Abstract
The absence of effective extracellular matrix to mimic the natural tumor microenvironment remains a significant obstacle in cancer research. Matrigel, abundant in various biological matrix components, is limited in its application due to its high cost. This has prompted researchers to explore alternative matrix substitutes. Here, we have investigated the effects of the extracellular matrix derived from pig small intestinal submucosa (ECM-SIS) in xenograft tumor modeling. Our results showed that the pig-derived ECM-SIS effectively promotes the establishment of xenograft tumor models, with a tumor formation rate comparable to that of Matrigel. Furthermore, we showed that the pig-derived ECM-SIS exhibited lower immune rejection and fewer infiltrating macrophages than Matrigel. Gene sequencing analysis demonstrated only a 0.5% difference in genes between pig-derived ECM-SIS and Matrigel during the process of tumor tissue formation. These differentially expressed genes primarily participate in cellular processes, biological regulation, and metabolic processes. These findings emphasize the potential of pig-derived ECM-SIS as a cost-effective option for tumor modeling in cancer research.

Abstract
Cardiac septal defect is the most prevalent congenital heart disease and is typically treated with open-heart surgery under cardiopulmonary bypass. Since the 1990s, with the advancement of interventional techniques and minimally invasive transthoracic closure techniques, cardiac occluder implantation represented by the Amplazter products has been the preferred treatment option. Currently, most occlusion devices used in clinical settings are primarily composed of Nitinol as the skeleton. Nevertheless, long-term follow-up studies have revealed various complications related to metal skeletons, including hemolysis, thrombus, metal allergy, cardiac erosion, and even severe atrioventricular block. Thus, occlusion devices made of biodegradable materials have become the focus of research. Over the past two decades, several bioabsorbable cardiac occluders for ventricular septal defect and atrial septal defect have been designed and trialed on animals or humans. This review summarizes the research progress of bioabsorbable cardiac occluders, the advantages and disadvantages of different biodegradable polymers used to fabricate occluders, and discusses future research directions concerning the structures and materials of bioabsorbable cardiac occluders.

De Novo Valve Tissue Morphology Following Bioscaffold Mitral Valve Replacement in a Juvenile Non-Human Primate Model. Bioengineering (Basel) 2021; 8:bioengineering8070100. [PMID: 34356207 PMCID: PMC8301182 DOI: 10.3390/bioengineering8070100] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/09/2021] [Accepted: 07/13/2021] [Indexed: 12/04/2022] Open
Abstract
The utility of implanting a bioscaffold mitral valve consisting of porcine small intestinal submucosa (PSIS) in a juvenile baboon model (12 to 14 months old at the time of implant; n = 3) to assess their in vivo tissue remodeling responses was investigated. Our findings demonstrated that the PSIS mitral valve exhibited the robust presence of de novo extracellular matrix (ECM) at all explantation time points (at 3-, 11-, and 20-months). Apart from a significantly lower level of proteoglycans in the implanted valve’s annulus region (p < 0.05) at 3 months compared to the 11- and 20-month explants, there were no other significant differences (p > 0.05) found between any of the other principal valve ECM components (collagen and elastin) at the leaflet, annulus, or chordae tendinea locations, across these time points. In particular, neochordae tissue had formed, which seamlessly integrated with the native papillary muscles. However, additional processing will be required to trigger accelerated, uniform and complete valve ECM formation in the recipient. Regardless of the specific processing done to the bioscaffold valve, in this proof-of-concept study, we estimate that a 3-month window following bioscaffold valve replacement is the timeline in which complete regeneration of the valve and integration with the host needs to occur.

