Could Stem Cells Heal Chronic Wounds?
In a recent Genes & Diseases review, a CBC Catalyst Team of Guillermo Ameer, NU, Tong-Chuan He and Russell Reid, UChicago, discusses the applicability of stems cells in treating chronic skin wounds
Congratulations to a CBC Catalyst team of Guillermo Ameer, NU, Tong-Chuan He and Russell Reid, UChicago, on their recent review published in Genes & Diseases, titled “Stem Cell Therapy for Chronic Skin Wounds in the Era of Personalized Medicine: from Bench to Bedside.”
The three scientists, who are senior authors on the review, acknowledge CBC’s support of their work, received via a 2013 CBC Catalyst Award for the project titled: “Craniofacial Tissue Engineering with Citric-Acid Based Nanocomposite Scaffolds.”
The review addresses the current state of the therapies used in chronic wound healing pointing out that the presently-used methods are insufficient from both patient and economic viewpoints. They propose using stem cells to address the deficiencies and to hopefully improve therapies outcomes. The cellular and molecular mechanisms of wound healing and of the role that the stem cells play in signaling and recruitment to the wound site of fibroblasts and other factors that speed up the damaged tissue repair are discussed in detail. Finally, the initial results of clinical trials that rely on utilizing stems cells in healing chronic skin wounds are presented.
Guillermo Ameer, DSc, is the Daniel Hale Williams Professor of Biomedical Engineering, Professor of Surgery, and Director of the Center for Advanced Regenerative Engineering, NU. Tong-Chuan He, MD, PhD, and Russell R. Reid, MD, PhD, work at the Department of Surgery, UChicago. Dr. He is Associate Professor of Surgery, and Associate Professor of Orthopedic Surgery and Rehabilitation Medicine, whereas Dr. Reid is Professor of Surgery, specializing in Pediatric Plastic & Reconstructive Surgery, and Bernard Sarnat Scholar of Craniofacial Research.
Additional ties of the three CBC Catalyst team members to the Chicago Biomedical Consortium as well as related articles addressing their work are listed below.

With the significant financial burden of chronic cutaneous wounds on the healthcare system, not to the personal burden mention on those individuals afflicted, it has become increasingly essential to improve our clinical treatments. This requires the translation of the most recent benchtop approaches to clinical wound repair as our current treatment modalities have proven insufficient. The most promising potential treatment options rely on stem cell-based therapies. Stem cell proliferation and signaling play crucial roles in every phase of the wound healing process and chronic wounds are often associated with impaired stem cell function. Clinical approaches involving stem cells could thus be utilized in some cases to improve a body’s inhibited healing capacity. We aim to present the laboratory research behind the mechanisms and effects of this technology as well as current clinical trials which showcase their therapeutic potential. Given the current problems and complications presented by chronic wounds, we hope to show that developing the clinical applications of stem cell therapies is the rational next step in improving wound care.
