Figure 14 Has the myocardium its own stem cells? Arrows = C-Kit+ cells. C-Kit is an antigen of staminality. Its expression is a proof of staminal potential of these cells. These cells are still uncommitted. Arrowheads = cells expressing MEF2C. MEF2C is a transcription factor expressed early in the myocyte lineage. These cells are committed early to myocyte lineage. *Alpha-sarcomeric actin. This cell is engaged in a more advanced stage of myocyte lineage. Reprinted, with permission, from Beltrami et al. (66).
