Secretion of contraction-inducible myokines from hybrid myotubes comprised of C2C12 cells and human muscle cells obtained from a biopsy sample. After 7–8 days of differentiation, the differentiated myotubes originating from murine C2C12 cells and human primary myoblasts obtained from a biopsy sample (seeded in the 4 individual wells of 2 distinct culture plates) were treated with (n = 4) or without (n = 4) EPS at 20 V/25 mm, 1 Hz, 4-ms duration for 16 h. Conditioned media were collected and subjected to the 40-Plex BioPlex assay (*P < 0.05, n = 4). Two independent experiments using the same cell stock sample were performed, and representative results are shown. The Movement Index is also shown in the BOX.
