Decreased whole-muscle function, but not single-fiber function, in satellite cell-depleted muscle 8 wk following SA surgery (SA-8). A) Specific force (kN/m2) in permeabilized single fibers isolated from the plantaris of vehicle-treated and satellite cell-depleted animals, presented as mean ± se specific force; n = 19–29 fibers/group. B) Specific force in the plantaris of vehicle-treated and satellite cell-depleted animals, presented as mean ± se specific force; n = 8 mice/group. †P < 0.05 for tamoxifen between condition-matched groups.
