Torn supraspinatus muscle vs. intact subscapularis muscle in rotator cuff tears patients. Homo sapiens

Rotator cuff tear is a common disease in elderly patients. The satellite cell has central role of muscle regeneration, however, there are few reports about human muscle. The purpose of this study was to compare features of human myogenic and adipogenic precursors in both torn supraspinatus (SSP) and intact subscapularis (SSC). Comprehensive gene expression patterns were compared between SSP and SSC muscles by microarray analisys. Overall design: Two-condition experiment, torn supraspinatus muscle vs. intact subscapularis muscle. Two patients. 2 replicates (dye-swap) for each patient.
