Abstract
Diabetes has been one of the major concerns in recent years, due to the increasing rate of morbidity and mortality worldwide. The available treatment strategies for uncontrolled diabetes mellitus (DM) are pancreas or islet transplantation. However, these strategies are limited due to unavailability of quality pancreas/ islet donors, life-long need of immunosuppression, and associated complications. Cell therapy has emerged as a promising alternative options to achieve the clinical benefits in the management of uncontrolled DM. Since the last few years, various sources of cells have been used to convert into insulin-producing β-like cells. These extrapancreatic sources of cells may play a significant role in β-cell turnover and insulin secretion in response to environmental stimuli. Stem/progenitor cells from liver have been proposed as an alternative choice that respond well to glucose stimuli under strong transcriptional control. The liver is one of the largest organs in the human body and has a common endodermal origin with pancreatic lineages. Hence, liver has been proposed as a source of a large number of insulin-producing cells. The merging of nanotechnology and 3D tissue bioengineering has opened a new direction for producing islet-like cells suitable for in vivo transplantation in a cordial microenvironment. This review summarizes extrapancreatic sources for insulin-secreting cells with reference to emerging technologies to fulfill the future clinical need.

Abstract
Sterilization is the process of killing all microorganisms, while disinfection is the process of killing or removing all kinds of pathogenic microorganisms except bacterial spores. Biomaterials involved in cell experiments, animal experiments, and clinical applications need to be in the aseptic state, but their physical and chemical properties as well as biological activities can be affected by sterilization or disinfection. Decellularized matrix (dECM) is the low immunogenicity material obtained by removing cells from tissues, which retains many inherent components in tissues such as proteins and proteoglycans. But there are few studies concerning the effects of sterilization or disinfection on dECM, and the systematic introduction of sterilization or disinfection for dECM is even less. Therefore, this review systematically introduces and analyzes the mechanism, advantages, disadvantages, and applications of various sterilization and disinfection methods, discusses the factors influencing the selection of sterilization and disinfection methods, summarizes the sterilization and disinfection methods for various common dECM, and finally proposes a graphical route for selecting an appropriate sterilization or disinfection method for dECM and a technical route for validating the selected method, so as to provide the reference and basis for choosing more appropriate sterilization or disinfection methods of various dECM. Asepsis is the prerequisite for the experiment and application of biomaterials. Sterilization or disinfection affects physic-chemical properties of biomaterials. Mechanism, advantages and disadvantages of sterilization or disinfection methods. Factors influencing the selection of sterilization or disinfection methods. Selection of sterilization or disinfection methods for decellularized matrix.

Abstract
The spleen is considered a non-essential organ. However, its importance is increasingly clear, given the serious disorders caused by its absence or dysfunction, e.g., greater susceptibility to infections, thromboembolism and cancer. Surgical techniques to preserve the spleen and maintain splenic function have become increasingly common. However, the morbidity and mortality associated with its absence and dysfunction are still high. We used the decellularization technique to obtain a viable splenic scaffold for recellularization in vitro and propose the idea of bioengineered spleen transplantation to the host. We observed the maintenance of important structural components such as white pulp, marginal zone and red pulp, in addition to the network of vascular ducts. The decellularized scaffold presents minimal residual DNA and SDS, which are essential to prevent immunogenic responses and transplantation failure. Also, the main components of the splenic matrix were preserved after decellularization, with retention of approximately 72% in the matrisomal protein content. The scaffold we developed was partially recellularized with stromal cells from the spleen of neonatal rats, demonstrating adhesion, proliferation and viability of cells. Therefore, the splenic scaffold is very promising for use in studies on spleen reconstruction and transplantation, with the aim of complete recovery of splenic function.

The Fabrication and Evaluation of a Potential Biomaterial Produced with Stem Cell Sheet Technology for Future Regenerative Medicine. Stem Cells Int 2020; 2020:9567362.