Abstract
BACKGROUND Animal data demonstrate that intracardiac patches of decellularized porcine small intestine submucosa (CorMatrix; CorMatrix Cardiovascular, Atlanta, GA) become repopulated with native cells, suggesting the possibility of a substrate for regenerative tissue in humans. Although human studies have not demonstrated this regenerative property with intracardiac patches, it is possible that other environments may better promote native cell repopulation. We report a prospective series of explanted CorMatrix extracardiac patches placed in infants with congenital heart disease. METHODS CorMatrix Tyke patches were used in pulmonary artery patch closure during the Norwood procedure. The patch material was explanted as part of the hemi-Fontan procedure. Specimens were analyzed with the use of hematoxylin and eosin, Movat pentachrome, and trichrome stains. RESULTS Of the 11 implantations, 9 specimens were explanted. One patient did not survive to hemi-Fontan procedure. One patient's patch was removed, but not analyzed. Acellular material, chronic inflammation, fibrosis, and foreign body giant cell reaction was seen in all explanted patches. No explanted CorMatrix Tyke material demonstrated evidence of ingrowth of native endothelial tissue at a median of 4.9 months in vivo. CONCLUSIONS CorMatrix Tyke patch material, placed as a pulmonary artery patch in an extracardiac position, remained pliable and mostly free of calcification. However, these patches did not show evidence of native endothelial tissue at a median of 4.9 months in vivo.

Abstract
Background: Conceptually, a tissue engineered heart valve would be especially appealing in the pediatric setting since small size and somatic growth constraints would be alleviated. In this study, we utilized porcine small intestinal submucosa (PSIS) for valve replacement. Of note, we evaluated the material responses of PSIS and subsequently its acute function and somatic growth potential in the mitral position. Methods and Results: Material and mechanical assessment demonstrated that both fatigued 2ply (∼65 μm) and 4ply (∼110 μm) PSIS specimens exhibited similar failure mechanisms, but at an accelerated rate in the former. Specifically, the fatigued 2ply PSIS samples underwent noticeable fiber pullout and recruitment on the bioscaffold surface, leading to higher yield strength (p < 0.05) and yield strain (p < 0.05) compared to its fatigued 4ply counterparts. Consequently, 2ply PSIS mitral valve constructs were subsequently implanted in juvenile baboons (n = 3). Valve function was longitudinally monitored for 90 days postvalve implantation and was found to be robust in all animals. Histology at 90 days in one of the animals revealed the presence of residual porcine cells, fibrin matrix, and host baboon immune cells but an absence of tissue regeneration. Conclusions: Our findings suggest that the altered structural responses of PSIS, postfatigue, rather than de novo tissue formation, are primarily responsible for the valve's ability to accommodate somatic growth during the acute phase (90 days) following mitral valve replacement. Impact Statement Tissue engineered heart valves (TEHVs) offer the potential of supporting somatic growth. In this study, we investigated a porcine small intestinal submucosa bioscaffold for pediatric mitral heart valve replacement. The novelty of the study lies in identifying material responses under mechanical loading conditions and its effectiveness in being able to function as a TEHV. In addition, the ability of the scaffold valve to support acute somatic growth was evaluated in the Baboon model. The current study contributes toward finding a solution for critical valve diseases in children, whose current prognosis for survival is poor.

Abstract
We developed a nucleus pulposus cell (NPC)-modulated decellularized small intestinal submucosa (SIS) scaffold, and assessed the ability of this material to prevent Intervertebral disc degeneration (IVD) degeneration. Decellularized porcine SIS was squashed into particles and the biological safety and efficiency of these particles were evaluated. Next, SIS particles were seeded with rabbit NPCs, cultured for two months in vitro, decellularized again and suspended for intervertebral injection. We demonstrated that use of the decellularization protocol resulted in the removal of cellular components with maximal retention of extracellular matrix. The xenogeneic decellularized SIS did not display cytotoxicity in vitro and its application prevented NPC degradation. Furthermore, the xenogeneic SIS microparticles were effective in preventing IVD progression in vivo in a rabbit disc degeneration model. In conclusion, our study describes an optimized method for decellularized SIS preparation and demonstrated that the material is safe and effective for treating IVD degeneration.

Abstract
Tissue engineering and regenerative medicine have adopted the use of extracellular matrix (ECM) as a cell delivery device and bioactive regenerative agent. To this end, many ECMs have been investigated for cardiac tissue engineering and regenerative medicine applications with variable success. Many sources of natural ECMs have been tested for cardiac applications. Typically, natural ECMs have been made from decellularized organs or tissues and processed into either sheets or injectable hydrogels. This chapter will review natural sources of ECM materials that have been tested as therapeutic agents in models of heart failure.

