In the original version of this published article, the authors mistakenly duplicated one of the images in Figure 2A due to a copy‐and‐paste error. The correct image from that experiment is shown below. This correction does not change the result and conclusion. We apologize for any confusion it may have caused.

In addition, in Figure 2B, by mistake, the data were not calculated from the experiment which was presented in Figure 2A (cell line EC9706), but from a related experiment which we conducted on another esophageal cancer cell line, KYSE150. The reason for using KYSE150 for a similar experiment as we did with EC9706 was that we wanted to confirm our conclusion from multiple cell lines not only from EC9706. The present data from KYSE150 in Figure 2B showed a similar significant difference in SP and non‐SP cells in response to IR‐induced DNA damage, demonstrating that SP cells from KYSE150 were also resistant to DNA damage induced reduction in colony formation. The data from KYSE150 supported very well our conclusions in the paper. However, to make the data more uniform, we decided to only present the data from EC9706. The correct data and graph that were calculated from the exact same experiment on EC9706 presented in Figure 2A is shown below. This correction does not change the result and conclusion. We apologize for any confusion it may have caused.

在此发表文章的原始版本中，由于复制和粘贴错误，作者错误地复制了图2A中的一张图像。该实验的正确图像如下所示。此更正不会更改结果和结论。如果造成任何混乱，我们深表歉意。

另外，错误地在图2B中，数据不是根据图2A中所示的实验（细胞系EC9706）计算的，而是根据我们对另一种食道癌细胞系KYSE150进行的相关实验计算的。之所以将KYSE150用于与EC9706相似的实验，是因为我们想从多个细胞系中不仅从EC9706来证实我们的结论。图2B中来自KYSE150的当前数据显示，SP和非SP细胞对IR诱导的DNA损伤有相似的显着差异，表明来自KYSE150的SP细胞也对DNA损伤诱导的菌落形成减少有抵抗力。来自KYSE150的数据很好地支持了本文的结论。但是，为了使数据更统一，我们决定仅显示EC9706中的数据。从图2A所示的EC9706的完全相同的实验中计算出的正确数据和图表如下所示。此更正不会更改结果和结论。如果造成任何混乱，我们深表歉意。
