We present a case report on the successful healing of a Pseudomonas infection wound in a 52-year-old female with morbid obesity, noninsulin dependent diabetes mellitus and a history of tobacco use, who presented with Stage IIIA (T3, N2, Mo) infiltrating ductal carcinoma. The patient received neoadjuvant chemotherapy prior to her bilateral skin-sparing total mastectomies with right axillary sentinel lymphadenectomy. She also had staged reconstruction with temporary breast implants and plans for deep inferior epigastric perforator flaps...

PURPOSE: Infection stones comprise approximately 15% of all urinary tract stones and are induced by infection with urease-positive pathogens. The bacteria within the stone matrix present significant treatment impediments compared to metabolic kidney stones. While much is known about how urinary composition regulates metabolic stone formation, there is a general lack of knowledge around which urinary factors regulate the rate of infection stone formation. Unfortunately, more in-depth research into infection stones is limited by the lack of suitable models for the real-time study of bacterial biofilm formation and stone formation under varying conditions...

Autologous gastrointestinal tissue has remained the gold-standard reconstructive biomaterial in urology for >100 years. Mucus-secreting epithelium is associated with lifelong metabolic and neuromechanical complications when implanted into the urinary tract. Therefore, the availability of biocompatible tissue-engineered biomaterials such as extracellular matrix (ECM) scaffolds may provide an attractive alternative for urologists. ECMs are decellularised, biodegradable membranes that have shown promise for repairing defective urinary tract segments in vitro and in vivo by inducing a host-derived tissue remodelling response after implantation...

Macrophage presence and phenotype are critical determinants of the healing response following injury. Downregulation of the pro-inflammatory macrophage phenotype has been associated with the therapeutic use of bioscaffolds composed of extracellular matrix (ECM), but phenotypic characterization of macrophages has typically been limited to small number of non-specific cell surface markers or expressed proteins. The present study determined the response of both primary murine bone marrow derived macrophages (BMDM) and a transformed human mononuclear cell line (THP-1 cells) to degradation products of two different, commonly used ECM bioscaffolds; urinary bladder matrix (UBM-ECM) and small intestinal submucosa (SIS-ECM)...

The urinary bladder is a central organ of vertebrates and imposes, based on its extreme deformation (volume changes up to several 100%), special requirements on the overall bladder tissue. However, studies focusing on three-dimensional modelling of bladder deformation and bladder function during micturition are rare. Based on three fields, namely, the membrane potential, calcium concentration, and placement, a mechano-electrochemical-coupled, three-dimensional model describing the contractile behaviour of urinary bladder smooth muscle is presented using a strain energy function...

BACKGROUND: Matrix Metalloproteinase 13 (MMP13) is a member of collagenase family and it is involved in the degradation of extracellular matrix and basement membrane protein. It is thought to be associated with tumor invasion and metastasis. Elevated MMP13 expression has been found in carcinoma of the breast, urinary bladder, head and neck and others. It is observed that MMP13 gene is also correlated with radiation response in OSCC (Oral squamous cell carcinoma) cell line based study...

Tissue engineering (TE) approaches using biomaterials have gain important roles in the regeneration of cartilage. This paper describes the production by microfluidics of alginate-based microfibers containing both extracellular matrix (ECM)-derived biomaterials and chondrocytes. As ECM components gelatin or decellularized urinary bladder matrix (UBM) were investigated. The effectiveness of the composite microfibers has been tested to modulate the behavior and redifferentiation of dedifferentiated chondrocytes...

BACKGROUND: Due to the multilineage differentiation ability and paracrine role of adipose-derived stem cells (ASCs) for bladder defect repair, various scaffolds have been applied in combination with ASCs to promote bladder regeneration and restore bladder function. However, the low survival rate of ASCs and the difficulty of promoting bladder functional recovery are still unsolved. To explore these problems, we investigated the feasibility of a novel scaffold seeded with ASCs in a rat model of bladder augmentation...

The biggest challenge of designing and implementing an in vitro study is developing a microenvironment that most closely represents the interactions observed in vivo. Decellularization of tissues and organs has been shown to be an effective method for the removal of potentially immunogenic constituents while preserving essential growth factors and extracellular matrix (ECM ) proteins necessary for proper cell function. Enzymatic digestion of decellularized tissues allows these tissue-specific components to be reconstituted into bioactive hydrogels through a physical crosslinking of collagen...

Urinary bladder matrix (UBM) is used clinically for management of wounds and reinforcement of surgical soft tissue repair, among other applications. UBM consists of the lamina propria and basal lamina of the porcine urinary bladder, and is decellularized as part of the process to manufacture the medical device. UBM is composed mainly of Collagen I, but also contains a wide variety of fibrillar and basement membrane collagens, glycoproteins, proteoglycans and ECM-associated factors. Upon application of the biomaterial in a traumatic or non-traumatic setting in a mouse model, there is a cascade of immune cells that respond to the damaged tissue and biomaterial...

The early macrophage response to biomaterials has been shown to be a critical and predictive determinant of downstream outcomes. When properly prepared, bioscaffolds composed of mammalian extracellular matrix (ECM) have been shown to promote a transition in macrophage behavior from a proinflammatory to a regulatory/anti-inflammatory phenotype, which in turn has been associated with constructive and functional tissue repair. The mechanism by which ECM bioscaffolds promote this phenotypic transition, however, is poorly understood...

Extracellular matrices of xenogeneic origin have been extensively used for biomedical applications, despite the possibility of heterogeneity in structure. Surface modification of biologically derived biomaterials using nanoparticles is an emerging strategy for improving topographical homogeneity when employing these scaffolds for sophisticated tissue engineering applications. Recently, as a tissue engineering scaffold, cholecyst derived extracellular matrix (C-ECM) has been shown to have several advantages over extracellular matrices derived from other organs such as jejunum and urinary bladder...

Spinal cord injury (SCI) is often accompanied by reduced bladder compliance, which contributes to adverse conditions including urinary tract infections and vesicoureteral reflux. Reduced compliance is, in part, attributed to extensive remodeling of the bladder wall, including the extracellular matrix (ECM). Here, we tested the hypothesis that blockade of matrix metalloproteinases (MMPs), known for their ability to remodel the ECM, improves bladder compliance in dogs with SCI. We first evaluated dogs with naturally occurring SCIs resulting from intervertebral disc herniation (IVDH)...

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)...

Extracellular matrix (ECM) hydrogels prepared by tissue decellularization have been reported as natural injectable materials suitable for neural tissue repair. In this study, we prepared ECM hydrogel derived from human umbilical cord (UC) and evaluated its composition and mechanical and biological properties in comparison with the previously described ECM hydrogels derived from porcine urinary bladder (UB), brain, and spinal cord. The ECM hydrogels did not differ from each other in the concentration of collagen, while the highest content of glycosaminoglycans as well as the shortest gelation time was found for UC-ECM...

Central nervous system neurons often degenerate after trauma due to the inflammatory innate immune response to injury, which can lead to neuronal cell death, scarring, and permanently lost neurologic function. Extracellular matrix bioscaffolds, derived by decellularizing healthy tissues, have been widely used in both preclinical and clinical studies to promote positive tissue remodeling, including neurogenesis, in numerous tissues, with extracellular matrix from homologous tissues often inducing more positive responses...

BACKGROUND AND OBJECTIVES: Rectal prolapse is often repaired laparoscopically, frequently with the use of reinforcement material. Both synthetic and biologically derived materials reduce recurrence rate compared to primary suture repair. Synthetic mesh introduces potential complications such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for reinforcement of rectal prolapse repair with the potential to improve durability without risks of synthetic materials...
