Liver fibrogenesisis chronic tissue damage characterized by an extracellular ac-cumulation of fibrillar matrix associated with continuous degradation and remod-elling. This scientific review describes current concepts on the pathophysiology of liver fibrosis, inflammation asa fundamental concept of liver fibrosis, mechanistic concepts of liver fibrosis, the role of mesenchymal stem cells (MSC) in liver injury, the functional effects of MSC secretome, the advantages of secretome ther-apy, and the latest research developments on MSC. The role of MSCs has been proven in many liver fibrosis studies involving experimental animals. However, it still requires further research for safety and efficacy aspects.

The inflammatory response to chronic injury affects tissue regeneration and has become an important factor influencing the prognosis of patients. In previous stem cell treatments, it was revealed that stem cells not only have the ability for direct differentiation or regeneration in chronic tissue damage but also have a regulatory effect on the immune microenvironment. Stem cells can regulate the immune microenvironment during tissue repair and provide a good “soil” for tissue regeneration. In the current study, the regulation of immune cells by mesenchymal stem cells (MSCs) in the local tissue microenvironment and the tissue damage repair mechanisms are revealed. The application of the concepts of “seed” and “soil” has opened up new research avenues for regenerative medicine. Tissue engineering (TE) technology has been used in multiple tissues and organs using its biomimetic and cellular cell abilities, and scaffolds are now seen as an important part of building seed cell microenvironments. The effect of tissue engineering techniques on stem cell immune regulation is related to the shape and structure of the scaffold, the preinflammatory microenvironment constructed by the implanted scaffold, and the material selection of the scaffold. In the application of scaffold, stem cell technology has important applications in cartilage, bone, heart, and liver and other research fields. In this review, we separately explore the mechanism of MSCs in different tissue and organs through immunoregulation for tissue regeneration and MSC combined with 3D scaffolds to promote MSC immunoregulation to repair damaged tissues.

Abstract Abstract 4486 Objective To explore mechanism of Mesenchymal stem cells in treating Rheumatoid arthritis. Methods (1) MSCs were isolated from Bone marrow samples of Rheumatoid arthritis(RA)patients and purified by density gradient centrifagation and cultured in vitro. Morphology, immunophenotype, and proliferative property of bMSC and colony forming unit-fibroblast (CFU-F) were measured and analyzed. (2) In an in vitro co-culture system, MSCs were observed to modulate proliferation,activation, and maturation of T and B lymphocytes of Rheumatoid arthritis(RA)patients. The expression of IL-1?ATNF-a?ATGF-β were obviously changed.(3) Bone marrow- derived BMSCs of wistar rats were isolated and cultured in vitro routinely and the fourth passage as taken for identification of specific surface antigens by flowcytometry, then were labled with 5- BrdU in vitro. The model of collagen-induced arthritis (CIA) rats were established. 5- BrdU labled BMSCs were implanted through tail vein to model rats. At 4 weeks after BMSCs transplantation, immunohistochemical examinations were used to investigate BMSCs aggregate around the knee joints.and identify the contribution of bone marrow– derived cells to joints damage repair. Results (1) The culture expanded cells from RA patients presented a typical fibroblast-like morphology. Cells were positive for SH2(CD105),CD71,and CD44, but negative for CD45.Their proliferative capacity and CFU-F number were similar to those of bMSCs from healthy donors. (2) MSCs significantly inhibited T,B cell proliferation. MSCs also could down-regulating the levels of IL-1, TNF and up-regulating TGF-β. (3) Flow cytometry showed that BMSCs expressed CD44, CD71and CD105, but no CD45,CD34. At 4 weeks after the cells transplantation, the implanted cells were detected in the damaged joints of the model rats, which is not founded in normal knee joints of the rats'.and at same time there are more OPG(osteoprotegerin) positive. Conclusion (1) In the aspect of morphology, immuno -phenotypen, proliferative property and colony forming unit-fibroblast (CFU-F),MSCs from bone marrow of RA patients are not different from those of MSCs isolated from bone marrow of normal donors,MSCs from the bone marrow of RA patients have the potentiality in clinical application.(2) Human bone marrow MSCs inhibited Tcell and Bcell activation and proliferation in patients with RA in vitro. And these immuno –modulatory effects were not MHC-restricted. (3) bone marrow mesenchymal stem cells prevents tissue damage in arthritis. Allogeneic MSCs can engraft at sites of tissue damage,and prepair damage. That provided positive results for developing effective therapy for Rheumatoid arthritis.
