14 days of bed rest induces a nonsignificant reduction in MyoD-positive satellite cells. A: representative immunohistochemical image demonstrating laminin (green), MyHC type 1 (pink), MyoD (white), and DAPI (blue). A MyoD-positive satellite cell associated with a MyHC type 1 fiber (white arrowhead) is identified. Scale bar = 50 μm. B: quantification of fiber type-specific MyoD-positive satellite cell content, expressed as mean satellite cells per fiber ± SE. C: quantification of MyoD-positive satellite cell content, expressed as mean satellite cells per fiber ± SE.
