Figure 1.
A subpopulation with increased resting [Ca2+]i appears in fusing myoblasts. Myoblasts have been distributed in 16 bins of 10 nM according to their resting [Ca2+]i. Distributions were fitted with either a simple (Inset, undifferentiated myoblasts: UD-MB) or a double (fusion-competent myoblasts: FC-MB) Gaussian equation. To emphasize the difference, the double Gaussian fit from the main graph is shown in the inset as a broken line.
