Abstract (original English)

Pericytes (PCs), a heterogeneous population of perivascular supporting cells, are critical regulators of vascular stability, angiogenesis, and blood-tissue barrier integrity. Increasing evidence highlights their active role in the pathophysiology of diabetic microangiopathies, including those affecting the retina, kidney, brain, heart, and peripheral nerves. In diabetes, hyperglycemia-induced PC dysfunction is a major contributor to vascular degeneration, impaired tissue repair, and disease progression across multiple organs. Pericytes also share many characteristics with mesenchymal stem cells (MSCs). They exhibit regenerative capacity, immunomodulatory activities, and multipotent capacities. This review explores the emerging role of PCs as tissue resident MSCs, emphasizing their pathophysiological involvement in diabetes complications, and their potential for utilization in regenerative medicine. We also discuss advances in PC-based therapies, tissue engineering strategies, and clinical applications. Thus, PCs are positioned as promising targets for therapeutic intervention and vascular tissue regeneration.
