Angus primary muscle cells grow faster than primary skeletal muscle cells derived from Hereford and WagyuX cattle.

The number of cells (cell index) was measured in culture using xCELLigence technology during two defined phases of growth. A. Proliferation Phase I (5–20 hours in culture) and B. Proliferation Phase II (20–72 hours in culture). (NOTE: Standard error bars in A and B are displayed as either positive or negative SE values only so the means are clearly visible and there is no overlap in error bars).
