Terminal deoxynucleotidyl transferase (TdT)-mediated 2′-deoxyuridine 5′-triphosphate (dUTP) nick end labeling (TUNEL) staining was conducted in order to detect the apoptosis of skeletal muscle cells, which showed that the number of apoptotic cells increased significantly in the sepsis group (Figure 1D). Here, DNTT is linked to Sepsis.