Abstract
To date, the decellularized scaffold has been widely explored as a source of biological scaffolds for regenerative medicine. However, the acellular matrix derived from natural tissues and organs has a lot of defects, including the limited amount of autogenous tissue and surgical complication such as risk of blood loss, wound infection, pain, shock, and functional damage in the donor part of the body. In this study, we prepared acellular matrix using adipose-derived stem cell (ADSC) sheets and evaluate the cellular compatibility and immunoreactivity. The ADSC sheets were fabricated and subsequently decellularized using repeated freeze-thaw, Triton X-100 and SDS decellularization. Oral mucosal epithelial cells were seeded onto the decellularized ADSC sheets to evaluate the cell replantation ability, and silk fibroin was used as the control. Then, acellular matrix was transplanted onto subcutaneous tissue for 1 week or 3 weeks; H&E staining and immunohistochemical analysis of CD68 expression and quantitative real-time PCR (qPCR) were performed to evaluate the immunogenicity and biocompatibility. The ADSC sheet-derived ECM scaffolds preserved the three-dimensional architecture of ECM and retained the cytokines by Triton X-100 decellularization protocols. Compared with silk fibroin in vitro, the oral mucosal epithelial cells survived better on the decellularized ADSC sheets with an intact and consecutive epidermal cellular layer. Compared with porcine small intestinal submucosa (SIS) in vivo, the homogeneous decellularized ADSC sheets had less monocyte-macrophage infiltrating in vivo implantation. During 3 weeks after transplantation, the mRNA expression of cytokines, such as IL-4/IL-10, was obviously higher in decellularized ADSC sheets than that of porcine SIS. A Triton X-100 method can achieve effective cell removal, retain major ECM components, and preserve the ultrastructure of ADSC sheets. The decellularized ADSC sheets possess good recellularization capacity and excellent biocompatibility. This study demonstrated the potential suitability of utilizing acellular matrix from ADSC sheets for soft tissue regeneration and repair.

Abstract
OBJECTIVE To construct a decellularized matrix of human fatty liver as the scaffold for three-dimensional (3D) culture of hepatocarcinoma cells. METHODS Human fatty liver decellularized matrix (hFLM) was prepared by repeated freezingthawing, perfusion with gradient SDS and 1% Triton X-100 through the portal vein and hepatic artery, and repeated agitation with Triton X-100. HepG2 cells were cultured in the prepared hFLM, and the cell survival, morphology, proliferation and cellular expressions of the adhesion molecules were detected. RESULTS The decellularization procedure shortened the time for scaffold preparation and preserved the 3D ultrastructure and the composition of the extracellular matrix. HepG2 cells cultured in hFLM scaffold maintained proliferation for up to 15 days and showed a growth pattern with a long lag phase and a slow growth rate, which was similar to the growth pattern in vivo. The cultured HepG2 exhibited a low expression of E-cadherin and a high expression of vimentin, which was consistent with the xenograft but opposite to 2D cultured cells. However, the lack of adequate nutrient transport in this hepatocarcinoma cell model led to a slowdown of cell proliferation in the later stage. The PCNA index of HepG2 cells cultured in hFLM was lowered by 29.3% on day 12 as compared with that on day 6. CONCLUSIONS We established a new protocol for preparing hFLM and confirmed the feasibility of constructing hepatocarcinoma cell models using the hFLM scaffold.

