Error in Figure

In the original publication [1], there was a mistake in Figure 5D as published, The cell line HGC-7901 should be modified to SGC-7901. The corrected Figure 5D appears below. The authors state that the scientific conclusions are unaffected.

Text Correction

There were errors in the original publication, including The cell line HGC-7901 should be modified to SGC-7901. A correction has been made to Section 2.1, Section 2.3, Section 3.1.2, Caption of Figure 5, Section 3.1.6, Section 3.1.7, and Section Supplementary Materials:
Cell lines SGC-7901 and LO2 were purchased from Cell Bank affiliated with the Chinese Academy of Sciences.
The SGC-7901 cells and LO2 cells were cultured in RMPI-1640 supplemented with 10% FBS at 37 °C in 5% CO2.
Exosomes were isolated by ultracentrifugation from either human gastric cancer cell line SGC-7901 cells or normal human liver cell line LO2.
The expression of typical labeled proteins [41] (transmembrane proteins CD9, CD63 and CD81) of exosomes derived from SGC-7901 was directly verified by Western Blots (WB) (Figure 5D).
Figure 5. (A) The morphology of SGC-7901 cells-derived exosomes revealed by TEM; (B) The morphology of LO2 cells-derived exosomes revealed by TEM; (C) Exosome concentrations and particle sizes distribution of SGC-7901 cells; (D) The Western blots of SGC-7901 cells-derived exosomes.
As previously reported [36], the CD63 expressions of exosomes derived from human gastric cancer cell line SGC-7901 cells were lower than those derived from normal human liver cell line LO2. As shown in Figure 8A, the stronger signals were observed in the group of CD63-low SGC-7901 cells-derived exosomes, while the much weaker signals were observed in the group of CD63-high LO2 cells-derived exosomes with the same concentration of exosomes.
To explore the applicability of this hybrid nanozyme-based aptamer sensor on a clinical approach, SGC-7901-derived exosomes were added to human serum to establish artificial samples for detection.
Table S1: Detection of SGC-7901-derived exosomes in human serum.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
