Summary
Endothelial progenitor cells (EPCs) show promise for treating diabetic vascular complications. However, diabetic EPCs are dysfunctional, requiring strategies to improve their function for effective cell therapy.
Area of Science:
- Regenerative Medicine
- Vascular Biology
- Diabetology
Background:
- Diabetic complications like retinopathy impair vascular repair.
- Current therapies for diabetic vascular disease have limitations and side effects.
- Autologous endothelial progenitor cells (EPCs) offer a potential cell-based therapy for revascularization.
Purpose of the Study:
- To review the potential of endothelial progenitor cells (EPCs) for treating diabetic vascular complications.
- To highlight the challenges posed by diabetes to EPC function and the diabetic environment.
- To discuss strategies for improving dysfunctional EPCs for therapeutic use.
Main Methods:
- Literature review focusing on EPC biology in diabetes.
- Analysis of molecular and phenotypic alterations in diabetic EPCs.
- Exploration of novel strategies to enhance EPC function and overcome the diabetic milieu.
Main Results:
- Diabetic patients' EPCs exhibit dysfunction, hindering their therapeutic efficacy.
- The diabetic environment itself presents challenges for autologous EPC transplantation.
- Various strategies are being investigated to optimize EPCs for diabetic patients.
Conclusions:
- Harnessing EPCs for vascular repair in diabetes requires addressing EPC dysfunction and the adverse diabetic environment.
- Further research is needed to identify optimal EPCs and develop effective modification strategies.
- Cell therapy holds promise but necessitates overcoming significant biological hurdles for successful application in diabetic vascular disease.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
