The effects of three weeks of hWJ-MSCs-CM treatment (500 µL per rat, i.p.) on serum activity of AST (A), ALT (B), ALP (C), LDH (D) enzymes, and total bilirubin (E) in rats with DM. Data are expressed as mean ± SEM (n = 10). ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, and ^****P < 0.0001 represent significant differences between experimental groups. DM = Diabetic Mellitus; hWJ-MSCs-CM = Conditioned media derived from human Wharton’s jelly mesenchymal stem cells; AST = aspartate aminotransferase; ALT = alanine aminotransferase; ALP = alkaline phosphatase; LDH = lactate dehydrogenase
