Systemic Biochemical Signature and Functional Quality Index of Calcaneal Bone Marrow Aspirate in Adults Undergoing Foot or Ankle Surgery

This observational prospective cohort study will evaluate whether routine blood tests are associated with the functional quality of calcaneal bone marrow aspirate mesenchymal stem cells in adults undergoing clinically indicated foot or ankle surgery at a university hospital in Brazil. Participants aged 40 to 80 years, with or without comorbidities, including type 2 diabetes mellitus and, when present, active Wagner grade 2-4 diabetic foot ulcers, will be eligible for inclusion. Before surgery, participants will undergo routine blood tests, including complete blood count, glucose and lipid profile, mineral-renal markers, and tissue damage markers. During the clinically indicated surgery, calcaneal bone marrow aspirate will be collected from the same operative field. Mesenchymal stem cells will be isolated and evaluated in the laboratory for clonogenic capacity, osteogenic and adipogenic differentiation, cellular senescence, and secretion of inflammatory and anti-inflammatory cytokines. A composite Functional Quality Index of Bone Marrow Aspirate (IQF-BMA) will be constructed from routine laboratory markers to characterize inflammatory, metabolic, mineral-renal, and tissue-damage burden. The primary objective is to examine the association between the IQF-BMA and mesenchymal stem cell functional outcomes, particularly clonogenic capacity. This exploratory study will not be used to guide individual treatment decisions.

Randomized Evaluation of Nonhealing Diabetic Foot Ulcers With Exclusive Wound Therapy

The goal of this study is to determine the between-arm difference in the proportion of subjects achieving complete closure of nonhealing diabetic foot ulcers with multiple CAMPs plus SOC versus matched controls over 12 weeks using a modified platform trial design.

A Multicenter, Prospective, Controlled Clinical Trial Evaluating the Efficacy of a Single Layer Placental-based Allograft and Standard of Care in the Management of Nonhealing Diabetic Foot Ulcers

A multicenter, prospective, controlled clinical trial evaluating the efficacy of a single layer placental-based allograft and standard of care in the management of nonhealing diabetic foot ulcers.

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

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.

Modified Platform Trial Evaluating PpLHACM and SOC Versus SOC Alone in the Treatment of Nonhealing DFUs

This study will evaluate two human amnion/chorion membrane (ppLHACM) products and Standard of Care (SOC) versus SOC alone in the closure of nonhealing diabetic foot ulcers (DFUs).
