Mesenchymal Stromal Cell on Liver Decellularised Extracellular Matrix for Tissue Engineering. Biomedicines 2022; 10:biomedicines10112817.

Abstract
Background: In end-stage chronic liver disease, transplantation represents the only curative option. However, the shortage of donors results in the death of many patients. To overcome this gap, it is mandatory to develop new therapeutic options. In the present study, we decellularised pig livers and reseeded them with allogeneic porcine mesenchymal stromal cells (pMSCs) to understand whether extracellular matrix (ECM) can influence and/or promote differentiation into hepatocyte-like cells (HLCs). Methods: After decellularisation with SDS, the integrity of ECM-scaffolds was examined by histological staining, immunofluorescence and scanning electron microscope. DNA quantification was used to assess decellularisation. pMSCs were plated on scaffolds by static seeding and maintained in in vitro culture for 21 days. At 3, 7, 14 and 21 days, seeded ECM scaffolds were evaluated for cellular adhesion and growth. Moreover, the expression of specific hepatic genes was performed by RT-PCR. Results: The applied decellularisation/recellularisation protocol was effective. The number of seeded pMSCs increased over the culture time points. Gene expression analysis of seeded pMSCs displayed a weak induction due to ECM towards HLCs. Conclusions: These results suggest that ECM may address pMSCs to differentiate in hepatocyte-like cells. However, only contact with liver-ECM is not enough to induce complete differentiation.

Abstract
Hepatocytes are liver parenchymal cells involved in performing various metabolic reactions. During the development of therapeutic drugs, toxicological assays are conducted using hepatocyte cultures before clinical trials. However, since primary hepatocytes cannot proliferate and rapidly lose their functions in vitro, many efforts have been put into modifying culture conditions to expand primary hepatocytes and induce hepatocyte functions in intrinsic and extrinsic stem/progenitor cells. In this chapter, we summarize recent advances in preparing hepatocyte cultures and induction of hepatocytes from various cellular sources.

Abstract
Mesenchymal stem cell transplantation is an emerging therapy for treating chronic liver diseases. The potential of this treatment has been evaluated in preclinical and clinical studies. Although the mechanisms of mesenchymal stem cell transplantation are still not completely understood, accumulating evidence has revealed that their immunomodulation, differentiation, and antifibrotic properties play a crucial role in liver regeneration. The safety and therapeutic effects of mesenchymal stem cells in patients with chronic liver disease have been observed in many clinical studies. However, only modest improvements have been seen, partly because of the limited feasibility of transplanted cells at present. Here, we discuss several strategies targeted at improving viable cell engraftment and the potential challenges in the use of extracellular vesicle-based therapies for liver disease in the future.

Abstract
Neonatal hypoxic ischemia (HI) results in different extents of brain damage, and immature brain tissue is particularly sensitive to the stimulation of HI. Hypoxic-ischemic brain damage (HIBD) is a common and serious nervous system disease in neonates, for both full-term infants and preterm infants, and is one of the main causes of neonatal death. The surviving infants are often associated with cerebral palsy, mental retardation, and other sequelae, which severely affect quality of life. For term infants, hypoxia and ischemia mainly affect gray matter, whereas in preterm infants, the white matter. However, up to now, inadequate standards and specific measures that can be used to treat hypoxic-ischemic brain injury are available. Recently, in addition to supportive therapy and symptomatic treatment, research on the treatment of hypoxic-ischemic brain injury has focused on the following aspects: hypothermia therapy, stem cell therapy, neuroprotective agents, ibuprofen, and combination therapy. In this review, we will summarize the treatment of HIBD and make suggestions for the future treatment direction.

Abstract
Allogeneic liver transplantation is still deemed the gold standard solution for end-stage organ failure; however, donor organ shortages have led to extended waiting lists for organ transplants. In order to overcome the lack of donors, the development of new therapeutic options is mandatory. In the last several years, organ bioengineering has been extensively explored to provide transplantable tissues or whole organs with the final goal of creating a three-dimensional growth microenvironment mimicking the native structure. It has been frequently reported that an extracellular matrix-based scaffold offers a structural support and important biological molecules that could help cellular proliferation during the recellularization process. The aim of the present review is to underline the recent developments in cell-on-scaffold technology for liver bioengineering, taking into account: (1) biological and synthetic scaffolds; (2) animal and human tissue decellularization; (3) scaffold recellularization; (4) 3D bioprinting; and (5) organoid technology. Future possible clinical applications in regenerative medicine for liver tissue engineering and for drug testing were underlined and dissected.

Mesenchymal Stem Cells for Liver Regeneration in Liver Failure: From Experimental Models to Clinical Trials. Stem Cells Int 2019; 2019:3945672.

Abstract
The liver centralizes the systemic metabolism and thus controls and modulates the functions of the central and peripheral nervous systems, the immune system, and the endocrine system. In addition, the liver intervenes between the splanchnic and systemic venous circulation, determining an abdominal portal circulatory system. The liver displays a powerful regenerative potential that rebuilds the parenchyma after an injury. This regenerative mission is mainly carried out by resident liver cells. However, in many cases this regenerative capacity is insufficient and organ failure occurs. In normal livers, if the size of the liver is at least 30% of the original volume, hepatectomy can be performed safely. In cirrhotic livers, the threshold is 50% based on current practice and available data. Typically, portal vein embolization of the part of the liver that is going to be resected is employed to allow liver regeneration in two-stage liver resection after portal vein occlusion (PVO). However, hepatic resection often cannot be performed due to advanced disease progression or because it is not indicated in patients with cirrhosis. In such cases, liver transplantation is the only treatment possibility, and the need for transplantation is the common outcome of progressive liver disease. It is the only effective treatment and has high survival rates of 83% after the first year. However, donated organs are becoming less available, and mortality and the waiting lists have increased, leading to the initiation of living donor liver transplantations. This type of transplant has overall complications of 38%. In order to improve the treatment of hepatic injury, much research has been devoted to stem cells, in particular mesenchymal stem cells (MSCs), to promote liver regeneration. In this review, we will focus on the advances made using MSCs in animal models, human patients, ongoing clinical trials, and new strategies using 3D organoids.

