Satellite cell content is specifically reduced in type II skeletal muscle fibers in the elderly
Open accessAbstract
Satellite cells (SC) are essential for skeletal muscle growth and repair. Because sarcopenia is associated with type II muscle fiber atrophy, we hypothesized that SC content is specifically reduced in the type II fibers in the elderly. A total of eight elderly (E; 76 ± 1 yr) and eight young (Y; 20 ± 1 yr) healthy males were selected. Muscle biopsies were collected from the vastus lateralis in both legs. ATPase staining and a pax7-antibody were used to determine fiber type-specific SC content (i.e., pax7-positive SC) on serial muscle cross sections. In contrast to the type I fibers, the proportion and mean cross-sectional area of the type II fibers were substantially reduced in E vs. Y. The number of SC per type I fiber was similar in E and Y. However, the number of SC per type II fiber was substantially lower in E vs. Y (0.044 ± 0.003 vs. 0.080 ± 0.007; P < 0.01). In addition, in the type II fibers, the number of SC relative to the total number of nuclei and the number of SC per fiber area were also significantly lower in E. This study is the first to show type II fiber atrophy in the elderly to be associated with a fiber type-specific decline in SC content. The latter is evident when SC content is expressed per fiber or per fiber area. The decline in SC content might be an important factor in the etiology of type II muscle fiber atrophy, which accompanies the loss of skeletal muscle with aging.

In the citing paper
“The reduction in these cells has been explicitly shown in type II fibers more than in type I during aging [87, 117].”
From The critical role of oxidative stress in sarcopenic obesity (2021) · cites this paper as [117]
In the citing paper
“Sarcopenia is phenotypically associated with decreased muscle fiber size and shifts in fiber type change from fast to slow, resulting in a decrease in maximal muscle force production [14,15].”
From Potential Roles of n-3 PUFAs during Skeletal Muscle Growth and Regeneration (2018) · cites this paper as [14]
In the citing paper
“These changes are also accompanied by a diminished regenerative capacity of the muscle due to a loss in the number and activity of satellite cells in type II “fast” fibers [14,16,17].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