Abstract
Extracellular matrix (ECM) derived from small intestinal submucosa (SIS) is widely used in clinical applications as a scaffold for tissue repair. Recently, CorMatrix® porcine SIS-ECM (CorMatrix Cardiovascular, Inc., Roswell, GA, USA) has gained popularity for 'next-generation' cardiovascular tissue engineering due to its ease of use, remodelling properties, lack of immunogenicity, absorbability and potential to promote native tissue growth. Here, we provide an overview of the biology of porcine SIS-ECM and systematically review the preclinical and clinical literature on its use in cardiovascular surgery. CorMatrix® has been used in a variety of cardiovascular surgical applications, and since it is the most widely used SIS-ECM, this material is the focus of this review. Since CorMatrix® is a relatively new product for cardiovascular surgery, some clinical and preclinical studies published lack systematic reporting of functional and pathological findings in sufficient numbers of subjects. There are also emerging reports to suggest that, contrary to expectations, an undesirable inflammatory response may occur in CorMatrix® implants in humans and longer-term outcomes at particular sites, such as the heart valves, may be suboptimal. Large-scale clinical studies are needed driven by robust protocols that aim to quantify the pathological process of tissue repair.

Abstract
Gels derived from decellularized small intestinal submucosa (SIS) have been used to repair ischemic myocardium and deliver protein drug. However, their material properties and effects on cell behavior are not well understood, in part because of the difficulty of gelling in vitro. In this study, soluble SIS matrix, which was easily handled and could effectively gel, was successfully prepared using a modified method. Fourier transform infrared spectroscopy confirmed that the SIS gel contained not only collagen but also sulfated glycosaminoglycans (sGAGs). Interestingly, the sustained release of vascular endothelial growth factor and basic fibroblast growth factor within the SIS gel was detected, and no initial burst release was observed. The SIS gel was more capable of evoking neovascularization than collagen type I gel, as determined by tube formation experiments in human umbilical vein endothelial cells, the mouse aortic ring assay, and animal experiments. The upregulated expression of kinase insert domain receptor (KDR), Notch1, and Ang2, the key genes in angiogenesis that were evaluated in HUVECs seeded on the SIS gel, confirmed that angiogenesis bioactive factors contained in the SIS gel are indeed active and effective. The SIS gel significantly promoted neovascularization compared to the collagen type I gel in vivo. Histology revealed adequate host tissue response in engraftment both types of gels. Together, these data demonstrate that the SIS gel is a promising and attractive candidate for tissue engineering, especially in promoting vessel formation. STATEMENT OF SIGNIFICANCE The material properties of small intestinal submucosa (SIS) gel and the effect of these properties upon cell behavior are not well understood, in part due to the difficulty of gelling in vitro. In this study, soluble SIS matrix, which was easily handled and gelled was prepared using modified method. The material properties and biocompatibility of SIS gel were explored. The sustained release of growth factors from this gel was observed along with its degradation in vitro. The results demonstrate that the SIS gel promote angiogenesis in vitro and in vivo. The SIS gel biological properties suggest that the constituent ECM molecules released from the gel remain activity. These findings suggested that the SIS gel was a promising candidate for tissue engineering, especially in promoting vessel formation.

Abstract
Biomaterials with direct intramyocardial injection devices have been developed and are being investigated as a potential cardiac regenerative therapy for end-stage ischemic heart failure. Decellularized extracellular matrix (ECM) has been shown to improve cardiac function and attenuate or reverse pathologic remodeling cascades. CorMatrix Cardiovascular, Inc. has developed a porcine small intestinal submucosa-derived particulate extracellular matrix (P-ECM) and ECM Delivery System to provide uniform and controlled intramyocardial delivery of the injectable P-ECM material into infarcted regions. The CorMatrix ECM Delivery System is composed of a Multi-Needle P-ECM Syringe Assembly, Automated Injection Controller, and Tissue Depth Measurement System (portable ultrasound). Feasibility of the P-ECM delivery system was tested intraoperatively in a chronic ischemic heart failure bovine model (n = 11), and demonstrated the ability to control injection volume (0.1-1.0 ml) and depth of penetration (3-5 mm) under regulated injection pressure (150 psi CO2) into the ischemic region. Targeted intramyocardial delivery of P-ECM may improve efficacy and enable development of novel patient-specific therapy.