Abstract
We have compared the transcriptomic profiles of human induced pluripotent stem cells after their differentiation in hepatocytes like cells in plates and microfluidic biochips. The biochips provided a 3D and dynamic support during the cell differentiation when compared to the 2D static cultures in plates. The microarray have demonstrated the up regulation of important pathway related to liver development and maturation during the culture in biochips. Furthermore, the results of the transcriptomic profile, coupled with immunostaining, and RTqPCR analysis have shown typical biomarkers illustrating the presence of responders of biliary like cells, hepatocytes like cells, and endothelial like cells. However, the overall tissue still presented characteristic of immature and foetal patterns. Nevertheless, the biochip culture provided a specific micro-environment in which a complex multicellular differentiation toward liver could be oriented.

Abstract
In this study, we constructed a microporous hydrogel scaffold with hexagonally packed interconnected cavities and extracellular matrix (ECM)-functionalized interior surface, and systematically investigated the hepatic differentiation of human adipose-derived mesenchymal stem cells (hAD-MSCs) under the influence of three key factors: three-dimensional (3D) geometry, ECM presence, and coculture with hepatocyte-derived cell line. Results confirmed that (i) hepatic differentiation of hAD-MSC is more efficient in a 3D microporous scaffold than in 2D monolayer culture; (ii) the presence of both ECM components (fibronectin and collagen-I) in the scaffold is superior to collagen-I only, highlighting the importance of fibronectin; and (iii) coculture with Huh-7.5 hepatocyte-derived cells promoted liver-specific functions of the hAD-MSC-derived hepatocytes. The optimized differentiation process only took 21 days to complete, a time length that is shorter or at least comparable to previous reports, and more importantly, yielded an albumin production more than 10-fold higher than conventional 2D culture. Our approach of optimizing hAD-MSC hepatic differentiation could provide a potential solution to the challenges such as hepatocyte transplantation or the establishment of human physiologically relevant liver models in vitro.

Abstract
UNLABELLED : The development of liver cell transplantation (LCT), considered a major biotechnological breakthrough, was intended to provide more accessible treatments for liver disease patients. By preserving the native recipient liver and decreasing hospitalization time, this innovative approach has progressively gained interest among clinicians. LCT initially targets inborn errors of liver metabolism, enabling the compensation of deficient metabolic functions for up to 18 months post-transplantation, supporting its use at least as a bridge to transplantation. The rigorous clinical development and widespread use of LCT depends strongly on controlled and consistent clinical trial data, which may help improve several critical factors, including the standardization of raw biological material and immunosuppression regimens. Substantial effort has also been made in defining and optimizing the most efficient cell population to be transplanted in the liver setting. Although isolated hepatocytes remain the best cell type, showing positive clinical results, their widespread use is hampered by their poor resistance to both cryopreservation and in vitro culture, as well as ever-more-significant donor shortages. Hence, there is considerable interest in developing more standardized and widely accessible cell medicinal products to improve engraftment permanency and post-cell transplantation metabolic effects. SIGNIFICANCE In this therapeutic approach to liver disease, new solutions are being designed and evaluated to bypass the documented limitations and move forward toward wide clinical use. Future developments also require a deep knowledge of regulatory framework to launch specific clinical trials that will allow clear assessment of cell therapy and help patients with significant unmet medical needs.

Abstract
Techniques for producing decellularized scaffolds for use in liver tissue engineering are emerging as promising methods for tissue reconstruction. In this article, the authors present an overview of liver decellularization methods developed and applied in recent years. These include the widespread use of various perfusion methods for the generation of a 3D scaffold, which may function as a template for either cell recellularization or direct biological application. The authors evaluate methods for scaffold production and explore some factors that may affect the decellularization process. In addition to tissue engineering, this overview includes a description of other potential applications for a decellularized liver scaffold. The authors also introduce the concept of fabrication of fragile biomaterial architecture and finally review the cell types applied to liver scaffold engineering.

Abstract
Mitochondrial biogenesis and metabolism have recently emerged as important actors of stemness and differentiation. On the one hand, the differentiation of stem cells is associated with an induction of mitochondrial biogenesis and a shift from glycolysis toward oxidative phosphorylations (OXPHOS). In addition, interfering with mitochondrial biogenesis or function impacts stem cell differentiation. On the other hand, some inverse changes in mitochondrial abundance and function are observed during the reprogramming of somatic cells into induced pluripotent stem cells (iPSCs). Yet although great promises in cell therapy might generate better knowledge of the mechanisms regulating the stemness and differentiation of somatic stem cells (SSCs)-which are preferred over embryonic stem cells (ESCs) and iPSCs because of ethical and safety considerations-little interest was given to the study of their mitochondria. This study provides a detailed characterization of the mitochondrial biogenesis occurring during the hepatogenic differentiation of bone marrow-mesenchymal stem cells (BM-MSCs). During the hepatogenic differentiation of BM-MSCs, an increased abundance of mitochondrial DNA (mtDNA) is observed, as well as an increased expression of several mitochondrial proteins and biogenesis regulators, concomitant with increased OXPHOS activity, capacity, and efficiency. In addition, opposite changes in mitochondrial morphology and in the abundance of several OXPHOS subunits were found during the spontaneous dedifferentiation of primary hepatocytes. These data support reverse mitochondrial changes in a different context from genetically-engineered reprogramming. They argue in favor of a mitochondrial involvement in hepatic differentiation and dedifferentiation.

