Following the publication of the original article [1], the authors identified some errors.

1: The authors noticed that the figure legend of Fig. 4 should be added with positive HuNu staining (red) to provide additional clarification. The updated figure legend of Fig. 4 is provided in this correction.

2: Fig. 7D was mistakenly duplicated from 7C. The correct Fig. 7D is provided in this correction.

3: Fig. 8C was mistakenly duplicated from 8B. The correct Fig. 8C is provided in this correction.

4: The affiliation of the corresponding author is not accurate. The footnote on the first page should be changed to “²Second Department of Elderly Respiratory, Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences, Guangdong Provincial Geriatrics Institute, Guangzhou, 510,080, China.”

It has been corrected after the authors double checked the original data. The results and conclusions concluded in this paper are still valid.

Legend for figure 4:

Fig. 4 Engraftment of SHED around the fistula and in the lung. A Surviving SHED (positive HuNu staining (red)) after transplantation around the fistula. SHED were found in both the I‑SHED group and the L‑SHED group. No SHED were observed in the I‑PBS and L‑PBS groups. B Surviving SHED (positive HuNu staining (red)) after transplantation in the lung. SHED were found in the I‑SHED group. However, no transplanted SHED were seen in the other groups.

TLR4 expression levels in the lungs using immunohistochemistry and western blotting. A Immunohistochemical staining of TLR4 in the lungs. B Western blotting of TLR4. C Quantification of TLR4 staining in the lungs. D Relative expression of TLR4 standardized to GAPDH. (n = 3/group; *P < 0.05, **P < 0.01, and ***P < 0.001 compared by one-way ANOVA with Turkey’s post-hoc tests)

C Relative expression of MYD88 standardized to GAPDH. (n = 3/group; *P < 0.05, **P < 0.01, and ***P < 0.001 compared by one-way ANOVA with Turkey’s post-hoc tests)
