TRIM29 and ulcer disease: Figure 6(k) shows the quantitative results of the density of protein western blot bands using ImageQuant TL software. Finally, we also performed immunohistochemical testing on gastric tissues. The results showed that in the Sham group, Trim29 was expressed throughout the gastric lamina propria. In the Model group, only a small amount of Trim29 was expressed at the edge of the ulcer, while MSC and MSC-CM groups significantly increased Trim29 expression (Figures 6(l) and 6(m)).
