A newly synthesized nanoplatform of hyaluronic acid and chitosan nanoparticles (HA/CNPs) was applied to improve the therapeutic efficacy and protection of bone marrow mesenchymal stem cells (BM-MSCs) against cisplatin (CDDP)-induced nephrotoxicity in rats. CDDP administration causes significant increases in levels of serum creatinine (SCr), urea, and KIM-1 coupled with significant albumin level falls, as indicative of acute renal dysfunction. Moreover, the level of the antioxidant enzyme (GSH) was significantly decreased, while the levels of lipid peroxidation (MDA) and inflammatory (IL-6) and apoptotic (caspase-3) markers were significantly increased, indicating a decline in the kidney's antioxidant defense and increased inflammation. In contrast, when rats were pre-treated with either MSCs or MSCs-HA/CNPs before receiving CDDP, the levels of SCr, urea, KIM-1, MDA, IL-6, and caspase-3 were significantly decreased with simultaneous significant rises in GSH and albumin, impelling a great improvement in the antioxidant and anti-inflammatory defenses of the kidney as well as its functions. Intriguingly, MSCs-HA/CNPs were more effective against caspase-3 than MSCs alone, revealing the high anti-apoptotic capability of HA/CNPs. This finding suggests that HA/CNPs could effectively protect MSCs from oxidative stress and apoptosis and thus increase their stability and longevity.
