Abstract
Hyperglycemia-induced damage to the glomerular podocyte is thought to be a critical early event in diabetic nephropathy. Interventions that prevent podocyte damage or loss have been shown to have potential for the treatment of diabetic nephropathy. New data show that conditioned medium from adipocyte-derived mesenchymal stem cells has the potential to protect podocytes from high-glucose-induced damage. Furthermore, epidermal growth factor may be the critical ingredient mediating this effect. These data suggest that components of the conditioned medium of mesenchymal stem cells, in addition to the cells themselves, may have potential for the treatment of diseases such as diabetic nephropathy.