Abstract
Menstrual blood has been introduced as an easily accessible and refreshing stem cell source with no ethical consideration. Although recent works have shown that menstrual blood stem cells (MenSCs) possess multi lineage differentiation capacity, their efficiency of hepatic differentiation in comparison to other stem cell resources has not been addressed so far. The aim of this study was to investigate hepatic differentiation capacity of MenSCs compared to bone marrow-derived stem cells (BMSCs) under protocols developed by different concentrations of hepatocyte growth factor (HGF) and oncostatin M (OSM) in combination with other components in serum supplemented or serum-free culture media. Such comparison was made after assessment of immunophenotye, trans-differentiation potential, immunogenicity and tumorigeicity of these cell types. The differential expression of mature hepatocyte markers such as albumin (ALB), cytokeratin 18 (CK-18), tyrosine aminotransferase and cholesterol 7 alpha-hydroxylase activities (CYP7A1) at both mRNA and protein levels in differentiating MenSCs was significantly higher in upper concentration of HGF and OSM (P1) compared to lower concentration of these factors (P2). Moreover, omission of serum during differentiation process (P3) caused typical improvement in functions assigned to hepatocytes in differentiated MenSCs. While up-regulation level of ALB and CYP7A1 was higher in differentiated MenSCs compared to driven BMSCs, expression level of CK-18, detected level of produced ALB and glycogen accumulation were lower or not significantly different. Therefore, based on the overall comparable hepatic differentiation ability of MenSCs with BMSCs, and also accessibility, refreshing nature and lack of ethical issues of MenSCs, these cells could be suggested as an apt and safe alternative to BMSCs for future stem cell therapy of chronic liver diseases.

Abstract
Mesenchymal stem cells (MSCs) have emerged as an attractive candidate for cell therapy applications. In the prior decade, many animal studies have demonstrated that MSCs are therapeutically beneficial for the treatment of liver disease. The carbon tetrachloride (CCl4)-induced acute hepatitis model has been the most widely used model in these studies. Our group has utilized the CCl4-induced mouse hepatitis model to study the therapeutic potential of human adipose tissue-derived MSCs (hADSCs). We have demonstrated that systemically administered hADSCs engrafted into the damaged liver and promoted tissue repair. This phenomenon likely reflected the paracrine effects of the administered hADSCs. In this chapter, we describe a method to evaluate the therapeutic efficacy of the systemic administration of hADSCs in the CCl4-induced mouse model of acute hepatitis.

Abstract
Our objective is to control the reconstitution of liverlike tissues at extrahepatic sites using hepatic progenitor cells (HPCs) andin vitropreculture prior to transplantation. We prepared cell-based hybrid grafts by culturing HPCs isolated from fetal E14.5 mouse livers on biodegradable, highly porous 3-dimensional poly-L-lactic acid (PLLA) scaffolds for 1 week in basal medium (the basal condition) or 10 mM nicotinamide (NA) and 1% dimethyl sulfoxide (DMSO) supplemented conditions (the ND-positive condition) prior to implantation. Sections of hybrid grafts cultured for 1 week showed that HPCs grew and spread on the surface of scaffolds under both basal and ND (+) conditions. Most of these cells were albumin (+) and CK18 (+). CK19 (+) cells were also present under the basal condition but not the ND (+) condition. Cultured hybrid grafts were implanted into the mesenteric leaves of mice and removed after 1 month. Transplanted tissues cultured under the basal condition consisted of albumin (+) hepatocyte-like and CK19 (+) biliary epithelial cell (BEC)-like cells organized in duct-like structures. In contrast, integrated tissues cultured under the ND (+) condition alone had differentiated albumin (+) hepatocyte-like cells and were relatively larger than those under the basal condition. Hepatocyte-like cells of transplanted hybrid grafts cultured under both conditions were periodic acid-Schiff (PAS) staining-positive and expressed transcription factors, hepatocyte nuclear factor (HNF) 4 and CCAAT/enhancer-binding protein (C/EBP) α. These findings suggest that combining progenitor cells andin vitropreculture may potentially regulate liverlike tissues at extrahepatic sites.

Abstract
Adult stem cells have shown fantastic regenerative potential as the cellular components of biomaterial mediated tissue engineering. Realising the biomedical potential of human adult stem cells (hASCs) however will require delivery in an ultra- purified format, without competing cells which may mediate inflammation, fibrosis or tumorigenesis. Purifying ASCs involves exhuming cells from primary tissue using immunoaffinity; which isolates pure populations with the complication of retained immunoglobulin (Ig); the clinical impact of which is currently not known. One of the negative outcomes of retained surface Ig is exacerbation of inflammation by leucocyte Fc receptor (FcR) activation, with consequences ranging from inflammatory cytokine and ROS release to chronic inflammation. The balance of ROS within a tissue will impact the efficacy of a stem cell therapy as ROS play an important role in stem cell self renewal and differentiation. In this study we utilised a chemiluminescent monitoring technique based on a ROS excitable photoprotein Pholasin, to quantify leucocyte ROS production in response to xenogeneic and recombinant human Ig of varying class and isotype with applications in stem cell selection. We were able to demonstrate inter-class differences in leucocyte ROS response to Ig which also varied between donors. This study highlighted the potential for utilising this technique for personalisation of autologous ASC therapies. This would allow clinicians to perform a rapid pre-operative screen to maximise the probability for success of an ASC intervention based on cell isolation using an Ig most appropriate for a specific patient.

