In the published article the bar graphs of the original Figure 6D and Figure 6H were accidentally swapped during figure preparation. The bar graph and y-axis scale given in Fig. 6H belong to the labeling of Fig. 6D and vice versa. In the published Fig. 7C the indicated number of totally counted cells, N, was slightly higher than originally reported and has been corrected. The corrected figures 6D, 6H, and 7C appear below. The authors state that the conclusions of the article are not affected by the corrections.
