Change Type: Erratum
Change Details: In the version of this article initially published, the sentence "This method was also used for MARS-seq (massively parallel scRNA-seq)<sup>33</sup>, and later for InDrop (droplet sequencing)34 and Seq-Well (a well-array-based variation on MARS-seq)<sup>35</sup>" was incorrect. The words "and Seq-Well (a well-array-based variation on MARS-seq)<sup>35</sup>" should have been deleted. This error has been corrected in the HTML and PDF versions of the article. In addition, refs. 36–41 in the original paper have been renumbered as 35–40 and original ref. 35 has been renumbered as ref. 41 throughout the text and in Figure 1.