Abstract
Hepatic progenitor cells (HPCs) are a potential cell source for liver cell
transplantation but do not function like mature liver cells. We sought an
effective and reliable method to induce HPC maturation. An immortalized HP14.5
albumin promoter-driven Gaussian luciferase (ALB-GLuc) cell line was established
from HPCs isolated from fetal mouse liver of post coitus day 14.5 mice to
investigate the effect of induction factors on ALB promoter. HP14.5 parental
cells were cultured in DMEM with different combinations of 2% horse serum (HS),
0.1 µM dexamethasone (DEX), 10 ng/mL hepatic growth factor (HGF), and/or 20
ng/mL fibroblast growth factor 4 (FGF4). Trypan blue and crystal violet staining
were used to assess cell proliferation with different induction conditions.
Expression of hepatic markers was measured by semi-quantitative RT-PCR, Western
blot, and immunofluorescence. Glycogen storage and metabolism were detected by
periodic acid-Schiff and indocyanine green (ICG) staining. GLuc activity
indicated ALB expression. The combination of 2% HS+0.1 µM Dex+10 ng/mL HGF+20
ng/mL FGF4 induced the highest ALB-GLuc activity. Cell proliferation decreased
in 2% HS but increased by adding FGF4. Upon induction, and consistent with
hepatocyte development, DLK, AFP, and CK19 expression decreased, while ALB,
CK18, and UGT1A expression increased. The maturity markers tyrosine
aminotransferase and apolipoprotein B were detected at days 3 and 6
post-induction, respectively. ICG uptake and glycogen synthesis were detectable
at day 6 and increased over time. Therefore, we demonstrated that HPCs were
induced to differentiate into functional mature hepatocytes in
vitro, suggesting that factor-treated HPCs may be further explored
as a means of liver cell transplantation.

Abstract
In recent years, the advantages of menstrual blood-derived stem cells (MenSCs), such as minimal ethical considerations, easy access and high proliferative ability, have inspired scientists to investigate the potential of MenSCs in cell therapy of different diseases. In order to characterize the potency of these cells for future cell therapy of liver diseases, we examined the potential of MenSCs to differentiate into hepatocytes, using different protocols. First, the immunophenotyping properties and potential of MenSCs to differentiate into osteoblasts, adipocytes and chondrocytes were evaluated. Thereafter, the differentiation protocols developed by two concentrations of hepatocyte growth factor (HGF) and oncostatin M (OSM), in combination with other components in serum-supplemented or serum-free culture media, were also investigated. The sequential differentiation was monitored by real-time PCR, immunostaining and functional assays. Our primary data revealed that the isolated MenSCs exhibited mesenchymal stem cell markers in parallel to OCT-4 as an embryonic marker. Regardless of differentiation procedures, the developed cells expressed mature hepatocyte markers, such as albumin, tyrosine aminotransferase and cytokeratin-18 at the mRNA and protein levels. They also showed functional properties of hepatocytes, including albumin secretion, glycogen storage and cytochrome P450 7A1 expression. However, the degree of differentiation was dependent on the concentrations of HGF and OSM. Indeed, omission of serum during the differentiation process caused typical improvement in hepatocyte-specific functions. This study is a novel report demonstrating the differentiation potential of MenSCs into hepatocyte-like cells. We recommend a complementary serum-free differentiation protocol for enrichment of in vitro production of functional MenSC-derived hepatocyte-like cells that could lead to a major step toward applied stem cell therapy of chronic liver diseases.

Abstract
Extracellular vesicles (EVs), membrane vesicles that are secreted by a variety of mammalian cell types, have been shown to play an important role in intercellular communication. The contents of EVs, including proteins, microRNAs, and mRNAs, vary according to the cell type that secreted them. Accordingly, researchers have demonstrated that EVs derived from various cell types play different roles in biological phenomena. Considering the ubiquitous presence of mesenchymal stem cells (MSCs) in the body, MSC-derived EVs may take part in a wide range of events. In particular, MSCs have recently attracted much attention due to the therapeutic effects of their secretory factors. MSC-derived EVs may therefore provide novel therapeutic approaches. In this review, we first summarize the wide range of functions of EVs released from different cell types, emphasizing that EVs echo the phenotype of their parent cell. Then, we describe the various therapeutic effects of MSCs and pay particular attention to the significance of their paracrine effect. We then survey recent reports on MSC-derived EVs and consider the therapeutic potential of MSC-derived EVs. Finally, we discuss remaining issues that must be addressed before realizing the practical application of MSC-derived EVs, and we provide some suggestions for enhancing their therapeutic efficiency.

