As an alternative to polypropylene mesh, we explored an extracellular matrix (ECM) bioscaffold derived from urinary bladder matrix (MatriStem™) in the repair of vaginal prolapse. We aimed to restore disrupted vaginal support simulating application via transvaginal and transabdominal approaches in a macaque model focusing on the impact on vaginal structure, function, and the host immune response. In 16 macaques, after laparotomy, the uterosacral ligaments and paravaginal attachments to pelvic side wall were completely transected (IACUC# 13081928)...

Objective: Burn injuries remain a large financial burden on the healthcare system. According to CDC statistics (2010), nonfatal and hospitalized burns in the U.S. cost $1.8 billion for an annual incidence of ∼486,000 cases. To date, no technique proves to be the ideal therapy of deep partial-thickness burns. In this study, we review a trial usage of ACell (ACell, Inc.) wound matrix on deep partial-thickness burns. Approach: Burn patients were admitted through the Vanderbilt Emergency Department. Three were consented to receive ACell therapy...

Volumetric muscle loss (VML) results in irrecoverable loss of muscle tissue making its repair challenging. VML repair with acellular extracellular matrix (ECM) scaffolds devoid of exogenous cells has shown improved muscle function, but limited de novo muscle fiber regeneration. On the other hand, studies using minced autologous and free autologous muscle grafts have reported appreciable muscle regeneration. This raises the fundamental question whether an acellular ECM scaffold can orchestrate the spatiotemporal cellular events necessary for appreciable muscle fiber regeneration...

Primary cardiac sarcomas are rare and carry a grave prognosis. Improved survival requires a complete margin negative resection of the tumor. These surgical resections are often large and complex, requiring extensive reconstructive procedures. The appropriate material for cardiac reconstruction is not known. We have used glutaraldehyde-fixed bovine pericardium in our early series but have recently employed the MatriStem(®) Surgical Matrix PSMX membrane (ACell(®), Inc.; Columbia, MD), a unique proprietary urinary bladder matrix derived from porcine urinary bladder with the potential for viability and tissue ingrowth...

BACKGROUND: Extracellular matrix is used in various applications. We present our preliminary experience using a new device that consists of a porcine extracellular matrix with an epithelial basement membrane (MatriStem(®), ACell, Inc. Columbia, MD, USA) for adolescent pilonidal disease. METHODS: A retrospective review of four patients with pilonidal disease was undertaken. Three occurred in the gluteal cleft, and the fourth in the umbilicus. In the first patient, the wound deficit was filled with lyophilized MicroMatrix powder and a sheet of Multilayer Wound Matrix was placed to cover the wound...

BACKGROUND: Septal ulceration is a mucositis involving the mucous membranes of the nasal septum. Patients often complain of nasal irritation, crusting, and epistaxis. Presently, there is no gold standard for the treatment of septal ulcerations. Currently described therapies include local debridement, septal dermoplasty, septal flap reconstruction, and cadaveric dermal graft repair; however, no therapy has demonstrated a consistent improvement of symptoms. We present a novel approach for the treatment of chronic septal ulceration, using an extracellular matrix scaffold (MatriStem® Wound Care Matrix, ACell, Inc...

Malignant cardiac tumors typically have a grave prognosis; their resection with negative margins is optimal. We present the case of a 21-year-old woman in whom we surgically resected a primary cardiac sarcoma and reconstructed the right atrium with use of a porcine urinary bladder membrane-the MatriStem(®) Surgical Matrix PSMX. The patient recovered uneventfully. Six months postoperatively, the right atrial wall had retained its integrity. In addition to our patient's case, we discuss the benefits of using the MatriStem membrane in cardiac reconstruction...

Extracellular matrix (ECM) derived scaffolds continue to be investigated for the treatment of volumetric muscle loss (VML) injuries. Clinically, ECM scaffolds have been used for lower extremity VML repair; in particular, MatriStem™, a porcine urinary bladder matrix (UBM), has shown improved functional outcomes and vascularization, but limited myogenesis. However, efficacy of the scaffold for the repair of traumatic muscle injuries has not been examined systematically. In this study, we demonstrate that the porcine UBM scaffold when used to repair a rodent gastrocnemius musculotendinous junction (MTJ) and tibialis anterior (TA) VML injury does not support muscle tissue regeneration...

Anal fistulas are difficult to treat because they are often recalcitrant to medical therapies and surgical treatment may lead to significant morbidities. A recent novel biologically derived graft from porcine urinary bladder (MatriStem(TM)) has shown great promise in experimental studies of tissue regeneration in diverse tissues. The objectives of this study were to evaluate the safety and short-term efficacy of MatriStem for treatment of anal fistulas. This was a retrospective study of patients treated from January 3, 2012 to March 3, 2014 at the University of Pittsburgh Medical Center...

BACKGROUND: Esophagojejunal (EJ) anastomotic leaks after total gastrectomy (TG) for malignancy lead to significant morbidity and mortality, thus affecting long-term survival. Preclinical and clinical trials have shown promise in utilizing degradable extracellular matrix (ECM) scaffolds in buttressing anastomoses. We describe our experience buttressing the EJ anastomosis after TG with a ECM scaffold. METHODS: From February 2012 to January 2014, a total of 37 consecutive patients underwent TG buttressing of the EJ anastomosis with the degradable ECM scaffold composed of a porcine urinary bladder called MatriStem (ACell Inc...

Randall's plaque (RP) deposits seem to be consistent among the most common type of kidney stone formers, idiopathic calcium oxalate stone formers. This group forms calcium oxalate renal stones without any systemic symptoms, which contributes to the difficulty of understanding and treating this painful and recurring disease. Thus, the development of an in vitro model system to study idiopathic nephrolithiasis, beginning with RP pathogenesis, can help in identifying how plaques and subsequently stones form. One main theory of RP formation is that calcium phosphate deposits initially form in the basement membrane of the thin loops of Henle, which then fuse and spread into the interstitial tissue, and ultimately make their way across the urothelium, where upon exposure to the urine, the mineralized tissue serves as a nidus for overgrowth with calcium oxalate into a stone...

Complex open pilonidal wounds represent a challenging wound healing problem. Nine cases of complex open pilonidal wounds are described. Each of them was treated at the time of primary wide excision with placement of xenograft extracellular matrix material derived from urinary bladder (MatriStem, ACell Corporation). The patients left the xenograft material and dressings intact and returned to our clinic at weekly intervals for inspection of the wounds. All of the cases of complex open pilonidal wounds healed without infection and without requiring re-operation...

Local and regional flap failure can be a major complication in head and neck surgery, which continue to be prevalent for a number of reasons including poor flap design, improper surgical technique, and poor tissue vascularity. Dealing with these failures can be quite difficult. Surgical debridement, flap revisions, and complex wound regimens are necessitated to reestablish appropriate tissue coverage. Traditional use of wet to dry dressing to enable proper wound granulation and possible closure with additional flaps or skin grafts is a laborious process...

Chronic wounds in previously radiated tissue are challenging to treat. In this article, the authors describe 3 such wounds that failed to heal despite multiple treatments with traditional wound healing methods. Treatment with porcine urinary bladder matrix, an extracellular matrix material, was initiated to facilitate epithelialization and promote wound healing. MatriStem powder (ACell, Inc, Columbia, Maryland), MatriStem (ACell, Inc) sheet, and DuoDerm (ConvaTec, Skillman, New Jersey) were applied biweekly and resulted in complete wound closure within 3 weeks of initial application for all 3 cases...
