TNF-α and MK2206 attenuate ADM2-improved pro-angiogenic ability of BMSCs. (A,B) Representative images (A) and quantification of tube formation (B) in endothelial cells stimulated with conditioned medium from BMSCs treated with OIM, OIM + ADM2, OIM + ADM2 + TNF-α, OIM + ADM2 + MK2206, and OIM + ADM2 + TNF-α + MK2206. Scale bar: 200 μm. (C–F) Endothelial cell motility in each group was evaluated using the Transwell migration assay (C,D) and the scratch wound assay (E,F). Scale bar: 200 μm. The data were confirmed by one-way analysis of variance (ANOVA) followed by Tukey’s post hoc test from three independently repeated tests and are presented as the means ± SD. *P < 0.05, **P < 0.01.
