The article (1) titled “Mesenchymal stem cells alleviate aging in vitro and in vivo” (doi: 10.21037/atm-22-1206) unfortunately contains errors in Figure 3. Two images of Figure 3A selected to represent the group of aged mice and the aged mice treated with bone marrow-derived mesenchymal stem cell (BMSC) were duplicated accidentally while the figure legend remains intact.
Figure 3A of the original article:
The correct version of Figure 3, containing the correct data for the aged and BMSC in Figure 3A, is shown below:
Figure 3.
Effect of BMSCs on aged mice. (A) Images of control, aged mice and aged mice treated with BMSC. (B) Survival rates of aged mice with and without BMSCs treatment. BMSCs were given at the age of 20 months old and were observed up to 4 months (n=15). (C) Urine spot test of three groups of mice within 3 hours. (D) Statistical analysis of the number of urinary spots in three groups of mice (n=4–6). Data were expressed as mean ± SE and analyzed using log-rank (Mantel-Cox) test for survival rate and one-way ANOVA for the number of void spot count. **, P<0.01. BMSCs, bone marrow-derived mesenchymal stem cells; SE, standard error; ANOVA, analysis of variance.
The authors regretted the errors and confirmed that these errors did not significantly affect either the results or the conclusions of the paper.
