The intersection of disuse-induced muscle atrophy and satellite cell content: reply to Snijders, Nederveen, and Parise.

to the editor: We thank Snijders et al. ([5][1]) for raising important questions worthy of further discussion. In our study, 14 days of bed rest induced robust myofiber atrophy and muscle weakness that was accompanied by a reduction in satellite cell content ([1][2]). Individual changes in satellite