Abstract
Alzheimer's disease (AD) is characterized by the accumulation of β-amyloid peptide (Aβ) in the brain because of an imbalance between Aβ production and clearance. Neprilysin (NEP) is the most important Aβ-degrading enzyme in the brain. Thus, researchers have explored virus-mediated NEP gene delivery. However, such strategies may entail unexpected risks, and thus exploration of a new possibility for NEP delivery is also required. Here, we show that human adipose tissue-derived mesenchymal stem cells (ADSCs) secrete exosomes carrying enzymatically active NEP. The NEP-specific activity level of 1 μg protein from ADSC-derived exosomes was equivalent to that of ~ 0.3 ng of recombinant human NEP. Of note, ADSC-derived exosomes were transferred into N2a cells, and were suggested to decrease both secreted and intracellular Aβ levels in the N2a cells. Importantly, these characteristics were more pronounced in ADSCs than bone marrow-derived mesenchymal stem cells, suggesting the therapeutic relevance of ADSC-derived exosomes for AD.

Abstract
BACKGROUND Cell based therapies are required now to meet the critical care needs of paediatrics and healthy ageing in an increasingly long-lived human population. Repair of compromised tissue by supporting autologous regeneration is a life changing objective uniting the fields of medical science and engineering. Adipose stem cells (adSCs) are a compelling candidate for use in cell based medicine due to their plasticity and residence in numerous tissues. Adipose found in all animals contains a relatively high concentration of stem cells and is easily isolated by a minimally invasive clinical intervention; such as liposuction. METHODS This study utilised primary rat adipose to validate a novel strategy for selecting adult stem cells. Experiments explored the use of large, very dense cell-specific antibody loaded isolation beads (diameter 5x-10x greater than target cells) which overcome the problem of endocytosis and have proved to be very effective in cell isolation from minimally processed primary tissue. The technique also benefited from pH mediated release, which enabled elution of captured cells using a simple pH shift. RESULTS Large beads successfully captured and released adSCs from rat adipose, which were characterised using a combination of microscopy, flow cytometry and PCR. The resultant purified cell population retains minimal capture artefact facilitating autologous reperfusion or application in in vitro models. CONCLUSION Although evidenced here for adSCs, this approach provides a technological advance at a platform level; whereby it can be applied to isolate any cell population for which there is a characterised surface antigen.

Abstract
Liver transplantation is currently the most efficacious treatment for end-stage liver diseases. However, one main problem with liver transplantation is the limited number of donor organs that are available. Therefore, liver tissue engineering based on cell transplantation that combines materials to mimic the liver is under investigation with the goal of restoring normal liver functions. Tissue engineering aims to mimic the interactions among cells with a scaffold. Particular materials or a matrix serve as a scaffold and provide a three-dimensional environment for cell proliferation and interaction. Moreover, the scaffold plays a role in regulating cell maturation and function via these interactions. In cultures of hepatic lineage cells, regulation of cell proliferation and specific function using biocompatible synthetic, biodegradable bioderived matrices, protein-coated materials, surface-modified nanofibers, and decellularized biomatrix has been demonstrated. Furthermore, beneficial effects of addition of growth factor cocktails to a flow bioreactor or coculture system on cell viability and function have been observed. In addition, a system for growing stem cells, liver progenitor cells, and primary hepatocytes for transplantation into animal models was developed, which produces hepatic lineage cells that are functional and that show long-term proliferation following transplantation. The major limitation of cells proliferated with matrix-based transplantation systems is the high initial cell loss and dysfunction, which may be due to the absence of blood flow and the changes in nutrients. Thus, the development of vascular-like scaffold structures, the formation of functional bile ducts, and the maintenance of complex metabolic functions remain as major problems in hepatic tissue engineering and will need to be addressed to enable further advances toward clinical applications.

Abstract
Tissue engineering is a clinically driven field and has emerged as a potential alternative to organ transplantation. The cornerstone of successful tissue engineering rests upon two essential elements: cells and scaffolds. Recently, it was found that stem cells have unique capabilities of self-renewal and multilineage differentiation to serve as a versatile cell source, while nanomaterials have lately emerged as promising candidates in producing scaffolds able to better mimic the nanostructure in natural extracellular matrix and to efficiently replace defective tissues. This article, therefore, reviews the key developments in tissue engineering, where the combination of stem cells and nanomaterial scaffolds has been utilized over the past several years. We consider the high potential, as well as the main issues related to the application of stem cells and nanomaterial scaffolds for a range of tissues including bone, cartilage, nerve, liver, eye etc. Promising in vitro results such as efficient attachment, proliferation and differentiation of stem cells have been compiled in a series of examples involving different nanomaterials. Furthermore, the merits of the marriage of stem cells and nanomaterial scaffolds are also demonstrated in vivo, providing early successes to support subsequent clinical investigations. This progress simultaneously drives mechanistic research into the mechanotransduction process responsible for the observations in order to optimize the process further. Current understanding is chiefly reported to involve the interaction of stem cells and the anchoring nanomaterial scaffolds by activating various signaling pathways. Substrate surface characteristics and scaffold bulk properties are also reported to influence not only short term stem cell adhesion, spreading and proliferation, but also longer term lineage differentiation, functionalization and viability. It is expected that the combination of stem cells and nanomaterials will develop into an important tool in tissue engineering for the innovative treatment of many diseases.