Abstract
An ideal material for repair of congenitally malformed hearts would encourage tissue regeneration with growth potential. Decellularized porcine small intestinal submucosa extracellular matrix (SIS-ECM) promotes tissue regeneration in animal models and noncardiac human applications. This retrospective review evaluates SIS-ECM for reconstruction of congenital heart defects. From June 2007 to May 2009, SIS-ECM patches were used in 43 operations on 40 patients aged 2 days to 13 years. In 16 cases, the SIS-ECM was used for pericardial closure. The SIS-ECM was used for cardiac or great vessel repair in 37 cases: atrial septal defect repair in 11, pulmonary arterioplasty in 10, right ventricular outflow tract patch in 6, pulmonary monocusp valve creation in 5, superior vena cava patch in 2 and aortoplasty in 2, valve leaflet augmentation in 2, and repair of unroofed coronary sinus in 1. Follow-up was complete. There were 5 deaths, all unrelated to the SIS-ECM. Mean follow-up was 7.85 months (0.5-24 months). No pericardial effusions or intracardiac or intravascular thromboses occurred related to the SIS-ECM. The patches did not shrink or calcify. Four of 5 monocusp valves were competent and none were stenotic. One patient who underwent tricuspid valve anterior leaflet augmentation with SIS-ECM required tricuspid valve replacement 4 months later for severe regurgitation following a catheter-based procedure. Explanted tissue showed resorption of the SIS-ECM, replacement with organized collagen, and re-endothelialization. Repair of congenital heart defects using SIS-ECM is feasible and safe. In valve reconstruction, this procedure shows potential for replacement by autologous tissue. Longer-term follow-up is required to assess the potential for growth.

Abstract
Tissue engineering (TE) is an emerging interdisciplinary field aiming at the restoration or improvement of impaired tissue function. A combination of cells, scaffold materials, engineering methods, and biochemical and physiological factors is employed to generate the desired tissue substitute. Scaffolds often play a pivotal role in the engineering process supporting a three-dimensional tissue formation. The ideal scaffold should mimic the native extracellular environment providing mechanical and biological properties to allow cell attachment, migration, and differentiation, as well as remodeling by the host organism. The scaffold should be nonimmunogenic and should ideally be resorbed by the host over time, leaving behind only the regenerated tissue. More than 40 years ago, a preparation of the small intestine was introduced for the replacement of vascular structures. Since then the small intestinal submucosa (SIS) has gained a lot of interest in TE and subsequent clinical applications, as this material exhibits key features of a highly supportive scaffold. This review will focus on the general properties of the SIS and its applications in therapeutical approaches as well as in generating tissue substitutes in vitro. Furthermore, the main problem of TE, which is the insufficient nourishment of cells within three-dimensional, artificial tissues exceeding certain dimensions is addressed. To solve this issue the implementation of another small intestine-derived preparation, the biological vascularized matrix (BioVaM), could be a feasible option. The BioVaM comprises in addition to SIS the arterial and venous mesenteric pedicles and exhibits thereby a perfusable vessel bed that is preserved after decellularization.

Abstract
Porcine small intestinal submucosa (SIS) of Cook Biotech is licensed and widely used for tissue remodeling in humans. SIS was shown to be highly effective as an adjuvant in model studies with prostate and ovarian cancer vaccines. However, SIS adjuvanticity relative to alum, another important human-licensed adjuvant, has not yet been delineated in terms of activation of innate immunity via inflammasomes and boosting of antibody responses to soluble proteins and hapten-protein conjugates. We used ovalbumin, and a hapten-protein conjugate, phthalate-keyhole limpet hemocyanin. The evaluation of SIS was conducted in BALB/c and C57BL/6 mice using both intraperitoneal and subcutaneous routes. Inflammatory responses were studied by microarray profiling of chemokines and cytokines and by qPCR of inflammasomes-related genes. Results showed that SIS affected cytokine and chemokines microenvironments such as up-regulation of IL-4 and CD30-ligand and activation of chemotactic factors LIX and KC (neutrophil chemotactic factors), MCP-1 (monocytes chemotactic factors), MIP 1-α (macrophage chemotactic factor) and lymphotactin, as well as, growth factors like M-CSF. SIS also promoted gene expression of Nod-like receptors (NLR) and associated downstream effectors. However, in contrast to alum, SIS had no effects on pro-inflammatory cytokines (IL-6, IL-1β, TNF-α) or NLRP3, but it appeared to promote both Th1 and Th2 responses under different conditions. Lastly, it was as effective as alum in engendering a lasting and specific antibody response, primarily of IgG1 type.

