Background: Diabetic kidney disease (DKD) is one of the most significant public health burdens worldwide. This study explored the renal protections of combined adipose-derived mesenchymal stem cells (ADMSCs) and empagliflozin (EMPA) in DKD rats. Methods: Adult-male-SD rats were equally allocated into group 1 (sham-operated-control), group 2 (DKD), group 3 (DKD + EMPA/20 mg/kg/day since day-14 after CKD-induction), group 4 [DKD + ADMSCs (6.0 × 105/intrarenal-arterial-injection/post-day-28, followed by 1.2 × 106/intravenous injection post-days 35 and 42 after CKD-induction, i.e., defined as repeated administration)] and group 5 (DKD + ADMSCs + EMPA) and kidney was harvested post-day-60 CKD-induction. Results: The result showed that the blood sugar and circulatory levels of BUN/creatinine and the ratio of urine protein/creatinine at day 60 were greatly increased in group 2 as compared the SC (i.e., group 1), significantly increased in groups 3 and 4 than in groups 5, but these parameters showed the similar manner in groups 3 and 4, except for blood sugar that was significantly lower in group 3 than in group 4 (all p < 0.0001). The protein levels of inflammation (NF-κB/FNF-α/MMP-9)/oxidative-stress (NOX-1/NOX-2/oxidized protein/p22-phox)/apoptosis (cleaved-caspase-3/cleaved-PARP/mitochondrial-Bax)/fibrosis (TGF-β/Smad 3)/mitochondrial/DNA-damaged (p-DRP1/γ-H2AX) biomarkers revealed a similar manner of creatinine level among the groups (all p < 0.0001). Kidney injury score/fibrotic area/oxidative-stress score (8-OHdG) and cellular levels of kidney-damaged biomarkers (KIM-1/γ-H2AX) showed a unanimous manner. In contrast, the cellular expressions of podocyte components (ZO-1/synaptopodin) revealed an antithetical manner of creatinine among the groups (all p < 0.0001). Conclusion: Combined ADMSCs-EMPA was superior to just one therapy for protecting kidney function and ultra-structural integrity in DKD rodents.
