In vivo, animal experiments confirmed that BMSCs-XIST significantly alleviated SCI by promoting NSC differentiation and axon formation in the injured area.

The most effective treatment available for these patients is whole organ transplantation; however, due to the severely limited supply of donor livers and the side effects associated with the immunosuppressive regimen required to accept allograft, the mortality rate in patients with end-stage liver disease is annually rising. Stem cell-based therapy aims to provide alternative treatments by either cell transplantation or bioengineered construct transplantation. Human amnion epithelial cells (AEC) are a widely available, ethically neutral source of cells with the plasticity and potential of multipotent stem cells and immunomodulatory properties of perinatal cells.

Decellularised extracellular matrix (ECM) scaffolds have gained recognition as adjunct biological support. Decellularised scaffolds maintain native ECM components and the 3D architecture instrumental of the organ, necessary to support cells' maturation and function. We combined ECM-scaffold technology with primary human AEC, which we demonstrated being equipped with essential ECM-adhesion proteins, and evaluated the effects on AEC differentiation into functional hepatocyte-like cells (HLC). This novel approach included the use of a custom 4D bioreactor to provide constant oxygenation and media perfusion to cells in 3D cultures over time. We successfully generated HLC positive for hepatic markers such as ALB, CYP3A4 and CK18. AEC-derived HLC displayed early signs of hepatocyte phenotype, secreted albumin and urea, and expressed Phase-1 and -2 enzymes.

Such techniques harness the ability of different cell types to promote angiogenesis, re-epithelialization of the skin, and tissue regeneration. This systematic review explores the efficacy of cell-based therapies and tissue engineering in treating deep PI. We searched for interventional studies using cells in the treatment of PI in adults in four online libraries (PubMed, Embase, Ovid Medline, and Cochrane; latest search 10th June 2023). We found one randomized clinical trial (RCT), two non-RCT, and three pre-post studies, comprising 481 study participants with PI (253 intervention/228 controls). The risk of bias was categorized as moderate due to minimal bias in outcome measurements, or high owing to unclear patient randomization methods, as assessed by the ROBINS-I, NIH, and RoB-2 tools. Four cell types were identified in the context of cell-based therapies of PI: bone marrow mononuclear stem cells (BM-MNCs, <i>n</i> = 2); hematopoietic derived stem cells (HSC, <i>n</i> = 1); macrophages and activated macrophage suspensions (AMS, <i>n</i> = 2); and cryopreserved placental membrane containing viable cells (vCPM, <i>n</i> = 1). Wound healing outcomes were observed in patients undergoing cell-based therapies, including complete wound closure (AMS, vCPM; <i>n</i> = 142), faster healing rate (BM-MNCs, AMS; <i>n</i> = 146), improved granulation tissue formation (HSC, <i>n</i> = 3) and shorter hospitalization time (BM-MNCs; <i>n</i> = 108) compared to standard of care, with no adverse reactions. PI healing rate decreased only in one study with BM-MNC therapy, compared to control (<i>n</i> = 86). Based on the available data, though with limited evidence, it seems that macrophage deployment showed the most favorable outcomes.

It is a multi-etiological and fulminant complication with a clinical mortality of over 80%. Therapy using mesenchymal stem cells (MSCs) or MSCs-derived exosomes can alleviate acute liver injury, which has been demonstrated in animal experiments and clinical application. However, similar to other stem cells, different cell sources, poor stability, cell senescence and other factors limit the clinical application of MSCs. To achieve mass production and quality control on stem cells and their exosomes, transfecting umbilical cord mesenchymal stem cell (UCMSC) with lentivirus overexpressing human telomerase reverse transcriptase (hTERT) gene, the hTERT-UCMSC was constructed as an immortalized MSC cell line. Compared with the primary UCMSC (P3) and immortalized cell line hTERT-UCMSC at early passage (P10), the hTERT-UCMSC retained the key morphological and physiological characteristics of UCMSC at the 35th passage (P35), and showed no signs of carcinogenicity and toxic effect in mice. There was no difference in either exosome production or characteristics of exosomes among cultures from P3 primary cells, P10 and P35 immortalized hTERT-UCMSCs. Inoculation of either hTERT-UCMSC (P35) or its exosomes improved the survival rate and liver function of ALF mice induced by thioacetamide (TAA). Our findings suggest that this immortalized cell line can maintain its characteristics in long-term culture. Inoculation of hTERT-UCMSC and its exosomes could potentially be used in clinics for the treatment of liver failure in the future.</p>","PeriodicalId":17384,"journal":{"name":"Journal of Tissue Engineering","volume":"14 ","pages":"20417314231200328"},"PeriodicalIF":8.2,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/6b/91/10.1177_20417314231200328.PMC10510347.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41134197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
