In the published article, there was an error in Figures 4A, E as published. We accidently applied mismatched images to Figures 4A, E. The corrected Figure 4 appears below.
FIGURE 4.
Beige adipocyte formation was associated with early angiogenesis and the production of VEGF-A and FGF21. (A) Angiogenesis of fat grafts was superior at day 14 than day 7, 30, and 90. (B) Quantification of CD31-positive cells at different time points. (C, D) Expression levels of angiogenic genes, VEGF-A and FGF21. (E) Angiogenesis in the fat grafts 2 weeks and 10 weeks after transplantation, identified using immunohistochemical staining for CD31. (F) Number of CD31+ vessels at week 2 and week 10. (G) Expression of the Vegfa and Fgf21 genes in the fat grafts at week 2, measured using quantitative RT-PCR. (H) Expression of HIF1-α associated with hypoxia at week 2 and week 10. (*p < 0.05; **p < 0.01; ****p < 0.0001). Scale bar = 50 μm.
