Stromal vascular fraction-induced angiogenesis

Stromal vascular fraction (SVF)—a heterogeneous cell mixture isolated from adipose tissue—contains stem cells, endothelial progenitor cells, pericytes, fibroblasts, and immune cells. When embedded within tissue scaffolds or injected into injury sites, these cells promote angiogenesis chiefly by secreting pro-angiogenic growth factors like vascular endothelial growth factor (VEGF) and cytokines that stimulate the migration, proliferation, and assembly of new blood vessels. This mechanism is under active investigation and clinical development for enhancing tissue regeneration in ischemic conditions, wound healing, and other regenerative medicine contexts. SVF-based strategies are cell therapy methods, not single-molecule targets, with notable challenges including biological variability, contamination, and risks associated with stem cell therapy such as unwanted immune or neoplastic responses[1][2][3][4][5].