Abstract
Hepatocyte transplantation utilizing induced pluripotent stem cells (iPSCs) or embryonic stem cells (ESCs) has been expected to provide an alternative to liver transplantation. However, it remains uncertain precisely which cell type is the best suited for cell transplantation. In particular, it is unclear whether mature hepatocytes, which have sufficient liver function, or immature hepatic progenitor cells, which have a higher proliferative capacity, will provide a better outcome. The main objective of this study was to investigate the therapeutic efficacy of the transplantation of hepatocytes at various differentiation stages. We utilized transgenic mice that expressed diphtheria toxin (DT) receptors under the control of an albumin enhancer/promoter. ESC-derived endodermal cells, fetal hepatocytes, and adult hepatocytes were transplanted into these mice with experimentally induced lethal acute liver injury caused by DT administration. The transplanted cells were marked by enhanced green fluorescent protein. We evaluated their effects on survival. At 35 days after transplantation, the survival rate of the adult hepatocyte-transplanted group (8/20, 40%) was significantly improved in comparison to that of the sham-operated group (2/25, 8%), the fetal hepatocyte-transplanted group (1/20, 5%), and the ESC-derived endodermal cell-transplanted group (0/21, 0%). The adult hepatocytes proliferated in the recipient livers and replaced a large part of their parenchyma. The transplantation of adult hepatocytes for acute liver failure significantly improved the survival rate in comparison to that of transplantation of immature cells, thus suggesting that ESCs and iPSCs should be differentiated into mature hepatocytes before cell transplantation for acute liver failure.

Abstract
Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells have an enormous potential; however, their potential clinical application is being arrested due to various limitations such as teratoma formation followed by tumorigenesis, emergent usage, and the quality control of cells, as well as safety issues regarding long-term culture are also delaying their clinical application. In addition, human ES cells have two crucial issues: immunogenicity and ethical issues associated with their clinical application. The efficient generation of human iPS cells requires gene transfer, yet the mechanism underlying pluripotent stem cell induction has not yet been fully elucidated. Otherwise, although human adult regenerative cells including mesenchymal stem cells have a limited capacity for differentiation, they are nevertheless promising candidates for tissue regeneration in a clinical setting. This review highlights the use of regenerative cells for transplantation in hepatic failure.

Abstract
There is a great interest in the development of functional hepatocytes in vitro from different types of stem cells. Multipotential mesenchymal stem cells (MSC) compose a great source for stem cell based therapy, especially, because they can be obtain from patients own tissues, sidestepping immunocompatibility and ethical issues. Among MSCs from different sources, adipose-tissue-derived mesenchymal stem cells (AT-MSCs) are very promising because of their high accessibility, proliferation ability, potentiality, and immunocompatibility.AT-MSCs can be easily isolated from stroma vascular fraction (SVF) of adipose tissue. They represent a heterogeneous population of cells. The precise AT-MSCs's marker profile has not been defined yet; therefore, it is still not obvious how to purify these heterogeneous fraction of cells. We postulate that one of the markers defining MSC provenance is CD105 (endoglin).Therefore, we have sorted CD105(+) fraction of AT-MSCs, expanded them, and differentiated toward hepatic-like cells. In order to check their potentiality, we have firstly differentiated sorted CD105(+) AT-MSCs toward mesoderm lineages, using commercialized protocols.We have shown here, that pure CD105(+) AT-MSCs fraction revealed higher homogeneity and differentiation potential toward adipogenic, osteogenic, and chondrogenic lineages and highly inducible into the hepatogenic lineage.Generated (by using our hepatic differentiation protocol) CD105(+) AT-MSCs-derived hepatic-like cells expressed hepatocyte markers, enzymes, and functions.

Abstract
Clones of hepatocyte-like cells were reproducibly generated from human mesenchymal stem cells immortalized with a combined transduction of both Bmi-1 and TERT genes. These hepatocyte-like cells contained selective markers and several functional properties of hepatocytes, yet still carried proliferative potential. These cells had cuboidal morphology and arranged themselves as cord-like structure in culture. The cloned cells deposited glycogen and actively synthesized albumin. The basal expressions of CYP450 isozymes was observed, albeit only 10-20% that of primary hepatocytes. These expressions were promptly increased upon the addition of rifampicin, a known enzyme inducer. These hepatocyte-like cells may serve as a close alternative to the use of primary hepatocytes for in vitro studies.

Abstract
BACKGROUND The strenuous procurement of cultured human hepatocytes and their short lives have constrained the cell culture model of cytochrome P450 (CYP450) induction, xenobiotic biotransformation, and hepatotoxicity. The development of continuous non-tumorous cell line steadily containing hepatocyte phenotypes would substitute the primary hepatocytes for these studies. RESULTS The hepatocyte-like cells have been developed from hTERT plus Bmi-1-immortalized human mesenchymal stem cells to substitute the primary hepatocytes. The hepatocyte-like cells had polygonal morphology and steadily produced albumin, glycogen, urea and UGT1A1 beyond 6 months while maintaining proliferative capacity. Although these hepatocyte-like cells had low basal expression of CYP450 isotypes, their expressions could be extensively up regulated to 80 folds upon the exposure to enzyme inducers. Their inducibility outperformed the classical HepG2 cells. CONCLUSION The hepatocyte-like cells contained the markers of hepatocytes including CYP450 isotypes. The high inducibility of CYP450 transcripts could serve as a sensitive model for profiling xenobiotic-induced expression of CYP450.

Abstract
Stem cells can be obtained from women's menstrual blood derived from the endometrium. The cells display stem cell markers such as Oct-4, SSEA-4, Nanog, and c-kit (CD117), and have the potent ability to differentiate into various cell types, including the heart, nerve, bone, cartilage, and fat. There has been no evidence of teratoma, ectopic formation, or any immune response after transplantation into an animal model. These cells quickly regenerate after menstruation and secrete many growth factors to display recurrent angiogenesis. The plasticity and safety of the acquired cells have been demonstrated in many studies. Menstrual blood-derived stem cells (MenSCs) provide an alternative source of adult stem cells for research and application in regenerative medicine. Here we summarize the multipotent properties and the plasticities of MenSCs and other endometrial stem cells from recent studies conducted both in vitro and in vivo.

