GDM-hAMSCs exhibit a specific pro-angiogenic expression profile. A Heatmap comparing angiogenic gene expression between the GDM and NGT groups (N = 14 in each). Data are represented as log₂ (fold change). Differences assessed by Mann–Whitney U test. B Western blot analysis of FGFR2, TGFBR1, PAI-1 and VEGFA protein expression. Representative image and densitometry analysis (arbitrary units, N = 9 each group). Data are normalized to the mean of the controls of each experiment and are shown as mean ± SEM. Differences assessed by Student’s t test. *P < 0.05; **P < 0.01; ***P < 0.001
