However, the microenvironment of inflammatory outbreaks significantly restricted the factors secreted from MSCs like keratinocyte growth factor (KGF). KGF is a growth factor with tissue-repaired ability. Is there a better therapeutic prospect for MSCs in combination with compounds that promote their paracrine function? Through compound screening, we screened out isoxazole-9 (ISX-9) to promote MSCs derived KGF secretion and investigated the underlying mechanisms of action.</p><p><strong>Methods: </strong>Compounds that promote KGF secretion were screened by a dual-luciferase reporter gene assay. The TMT isotope labeling quantitative technique was used to detect the differential proteins upon ISX-9 administrated to MSCs. The expressions of NGFR, ERK, TAU, and β-catenin were detected by Western blot. In the ALI model, we measured the inflammatory changes by HE staining, SOD content detection, RT-qPCR, immunofluorescence, etc. The influence of ISX-9 on the residence time of MSCs transplantation was explored by optical in vivo imaging.</p><p><strong>Results: </strong>We found out that ISX-9 can promote the expression of KGF in MSCs. ISX-9 acted on the membrane receptor protein NGFR, upregulated phosphorylation of downstream signaling proteins ERK and TAU, downregulated phosphorylation of β-catenin, and accelerated β-catenin into the nucleus to further increase the expression of KGF. In the ALI model, combined ISX-9 with MSCs treatments upgraded the expression of KGF in the lung, and enhanced the effect of MSCs in reducing inflammation and repairing lung damage compared with MSCs alone.</p><p><strong>Conclusions: </strong>ISX-9 facilitated the secretion of KGF from MSCs both in vivo and in vitro. The combination of ISX-9 with MSCs enhanced the paracrine function and anti-inflammatory effect of MSCs compared with MSCs applied alone in ALI.

In this study, we generated HLCs from human adipose-derived mesenchymal stem cells (hADMSCs) in both 2D and 3D cultures. We performed an acetyl-proteomics assay on the HLCs derived from both 2D and 3D differentiation and identified a differential change in H3K56 acetylation between the 2 differentiated cells. Our findings revealed that 3D differentiation activated ALB gene transcription by increasing the acetylation level of H3K56, thereby enhancing the phenotypes and functions of HLCs and further promoting their maturation. Notably, inhibiting p300 reduced the acetylation level of H3K56 during hepatogenic differentiation, leading to decreased phenotypes and functions of HLCs, whereas activation of p300 promoted hepatogenic differentiation, suggesting that p300 plays a critical role in this process. In summary, our study demonstrates a potential mechanism through which 3D spheroids differentiation facilitates hADMSCs differentiation into HLCs by promoting p300-mediated H3K56 acetylation, which could have significant clinical applications in liver regeneration and disease modeling.</p>","PeriodicalId":21986,"journal":{"name":"Stem Cells Translational Medicine","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10872693/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71486281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an effort to optimize the stem cell regimen for stroke, here we conducted vis-a-vis comparison of different routes of transplantation, namely, intracerebral, intraarterial, and intranasal delivery of expanded human CD34 + stem cells, called ProtheraCytes, in the established stroke model of transient middle cerebral artery occlusion (MCAO) using adult Sprague-Dawley rats. After adjusting for the dose and subacute timing of cell delivery, animals were randomly assigned to receive either ProtheraCytes or vehicle. Motor and neurological assays from days 7 to 28 post-stroke revealed significant functional recovery across all 3 delivery routes of ProtheraCytes compared to vehicle-treated stroke rats. Additionally, ProtheraCytes-transplanted stroke rats displayed significantly reduced infarct size and cell loss in the peri-infarct area coupled with enhanced neurogenesis and angiogenesis compared to vehicle-treated stroke rats. These results highlight the safety and efficacy of transplanting ProtheraCytes, including via the minimally invasive intranasal route, in conferring robust and stable behavioral and histological positive outcomes in experimental stroke.</p>","PeriodicalId":21986,"journal":{"name":"Stem Cells Translational Medicine","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10872715/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138452569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, cell-based therapies for ALD and NAFLD have been proposed with mesenchymal stem/stromal cells (MSCs) as promising effectors. MSC therapeutic applications offer hepatoprotection, regulation of the inflammatory process and angiogenesis particularly in ALD and NAFLD pre-clinical disease models. Recent studies suggested that hepatospecific MSC-based therapies could benefit liver diseases by restoring liver function and decreasing inflammation and fibrosis. Similarly to solid-organ transplantation, limitations in MSC approaches include donor availability exacerbated by high number of cells and cell trapping into lungs.

Here, we report a VPA-based approach for cholangiocyte differentiation of human pluripotent stem cells. VPA activated Notch2 expression and upregulated HES-1, HEY-1, and Sox9 gene expression in hESC-derived hepatoblast. After 7 days treatment, VPA promoted successful differentiation of hepatoblast into cholangiocytes expressing cholangiocyte marker genes (AE2, AQP1, CFTR) and proteins (CK19 and CK7). In addition, the differentiated cholangiocytes formed bile duct-like structures after implantation into the spleen of NOD/SCID mice. Our results suggested that VPA can promote hESC differentiation to cholangiocyte-like cells.
