Abstract:
The fusion of myoblasts, the skeletal muscle progenitors, is critical for skeletal muscle formation, function, and repair after muscle injury. Recognition of the phospholipid phosphatidylserine (PtdSer) exposed on certain myoblasts is required during fusion into multinuclear myofibers. Cell surface exposure of PtdSer is also a feature of cells dying through the process of apoptosis. Here, we describe the use of PtdSer exposing apoptotic cells as stimulators of myoblast fusion.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
