Autologous SVF Therapy for Type 2 Diabetes (LASER-DM2 Tria)

March 17, 2026 updated by: Kaiser Clinic and Hospital

Evaluation of Autologous Adipose-Derived Stromal Vascular Fraction Obtained by 1210-nm Laser Photostimulation for the Treatment of Type 2 Diabetes Mellitus

This prospective clinical study aims to evaluate the safety and efficacy of autologous adipose-derived stromal vascular fraction (SVF), enriched with mesenchymal stem cells (ADSCs), for the treatment of Type 2 Diabetes Mellitus (T2DM).

Adipose tissue will be harvested using a 1210-nm diode laser-assisted selective photochemical stimulation technique (One-STEP™ method), followed by centrifugation without enzymatic digestion. The isolated SVF will be injected endoluminally into the duodenal submucosa during the same surgical procedure.

Five adult patients with T2DM will be followed for six months to assess metabolic control, pancreatic function, and quality of life outcomes.

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Autologous SVF Duodenal Injection
Participants with Type 2 Diabetes Mellitus will undergo abdominal adipose tissue harvesting using a 1210-nm diode laser-assisted selective photochemical stimulation technique (One-STEP™ method). The lipoaspirate will be processed by centrifugation without enzymatic digestion to isolate stromal vascular fraction (SVF) enriched with mesenchymal stem cells. The isolated SVF will be injected into the duodenal submucosa during the same surgical procedure. Participants will be followed for six months to assess metabolic outcomes and safety.
Biological: Autologous Adipose-Derived Stromal Vascular Fraction (SVF)
Autologous adipose tissue will be harvested using a 1210-nm diode laser-assisted liposuction technique (One-STEP™). The lipoaspirate will undergo double centrifugation without collagenase digestion to isolate stromal vascular fraction enriched with mesenchymal stem cells. The isolated SVF will be immediately injected into the duodenal submucosa during the same operative session.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Fasting Plasma Glucose (mg/dL)
Time Frame: Baseline and 6 months post-procedure
The primary outcome is the change in fasting plasma glucose levels (mg/dL) from baseline to 6 months after autologous stromal vascular fraction (SVF) injection into the duodenal submucosa. Fasting plasma glucose will be measured after an overnight fast of at least 8 hours.
Baseline and 6 months post-procedure
