Professor Widgerow completed his undergraduate and post-graduate studies at the University of the Witwatersrand, South Africa. He was the top surgical graduate at the University of Witwatersrand in 1989. He has held various positions in numerous academic and professional associations including that of President of the Association of Plastic and Reconstructive surgery of Southern Africa (APRSSA). He is a Fellow of the American College of Surgeons and was appointed Honorary Professor by the Senate of Wits University in 1999. He is author of over 110 plastic surgical related publications and 2 books. He is currently editor-in-chief of Wound Healing Southern Africa. He was also the founder and medical director of 11 wound clinics in South Africa. His current fields of interest are translational basic science research, medical device innovations, tissue engineering and wound healing.

After 20 years in private plastic surgical practice in South Africa, Prof Widgerow relocated to Irvine California in Dec 2009 to pursue his interests in research, medical device innovations and wound care, but he still plays an active role in academic medicine world-wide. In August 2012 he joined the University of California Irvine Plastic Surgery Division as Clinical Professor and Director Center for Tissue Engineering. He has redesigned and introduced major Research projects to the TERM Lab and has entered submissions on multiple Grant proposals. He has recruited a team of 20 researchers and runs a vibrant, dynamic research facility at UCIMC
Research Abstract
1. Micro/nanobubbles and wound healing

Micro/nanobubbles (MNBs) offer a new technology for creating oxygen-enriched fluids. Bubbles are gas-containing cavities in an aqueous solution. Microbubbles have a diameter between 1 and 100 µm, and nanobubbles - less than 1 µm. Fluids can be saturated with various gases, e.g. oxygen, using MNB technology with our designed device. This results in an excellent vehicle for external oxygen delivery to tissues. Nanobubbles have several unique properties. They can form freely and remain in an aqueous solution for extended periods of time with the capacity to act as a reservoir and store oxygen; thus, interest in micro/nanobubbles is growing.

Chronic non-healing wounds constitute a major health problem particularly in the elderly population. Local tissue hypoxia, related to health problems such as diabetes, venous stasis and peripheral vascular disease, is a common feature accompanying all types of chronic wounds with ischemia reperfusion cycles contributing significantly to tissue damage. Oxygen delivery has been identified as a major factor affecting wound healing and it is accepted that limited oxygenation can lead to a chronic nonhealing ulcer. Maintaining an appropriate level of oxygen in these wounds continues to be a challenge.

We hypothesize that MNB technology can be successfully used for transporting oxygen to tissues in state of hypoxia. Potentially, the stability of MNBs can allow for the production of off-the-shelf solutions with a known concentration of oxygen. When used to irrigate wounds, such solutions would be expected to have the following effects: (1) to increase wound oxygen tension; (2) to provide debridement and (3) to subsequently promote healing.

2. Mechanical Stress and the regenerative cell

Diabetes constitutes a global emergency and the diabetic foot ulcer (DFU), a complication of the disease, is the leading cause of nontraumatic lower limb amputations. Current methods for DFU prevention are primarily through education and physical offloading, while treatment after ulcer formation is laden with expense and unpredictable outcomes. Autologous fat grafting enriched with adipose-derived mesenchymal stem cells (MSCs) has tremendous promise for enhanced lipofilling and therefore replacement of the atrophied fat pad for the prevention of DFUs. Additionally, recent mouse and human studies have demonstrated that direct injection of healthy human MSCs can significantly alter the clinical course of the DFU by increasing angiogenesis and improving wound healing. Unfortunately, diabetic patients have fewer endogenous MSCs that exhibit decreased stem cell markers, cellular functioning and ability to proliferate. Recently, our group demonstrated that mechanical stress can be used to induce a ~7.5 fold increase in the universal stem cell marker CD34 as well as statistically significant increases in MSCs, endothelial progenitor cells, and pluripotent Muse cells in healthy adipose tissue. We hypothesize that similar processing can be used to activate the senescent stem cells in diabetic adipose tissue which can then be used for autologous enriched fat graft prevention of DFU development or for the direct injection to heal established DFUs

3. Deconstructing Adipo-induction In Decellularized Adipose Matrix (AAM)

Collaborative partnership with Musculoskeletal Transplant Foundation (MTF) exploring the use of acellular adipose derived matrices in fat generation, wound healing and tissue engineered frameworks
Global hypothesis: Adipogenesis has been demonstrated to occur when unseeded AAM is injected subcutaneously in an area relatively devoid of fat. The sequential cellular and chemokine response to AAM results in a microenvironment that is conducive to adipogenesis. We hypothesize that the AAM provides the necessary stimulus for cellular attraction, attachment, signaling and vasculogenesis that promotes the transformation of acellular extracellular matrix to definitive adipose tissue.
Global aim: To delineate the sequence of events occurring following implantation of AAM to the final process of adipogenesis
Specific individual aims:
• compare adipoinduction of adipose/fascia complex to that of adipose fraction alone
• identify early and late cellular infiltrates
• identify cytokines, adipokines, enzymes (related to macrophage phenotype and lipoproteins)

4. Tissue engineered 3-D ear cartilage construct

Generation of cartilage engineered frameworks using unique adipose derived matrices, chondrocytes and adipose derived stem cells. Collaborative effort with MTF, RapidTech BME, UCI (3-D printing) and Lakey laboratory

Tissue engineering technologies offer new approaches in the field of external ear reconstruction. In this treatment setting, attempts have been made to use the patients’ own chondrocytes isolated from the remnants of auricular cartilage and cultured in the laboratory with the aim of creating bioengineered cartilage matrices. However, cartilage engineering has many challenges, starting with the difficulty in culturing sufficient chondrocytes. Small pieces of cartilage like that obtained from microtia patients tend to give low yields of chondrogenic cells. Moreover, adequately expanding these cells is challenging as chondrocytes tend to lose their specific properties and acquire a fibroblast-like phenotype in monolayer cultures. To overcome these difficulties, research in the field of cartilage engineering has been conducted in two main directions:
(1) the use of co-cultures to expand the number of chondrogenic cells
(2) culturing on three-dimensional (3D) scaffolds that resemble the native environment of chondrocytes inside the body.
