Efficacy of Adipose Tissue Derived Stem Cells for the Treatment of Diabetic Foot Ulcers

December 30, 2024 updated by: Azra Mehmood, University of the Punjab

Autologous Adipose Tissue Derived Stromal Vascular Fraction Versus Cultured Adipose Derived Stem Cells for the Treatment of Chronic Diabetic Wounds

The aim of this study is to evaluate the therapeutic efficacy of uncultured adipose derived stromal vascular fraction (SVF) and cultured adipose derived stem cells (ASCs) both supplemented with platelet rich plasma (PRP) to treat chronic diabetic foot ulcers. It will increase the pragmatic potential of both types of cells as PRP is rich in survival and chemotactic factors. Moreover, the autologous nature of the proposed study will ensure safety of its use in diabetic patients and will unveil the more effective therapeutic option for treatment of foot ulcer wounds.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Under local or general anesthesia, autologous fat will be harvested by using a manual aspiration or syringe-assisted technique. SVF and ASCs isolation from autologous lipoaspirates will be done by enzymatic digestion method (collagenase Type-1 solution for 45 minutes at 37°C). Cell quality assessment will be done prior to transplantation by trypan blue exclusion assay and total populations and fractions of cells identified by immunocytochemistry / flow cytometry. PRP will be derived by centrifugation from 50-100ml blood collected in anticoagulant carrying bag, from patient at the day of transplantation. The injection volume will depend on the wound area of each patient. 2 million cells/ 0.5 ml PRP will be mixed, transferred to 1 cc syringes and injected / cm2 intradermally at the border zone & inside of wound surface bed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
