Mesenchymal stem cells to treat diabetic neuropathy: a long and strenuous way from bench to the clinic

View Article: PubMed Central - PubMed

ABSTRACT

As one of the most common complications of diabetes, diabetic neuropathy often causes foot ulcers and even limb amputations. Inspite of continuous development in antidiabetic drugs, there is still no efficient therapy to cure diabetic neuropathy. Diabetic neuropathy shows declined vascularity in peripheral nerves and lack of angiogenic and neurotrophic factors. Mesenchymal stem cells (MSCs) have been indicated as a novel emerging regenerative therapy for diabetic neuropathy because of their multipotency. We will briefly review the pathogenesis of diabetic neuropathy, characteristic of MSCs, effects of MSC therapies for diabetic neuropathy and its related mechanisms. In order to treat diabetic neuropathy, neurotrophic or angiogenic factors in the form of protein or gene therapy are delivered to diabetic neuropathy, but therapeutic efficiencies are very modest if not ineffective. MSC treatment reverses manifestations of diabetic neuropathy. MSCs have an important role to repair tissue and to lower blood glucose level. MSCs even paracrinely secrete neurotrophic factors, angiogenic factors, cytokines, and immunomodulatory substances to ameliorate diabetic neuropathy. There are still several challenges in the clinical translation of MSC therapy, such as safety, optimal dose of administration, optimal mode of cell delivery, issues of MSC heterogeneity, clinically meaningful engraftment, autologous or allogeneic approach, challenges with cell manufacture, and further mechanisms.

Mentions: The application of the use of MSCs to treat DN has been extensively investigated in preclinical animal models in recent years and the majority of reports indicate positive effects on DN. Despite this, there are significant challenges to be met for the successful clinical translation of these studies from animal model to the patient’s bedside. Although MSC therapies protect from neurodegeneration and promote neuroregeneration, there appear to be many obstacles to be overcome for clinical applications (Figure 3). These are: (1) optimal dose of administration owing to limited survival of transplanted cells, (2) safety for risk of tumor formation, (3) route of transplantation for effectiveness, (4) autologous or allogeneic approach, impairing potency of MSCs from diabetes, (5) further mechanisms, and (6) clinical end points for the efficacy of MSC therapy.
