnemius and plantaris muscles were sectioned serially to their widest point using a cryostat, and fiber diameters were measured (as the shortest distance across the fiber passing through the midpoint) from hematoxylin and eosin stained sections.