Abstract
Thrombogenicity is the predominant obstacle to successful implantation of decellularized spleen matrix (DSM). The aim of this study was to construct a transplantable functional bioartificial liver (BAL) with the use of DSM. This was achieved by layer-by-layer electrostatic immobilization technique by using poly dimethyl diallyl ammonium chloride and heparin. After heparin immobilization, DSM gradually turned from translucent into completely opaque milky white. Toluidine blue staining showed strong positive staining of the entire coated DSM. In vitro diluted blood perfusion test showed that the splenic arterial pressure of the heparin-coated DSM was much lower than that of the non-coated DSM (p < 0.01). Then, we heterotopically transplanted the modified DSM into rat hepatic injury model for 6 h to evaluate the hemocompatibility in vivo. Overall, HE staining and vWF immunohistochemistry all confirmed that heparin-coated DSM has a satisfactory anticoagulant effect. Based on the heparin-coated DSM, BALs were built with the use of rat primary hepatocytes. Our results demonstrate that these heparin-coated BALs satisfied anticoagulant effects even after 6 h. Immunofluorescence of ALB and G6PC also showed that hepatocytes in heparin-coated BAL have significantly higher cell viability and function than the non-coated group. However, serum analysis did not indicate a significant difference between the two groups but a slight trend of improvement with respect to serum albumin (p = 0.156) and aspartate transaminase (p = 0.140). In conclusion, we demonstrated that the BAL constructed by heparin-coated DSM can exert satisfactory short-term anticoagulant effects and can compensate for a certain degree of liver function.

Abstract
BACKGROUND The present study has been aimed to identify molecular dynamics of pancreatic transcription factors (pTFs) during events of directed trans-differentiation of human hepatic progenitor cells (hHPCs) into insulin producing cells (InPCs) within bioengineered humanized neoorgan. The study demonstrates applicability of acellularized whole splenic scaffold (ASOS) to generate insulin producing humanized transplantable neoorgan through activation of pancreatic transcription factors. METHODS An efficient acellularization process was developed for xenogeneic rat spleen using change in different gradients of reagents perfusion through splenic artery for varying time points. The acellularized xenogeneic spleen scaffold was characterized thoroughly for preservation of extra-cellular matrix and retention of organ specific vasculature and mechanical properties. Further scaffolds were sterilized and repopulated with hHPCs which were triggered using a stage wise induction with growth factors and hyperglycemic challenge for trans-differentiation into InPCs. Dynamics of pTFs alone or simultaneously during induction process was identified using gene expression analysis and immunological staining. RESULTS The cells within the engineered neoorgan respond to growth factors and extrinsic hyperglycemic challenge and generate large number of InPCs under controlled dynamic regulation of pTFs. Highly controlled regulation of pTFs generates higher percentage of Nkx-6.1+/C-peptide+ cells within the engineered splenic scaffolds. Generation of high percentage of insulin and C-peptide positive cells in three-dimensional organ architecture responded better to hyperglycemic stimuli and produced higher quantity of insulin than 2D-culture system. CONCLUSION The present study provides a novel platform for designing effective regenerative strategies using whole organ scaffolds to control hyperglycemia under tight regulation of pTFs using humanized neoorgan system.