Abstract
Major bile duct lesions are usually treated by a hepaticojejunostomy which is often complicated by cholangitis and liver fibrosis. The aim of this study was to investigate the morphologic features of a neo-bile duct created from a vein and a biodegradable endoluminal stent. The neo-bile duct was created using a segment of the external jugular vein which was endoluminally stented by a biodegradable poly-lactate-acid stent. In 18 pigs, the common bile duct was resected and replaced by the vein with (n = 12) or without endoluminal stent (n = 6). Six animals served as controls. Survival, liver function and morphological changes of the neo-bile duct and the liver were observed for six months. After six months, the neo-bile duct morphologically resembled the native bile duct showing Ck7-positive columnar epithelium and newly formed capillaries in the bile duct wall. The biodegradable stent disappeared after four months. All animals survived and showed normal liver function and no cholestasis. In contrast, after sole vein reconstruction of the bile duct, four animals died due to biliary peritonitis and cholangitis. Creation of a neo-bile duct which morphologically resembles the native bile duct is feasible by using a body's own vein and a biodegradable endoluminal stent.

Abstract
Few manuscripts describe the construction of an adipose tissue composite flap able to create an in vivo microenvironment and a neovasculature that can grow with and service implanted adipose tissue. Creation of an in vivo vascular carrier and tissue chamber for volume-stable transplanted adipose tissue was attempted using jejunum segments with intact circulation in 18 male Wistar rats. Intestinal segments were filled with autologous adipose tissue. Histologic (hematoxylin-eosin), immunohistochemical (antibodies to leptin and to vascular endothelial growth factor) and ultrastructural analyses were used to evaluate the results at 6, 18, and 60 days after surgery. Macroscopic observation confirmed the feasibility of this prefabricated adipose tissue flap: no loss of weight or volume occurred at any time point. Histologic analysis showed normal morphologic features of transplanted adipose tissue. Immunohistochemical studies confirmed the vitality of adipose tissue and the presence of a microvascular network within the flap. Small intestinal segments denuded of the mucosal layer can support in vivo transplanted adipose tissue.

Abstract
Background—
The use of permanent synthetic implants to close atrial septal defects (ASD) and patent foramen ovale (PFO) has a number of limitations, including late complications and the limiting of transeptal access to the left heart should it be required for the later treatment of acquired heart disease. BioSTAR is a novel, bioabsorbable, atrial septal repair implant. This phase I pilot study evaluates the feasibility, safety, and effectiveness of BioSTAR for the first time in humans.
Methods and Results—
We conducted a prospective, open-label, multicenter clinical study in 58 patients aged 28 to 68 years who had a clinically significant ASD or PFO. Percutaneous shunt closure was undertaken with the BioSTAR septal repair implant. Successful device implantation was achieved in 57 (98%) of 58 patients. Closure at 30 days and 6 months, assessed by contrast transthoracic echocardiography, was 48 (92%) of 52 and 54 (96%) of 56, respectively. There was no evidence of a clinically significant response to the device. Transient atrial arrhythmia occurred in 5 patients after implantation. No major safety issues were observed.
Conclusions—
This study demonstrates the feasibility, safety, and effectiveness of BioSTAR for the closure of ASD and PFO in humans with a high rate of early and complete shunt closure. BioSTAR is a novel septal repair implant designed to provide biological closure of atrial-level defects using the patient’s natural healing response. Because 90% to 95% of the implant is absorbed and replaced with healthy native tissue, future access to the left atrium may be achieved.
