CXCR4 and diabetes mellitus: These include factors related to migration, survival, inflammatory function and angiogenesis, such as C-X-C chemokine receptor type 4 (CXCR4), CXCR7, SDF-1, chemokine (C-C motif) ligand 2 (CCL2) and angiopoietin-like 4 protein (ANGPTL4), which were significantly downregulated in hASCs from patients with diabetes (d-hASCs) in comparison with healthy donors [132,157,158,159].
