Autologous SVF Therapy for Type 2 Diabetes

Type 2 Diabetes Mellitus (T2DM) is a progressive metabolic disorder characterized by insulin resistance and beta-cell dysfunction. Current therapeutic approaches primarily aim to improve insulin sensitivity and glycemic control but do not restore pancreatic beta-cell function or incretin signaling.

The duodenum plays a central role in metabolic signaling and insulin sensitivity regulation. Emerging evidence suggests that gastrointestinal mucosal modulation may improve glycemic control.

Adipose-derived mesenchymal stem cells (ADSCs), obtained from stromal vascular fraction (SVF), have demonstrated immunomodulatory and regenerative properties. The One-STEP™ selective tissue engineering photostimulation technique (1210-nm diode laser) enables preservation of adipocytes and ADSCs without enzymatic digestion, maintaining high cell viability and surface marker expression.

In this study, 40 mL of abdominal subcutaneous adipose tissue will be harvested using laser-assisted photochemical stimulation (Medilaser S 1210 nm). The lipoaspirate will undergo double centrifugation (800g and 700g) to isolate SVF without collagenase. The resulting pellet will be injected into the duodenal submucosa during the same procedure.

Participants will be monitored for six months with metabolic and quality of life assessments.
