In this Letter, Fig. 1b and Table 2 (summarizing experiments presented in Supplementary Figs 2–4 and 7–9) contained an error reflecting the total number of tumours formed, and the total number of injections with CD271+ cells isolated directly from patients (26 out of 37). The correct number is 25 out of 38. The total number of injections with CD271+ cells from xenografted tumours was incorrectly listed as 54 instead of 55, and the total number of injections with CD271 should have been 44 rather than 43. In Table 1 (summarizing experiments with xenografted tumours P0, Pi) the total number of injections with CD271+ cells was incorrectly listed as 36 instead of 37, and the total number of injections with CD271 cells should have been 26 rather than 25. In addition, in Fig. 3d the stacked bar column that shows the proportion of patients with different ranges of TYR positivity should indicate 19 instead of 17 for the 0%-positivity group, and 1 instead of 2 for the 90–98%-positivity group. Supplementary Table 3 also contained some errors. None of these alterations affect the significant differences or change the P value between CD271+ and CD271 cells in their ability to initiate melanomas in RG mice, as discussed in the original report. The corrected Figs 1b, 3d and Tables 1 and 2 are shown below.
