Introduction:Mesenchymal stromal/stem cells (MSCs) derived from fat tissue are an encouraging tool for regenerative medicine. They share properties similar to the bone marrow-derived MSCs, but the amount of MSCs per gram of fat tissue is 500x higher. The fat tissue can easily be digested by collagenase, releasing a heterogeneous cell fraction called stromal vascular fraction (SVF) which contains a variable amount of stromal/stem cells. In Europe, cell products like the SVF derived from fat tissue are considered advanced therapy medicinal product (ATMPs). As a consequence, the manufacturing process has to be approved via GMP-compliant process validation. The problem of the process validation for SVF is the heterogeneity of this fraction.
Methods: Here, we modified existing purification strategies by adding an additional plastic adherence incubation of maximal 20 hours after SVF isolation. The resulting cell fraction was characterized and compared to SVF as well as cultivated adipose-derived stromal/stem cells (ASCs) with respect to viability and cell yield, the expression of surface markers, differentiation potential and cytokine expression.
Results: Short-term incubation significantly reduced the heterogeneity of the resulting cell fraction compared to SVF. The cells were able to differentiate into adipocytes, chondrocytes, and osteoblasts. More importantly, they expressed trophic proteins which have been previously associated with the beneficial effects of MSCs. Furthermore, GMP compliance of the production process described herein was acknowledged by the national regulatory agencies (DE_BB_01_GMP_2017_1018).
Conclusion: Addition of a short purification-step after the SVF isolation is a cheap and fast strategy to isolate a homogeneous uncultivated GMP-compliant cell fraction of ASCs.

Abstract
The role of mesenchymal stem cells (MSCs) in cellular therapy is well recognized in this work. MSCs have advantages of high proliferation, clone formation, multi-lineage differentiation and immunosuppression. Furthermore, adipose-resident MSCs (ADSCs) are extensively employed due to its advantages of abundant source, low cost and simple operation. Many researchers have emphasized the role of adipose-resident MSCs in the development of therapies for liver injury, but few attentions were paid on the use of induced functional hepatocytes. Therefore, in this work the role of adipose-resident MSCs induced functional hepatocytes was mainly investigated. The function of induced hepatocytes by ELISA and the induction rate was confirmed by flow cytometry and evaluated by experimental observations. The induced hepatocytes were firstly transplanted into CCl4-caused liver damage ICR mice by tail vein. After transplantation, both liver fibrosis and function could be improved by hepatocytes, which were examined through histology, immunofluorescence staining, serum profile and biochemical parameters levels. The production of cytokines was then compared with normal mice and injury mice to explore the therapeutic mechanisms of hepatocytes. Finally, the secretions of TGF-β1, IL-6 and IL-10 in hepatocytes transplanted mice were determined and found to be higher than that of the normal and injury mice. The hepatocytes derived from ADSCs were proven to have a great significance in the therapeutic efficacy and clinical settings of liver disease animal models.

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
UNLABELLED Functional pluripotent characteristics have been observed in specific subpopulations of hepatic cells that express some of the known cholangiocyte markers. Although evidence indicates that specific cytokines, granulocyte macrophage colony-stimulating factors (GM-CSFs), and stem cell factors (SCFs) may be candidate treatments for liver injury, the role of these cytokines in intrahepatic biliary epithelium remodeling is unknown. Thus, our aim was to characterize the specific cytokines that regulate the remodeling potentials of cholangiocytes after 70% partial hepatectomy (PH). The expression of the cytokines and their downstream signaling molecules was studied in rats after 70% PH by immunoblotting and in small and large murine cholangiocyte cultures (SMCCs and LMCCs) by immunocytochemistry and real-time polymerase chain reaction (PCR). There was a significant, stable increase in SCF and GM-CSF levels until 7 days after PH. Real-time PCR analysis revealed significant increases of key remodeling molecules, such as S100 calcium-binding protein A4 (S100A4) and miR-181b, after SCF plus GM-CSF administration in SMCCs. SMCCs produced significant amounts of soluble and bound SCFs and GM-CSFs in response to transforming growth factor-beta (TGF-β). When SMCCs were incubated with TGF-β plus anti-SCF+GM-CSF antibodies, there was a significant decrease in S100A4 expression. Furthermore, treatment of SMCCs with SCF+GM-CSF significantly increased matrix metalloproteinases (MMP-2 and MMP-9) messenger RNA as well as miR-181b expression, along with a reduction of metalloproteinase inhibitor 3. Levels of MMP-2, MMP-9, and miR-181b were also up-regulated in rat liver and isolated cholangiocytes after PH. CONCLUSION Our data suggest that altered expression of SCF+GM-CSF after PH can contribute to biliary remodeling (e.g., post-transplantation) by functional deregulation of the activity of key signaling intermediates involved in cell expansion and multipotent differentiation.

Abstract
The liver is an organ consisting of the largest reticulo-endothelial cell network in the body and playing an important role in host defense against invading microorganisms. The organ is comprised of parenchymal cells and many different types of non-parenchymal cells, all of which play a significant role. Even biliary epithelial cells are not only the target in autoimmune liver diseases but also have central role in orchestrating several immune cells involved in both innate and acquired immunity. Tissue damage caused by various agents results in inflammation, necrosis, fibrosis, and, eventually, distortion of normal hepatic architecture, cirrhosis, and functional deterioration.

CD56 as a useful marker in the regenerative process of the histological progression of primary biliary cirrhosis. Eur J Gastroenterol Hepatol 2008; 20:837-42.

Abstract
OBJECTIVE Owing to recent contradicting results in the study of the regenerative process after hepatic injury in primary biliary cirrhosis, we investigated the use of CD56 in tissue repair during the histological progression of primary biliary cirrhosis. METHODS Fifty-three specimens were classified into Ludwig's stages (1-4) as follows: 14 specimens as stage 1, 23 as stage 2, 14 as stage 3, and two as stage 4. Immunohistochemical stain was performed for CD56. The cell types expressing the marker were morphologically analyzed to determine their origin. RESULTS In normal liver biliary epithelial cells (including the epithelium of terminal bile ducts and bile ductules), hepatocytes, and intermediate cells (features between hepatocytes and biliary cells, distributed in interface between hepatic parenchyma and portal tract) were CD56. In primary biliary cirrhosis specimens, biliary epithelial cells, hepatocytes, and intermediate cells were CD56 distributed as 10 out of 14 cases as stage 1 (71.43%), 18 out of 23 as stage 2 (78.26%), nine out of 14 as stage 3 (64.28%), and two out of two as stage 4 (100%). The total positive cases were 39 of 53 (73.58%). CD56 was expressed equally in all three types of cells. CONCLUSION These findings indicate that the consistent and uniform expression of CD56 in biliary epithelial cells, hepatocytes, and intermediate cells during hepatic injury in primary biliary cirrhosis is probably related to cellular damage and may be important in tissue regeneration. Furthermore, we cannot distinguish a specific cell type from the three above mentioned ones (biliary epithelial cells, hepatocytes, intermediate cells) as a putative stem cell in primary biliary cirrhosis.

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.