Abstract
BACKGROUND Ischemia-reperfusion (I/R) injury associated with living donor liver transplantation impairs liver graft regeneration. Mesenchymal stem cells (MSCs) are potential cell therapeutic targets for liver disease. In this study, we demonstrate the impact of MSCs against hepatic I/R injury and hepatectomy. METHODOLOGY/PRINCIPAL FINDINGS We used a new rat model in which major hepatectomy with I/R injury was performed. Male Lewis rats were separated into two groups: an MSC group given MSCs after reperfusion as treatment, and a Control group given phosphate-buffered saline after reperfusion as placebo. The results of liver function tests, pathologic changes in the liver, and the remnant liver regeneration rate were assessed. The fate of transplanted MSCs in the luciferase-expressing rats was examined by in vivo luminescent imaging. The MSC group showed peak luciferase activity of transplanted MSCs in the remnant liver 24 h after reperfusion, after which luciferase activity gradually declined. The elevation of serum alanine transaminase levels was significantly reduced by MSC injection. Histopathological findings showed that vacuolar change was lower in the MSC group compared to the Control group. In addition, a significantly lower percentage of TUNEL-positive cells was observed in the MSC group compared with the controls. Remnant liver regeneration rate was accelerated in the MSC group. CONCLUSIONS/SIGNIFICANCE These data suggest that MSC transplantation provides trophic support to the I/R-injured liver by inhibiting hepatocellular apoptosis and by stimulating regeneration.

Abstract
It has been demonstrated that several types of somatic stem cells have the remarkable capacity to differentiate into other types of tissues. However, the promise of keratinocyte stem cells seems slim for generating nonepidermal tissues. Using our recently developed acclimatization induction strategy, we demonstrate the multipotency of adult human undifferentiated keratinocytes (UKs). The UKs were isolated from the basal layer of adult human foreskin and cultured in Epilife medium, which allows for the growth of only keratin-positive keratinocytes, promotes high proliferation of UKs, and prevents their differentiation. Induction of the UKs by either serum or lineage-committed medium only produce differentiated epidermal cells. Hence, serum or lineage-committed medium was added to Epilife to acclimate UKs to differentiate to other cell types. Unexpectedly, serum acclimatization can induce UKs to produce a large number of smooth muscle cells and fewer of adipocytes and neurocytes within 3 weeks. In contrast, except for the terminally differentiated epidermal cells, committed acclimatization can induce UKs to differentiate exclusively into the adipocytic, myogenic, or neurogenic lineages. These data indicate that human UKs represent a novel multipotent adult stem cell, and suggest that they may provide an accessible, therapeutically promising cell source for regenerative medicine.

Abstract
Stromal cells residing in murine fetal livers have the ability to promote the hepatic maturation of murine embryonic stem cells (ESCs) and hepatic progenitor cells (HPCs) 3848 in vitro. These stromal cells were isolated as the CD49f(+/-)CD45(-)Thy1(+)gp38(+) cell fraction. The present study established a murine fetal liver stromal cell line that induced hepatic maturation in mouse ESCs and HPCs. A transgene containing a temperature-sensitive SV40 large T antigen was transfected into the primary fetal liver stromal cells. These immortalized cells, which were named as the gp38-positive and Thy1-positive murine liver stromal (MLSgt) cells, induced both mouse ESCs and HPCs to differentiate into mature hepatocyte-like cells using a coculture method. Since MLSgt is not a cloned cell line, one clone, MLSgt20, was selected as a line with the characteristic to induce hepatic differentiation, which was comparable to its parental stromal cells. The ESC-derived endoderm cells cocultured with the MLSgt20 cells expressed mature hepatocyte-specific gene markers, including glucose-6-phosphatase, tyrosine aminotransferase, tryptophan 2,3-dioxgenase, and cytochrome P450 (CYP1a1, Cyp1b1, Cyp1a2, and Cyp3a11). In addition, these cells also exhibited hepatic functions, such as glycogen storage and ammonia metabolism. Transmission electron microscopy showed that the cocultured ESCs expressed the morphologic features of mature hepatocytes. In conclusion, a cell line was established that has the characteristic to promote the hepatic maturation of mouse ESCs and HPCs by a coculture method.

Abstract
Liver transplants represent the only way to treat patients suffering from terminal liver failure, but they are associated with numerous problems, including a chronic shortage of donors, high cost, rejection, and side effects for the donor. It is anticipated that regenerative medicine will provide an alternative to liver transplants for such patients. Regenerative medicine refers to the academic field of eliciting the inherent capacity of organisms for self-regeneration to the greatest possible extent in order to develop new methods of treatment for intractable disorders. From this perspective, much is expected from the use of human embryonic stem cells (ES cells) or induced pluripotent stem cells (iPS cells), and the vigorous development of technology to induce the differentiation of such stem cells into cells possessing hepatic functions is underway. Clinical applications of these human stem cells, however, have yet to reach even the earliest stages of implementation. Facing off against these versatile ES cells are stem cells derived from somatic cells present within organisms, which are attracting attention owing to their superiority in terms of ethics and safety, with many research institutes now in the process of elucidating the details of stem cell separation and identification as well as their plasticity and pluripotency. Bone marrow cells are the best-known somatic-cell-derived stem cells, but the use of mesenchymal stem cells (MSCs) found in adipose tissue has also recently attracted attention. This paper will review the differentiation ability and mechanisms of these various stem cell types to hepatocytes and their application to liver regeneration and the future outlook.