Abstract
OBJECTIVE To explore the optimal implantation strategy of tissue-engineered liver (TEL) constructed based on decellularized spleen matrix (DSM) in rats. METHODS DSM was prepared by freeze-thawing and perfusion with sodium dodecyl sulfate (SDS) of the spleen of healthy SD rats. Primary rat hepatocytes isolated using modified Seglen 2-step perfusion method were implanted into the DSM to construct the TEL. The advantages and disadvantages were evaluated of 4 transplant strategies of the TEL, namely ectopic vascular anastomosis, liver cross-section suture transplantation, intrahepatic insertion and mesenteric transplantation. RESULTS The planting rate of hepatocytes in the DSM was (74.5∓7.7)%. HE staining and scanning electron microscopy showed satisfactory cell status, and immunofluorescence staining confirmed the normal expression of ALB and G6Pc in the cells. For TEL implantation, ectopic vascular anastomosis was difficult and resulted in a mortality rate of 33.3% perioperatively and massive thrombus formation in the matrix within 6 h. Hepatic cross-section suture failed to rapidly establish sufficient blood supply, and no viable graft was observed 3 days after the operation. With intrahepatic insertion method, the hepatocytes in the DSM could survive as long as 14 days. Mesenteric transplantation resulted in a hepatocyte survival rate of (38.3+7.1)% at 14 days after implantation. CONCLUSION TEL constructed based on DSM can perform liver-specific functions with a good cytological bioactivity. Mesenteric transplantation of the TEL, which is simple, safe and effective, is currently the optimal transplantation strategy.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has become a major risk factor for hepatocellular carcinoma (HCC) worldwide. However, the underlying mechanism remains insufficiently elucidated. The expression of Collagen I, an important component of extracellular matrix (ECM), was increased during the progression from simple steatosis to NASH. The purpose of this study was to investigate the role of Collagen I in NAFLD-related HCC. To study this, the decellularized liver matrix, which preserves the pathological changes of ECM, was prepared from the human fatty liver (FLM) and human normal liver (NLM). HepG2 cells cultured in FLM had a higher proliferation rate than those in NLM. SMMC-7721 and HepG2 cells cultured on Collagen I-coated plates grew faster than those on either Collagen IV- or fibronectin-coated plates. This effect was dose-dependent and associated with elevated integrin β1 expression and activation of downstream phospho-FAK. Knocking down the expression of integrin β1 significantly decreased the proliferation of HCC cells. Additionally, an orthotopic tumor model was established in NAFLD mice at different stages. The over-expressed Collagen I in the mice liver increased the expression of integrin β1 and downstream phospho-FAK, resulting in the proliferation of HCC cells. This proliferation could be inhibited by blocking the integrin β1/FAK pathway. In summary, our study demonstrated that Collagen I promoted HCC cell proliferation by regulating the integrin β1/FAK pathway. Decellularized liver matrix can be used as a platform to three-dimensionally culture HCC cells and reproduce the impact of changed ECM on the progression of NAFLD-related HCC.

Abstract
Regenerative medicine is a rapidly advancing field that uses principles of tissue engineering, developmental biology, stem cell biology, immunology, and bioengineering to reconstruct diseased or damaged tissues. Biologic scaffolds composed of extracellular matrix have shown great promise as an inductive substrate to facilitate the constructive remodeling of gastrointestinal (GI) tissue damaged by neoplasia, inflammatory bowel disease, and congenital or acquired defects. The present review summarizes the preparation and use of extracellular matrix scaffolds for bioengineering of the GI tract, identifies significant advances made in regenerative medicine for the reconstruction of functional GI tissue, and describes an emerging therapeutic approach.

Abstract
BACKGROUND AND AIMS Decellularized liver matrix (DLM) hold great potential for reconstructing functional hepatic-like tissue (HLT) based on reseeding of hepatocytes or stem cells, but the shortage of liver donors is still an obstacle for potential application. Therefore, an appropriate alternative scaffold is needed to expand the donor pool. In this study, we explored the effectiveness of decellularized spleen matrix (DSM) for culturing of bone marrow mesenchymal stem cells (BMSCs), and promoting differentiation into hepatic-like cells. METHODS Rats' spleen were harvested for DSM preparation by freezing/thawing and perfusion procedure. Then the mesenchymal stem cells derived from rat bone marrow were reseeded into DSM for dynamic culture and hepatic differentiation by a defined induction protocol. RESULTS The research found that DSM preserved a 3-dimensional porous architecture, with native extracellular matrix and vascular network which was similar to DLM. The reseeded BMSCs in DSM differentiated into functional hepatocyte-like cells, evidenced by cytomorphology change, expression of hepatic-associated genes and protein markers, glycogen storage, and indocyanine green uptake. The albumin production (2.74±0.42 vs. 2.07±0.28 pg/cell/day) and urea concentration (75.92±15.64 vs. 52.07±11.46 pg/cell/day) in DSM group were remarkably higher than tissue culture flasks (TCF) group over the same differentiation period, P< 0.05. CONCLUSION This present study demonstrated that DSM might have considerable potential in fabricating hepatic-like tissue, particularly because it can facilitate hepatic differentiation of BMSCs which exhibited higher level and more stable functions.