Abstract
Our research group investigates whether human mononuclear cells isolated from umbilical cord blood (HUCBM cells) might be valuable in hepatic regenerative medicine. We recently demonstrated that HUCBM cell transplantation improves histological alterations and function of the liver in rats with acute liver damage induced by D-galactosamine. In the present study, HUCBM cells were transplanted into rats with thioacetamide (TAA)-induced liver cirrhosis, an experimental model that generates an intense fibrosis and mimics the histological and biochemical alterations found in the human disease. HUCBM transplantation had no effect on hepatic histology of cirrhotic animals. In contrast, analysis of plasma albumin and total bilirubin, liver damage markers, revealed a harmful effect of HUCBM cell transplantation in our experimental model of liver cirrhosis. Significantly higher plasma urea concentrations, marker of renal function, were observed in the cirrhotic and control rats intraportally injected with HUCBM cells than in those not receiving this therapy. Histological study revealed tubular and glomerular lesions in kidneys of cirrhotic animals transplanted with HUCBM cells. The glomeruli appeared ischemic, and the tubules showed a severe involvement that included peripheral asymmetric vacuolization and disappearance of the tubular lumen. Taken together, the histological and biochemical data suggest that the cirrhotic rats subjected to HUCBM cell therapy developed a hepatorenal syndrome.

Abstract
Recent findings demonstrated that stem cells could be harvested from a patient and used to repair his or her own damaged liver. Additionally, stem cells may be manipulated in vitro to induce hepatic differentiation. The current study aims to determine the differentiation efficacy of various liver-specific factors (hepatocyte growth factor, Insulin-Transferrin-Selenium, dexamethasone, and nicotinamide) used for stem cell differentiation into hepatocyte-like cells. Human mesenchymal stem cells were exposed to different media containing these compounds added individually or in various combinations. Hepatic differentiation was assessed via quantitative reverse transcription-polymerase chain reaction and immunocytochemical staining for stemness or liver-specific genes and proteins, including albumin, cytokeratins 18 and 19, HepPar-1, alpha-fetoprotein, and nestin. In addition, functional tests for glycogen storage, urea production, glucose, and albumin synthesis were also performed. The expression profiles of albumin, alpha-fetoprotein, and cytokeratin 19 demonstrated that when hepatocyte growth factor, nicotinamide, or dexamethasone were added individually, incomplete hepatocyte differentiation was achieved; the obtained cell populations contained progenitors that expressed both hepatic (albumin) and biliary (cytokeratin 19) markers, as well as alpha-fetoprotein. Hepatocyte growth factor and nicotinamide were the factors with the most hepatogenic potential. When all factors were added to the culture, cells exhibited features that closely resembled human adult hepatocytes as determined by their gene expression patterns (albumin, HepPar-1, and alpha-fetoprotein, but not cytokeratin 19) and functional testing. These cells with hepatic function may become important tools for liver transplant procedures, liver development studies, and pharmacologic research.

Abstract
Fibroblast growth factors (FGFs) were initially recognized as fibroblast-specific growth factor, and it is now apparent that these growth factors regulate multiple biological functions. The diversity of FGFs function is paralleled by the emerging diversity of interactions between FGF ligands and their receptors. FGF-4 is a member of the FGF superfamily and is a mitogen exhibiting strong action on numerous different cell types. It plays a role in various stages of development and morphogenesis, as well as in a variety of biological processes. Recent studies reveal the molecular mechanisms of FGF-4 gene regulation in mammalian cells, which is involved in the developmental process. Furthermore, FGF-4 also acts on the regulation of proliferation and differentiation in embryonic stem cells and tissue stem cells. In this review, we focus on the diverse biological functions of FGF-4 in the developmental process and also discuss its putative roles in stem cell biology.

Abstract
Mesenchymal stem cells (MSCs), largely present in the adult human body, represent an attractive tool for the establishment of a stem cell-based therapy for liver diseases. Recently, the therapeutic potential and immunomodulatory activity of MSCs have been revealed. Adipose tissue-derived mesenchymal stem cells (AT-MSCs), so-called adipose-derived stem cells or adipose stromal cells, because of their high accessibility with minimal invasiveness, are especially attractive in the context of future clinical applications. The goal of the present study was to evaluate the therapeutic potential of AT-MSCs by their transplantation into nude mice with CCl(4)-caused liver injury. We observed that after transplantation, AT-MSCs can improve liver functions, which we verified by changes in the levels of biochemical parameters. Ammonia, uric acid, glutamic-pyruvic transaminase, and glutamic-oxaloacetic transaminase concentrations returned to a nearly normal level after AT-MSC transplantation. These results raised the question of how AT-MSCs can achieve this. To discover the possible mechanisms involved in this therapeutic ability of AT-MSCs, in vitro production of cytokines and growth factors was analyzed and compared with MSCs from bone marrow (BM-MSCs) and normal human dermal fibroblasts (NHDFs). As a result we observed that AT-MSCs secrete interleukin 1 receptor alpha (IL-1Ralpha), IL-6, IL-8, granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemotactic protein 1, nerve growth factor, and hepatocyte growth factor in a volume higher than both BM-MSCs and NHDFs. Thus, our findings suggest that AT-MSCs may account for their broad therapeutic efficacy in animal models of liver diseases and in the clinical settings for liver disease treatment. Disclosure of potential conflicts of interest is found at the end of this article.
