Additionally, we examined whether these immunosuppressants affect the persistence of hMSCs or the immune response upon their administration into the brain parenchyma of AD mice. The exposure of hMSCs to high concentrations of dexamethasone and tacrolimus in vitro did not significantly alter the characteristics of hMSCs. The expression of genes related to innate immune responses, such as Irak1, Irf3, Nod1, and Ifnar1, was significantly downregulated by the additional administration of dexamethasone and tacrolimus to the brain parenchyma of AD mice. However, hMSC persistence in the AD mouse brain was not affected.

Regenerative capacities vary significantly across species, with amphibians and fish demonstrating a high regenerative capacity even after severe injuries. This capacity is largely attributed to the formation of a blastema, a mass of multipotent cells reprogrammed from differentiated cells at the injury site. In contrast, mammals exhibit limited regenerative capacities, with blastema- like cells forming only in specific contexts, such as antler or digit tip regeneration. An interesting aspect of blastema formation in highly regenerative organisms is the temporary expression of pluripotency factors as known as the Yamanaka factors (YFs), which is a key requirement for reprogramming somatic cells into induced pluripotent stem cells (iPSCs). While iPSCs hold pros and cons, direct or partial reprogramming with YF has been proposed as a safer alternative. Since blastema formation and partial reprogramming are similar in terms of YF expressions, we found blastema-like cells in mammalian reprogramming with YF. This review outlines the characteristics of blastema across various organisms, emphasizing interspecies differences. We also explore studies on partial reprogramming and the possibility of inducing blastema-like cells via the temporary expression of YF in mammals.","PeriodicalId":14392,"journal":{"name":"International journal of stem cells","volume":" ","pages":"126-134"},"PeriodicalIF":2.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122245/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143585406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Promyelocytic leukemia protein (PML) was a vital regulator of cellular functions. However, the function of PML in OP remains unknown. Our research aimed to illustrate the molecular mechanism of PML in bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation. The BMSCs were identified by using flow cytometry analysis. The osteoblast differentiation ability of BMSCs was assessed through using alkaline phosphatase and Alizarin red S stainings. The relationship between hypoxia-inducible factor-1α (HIF1α) and superoxide dismutase 3 (SOD3) were confirmed by using chromatin immunoprecipitation and dual-luciferase reporter assays. The binding association between PML and hypoxia-inducible factor 1α inhibitor (HIF1AN) proteins was verified by using co-immunoprecipitation assay and immunofluorescence staining. Western blot was used for protein detection. PML was up-regulated in osteogenic differentiation of BMSCs. Functionally, PML negatively regulated HIF1AN expression by enhancing HIF1AN ubiquitination degradation. PML knockdown or HIF1AN up-regulation suppressed the osteogenic differentiation of BMSCs. Furthermore, HIF1α directly bound to the SOD3 promoter region. PML or SOD3 overexpression remarkably promoted the BMSCs osteoblast differentiation under osteogenic medium, which was reversed by LY294002. PML acts as a significant regulator in the BMSCs osteogenic differentiation by regulating the HIF1AN/HIF1α/SOD3 axis and phosphatidylinositol 3 kinase/protein kinase B pathway.","PeriodicalId":14392,"journal":{"name":"International journal of stem cells","volume":" ","pages":"146-157"},"PeriodicalIF":2.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122243/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143585466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite advancements in various treatments, the prevalence of DKD continues to rise, leading to a significant increase in the demand for dialysis and kidney transplantation. This study aimed to evaluate the effects of a Small cell＋Ultra Potent＋Scale UP cell (SMUP-Cell), a type of human umbilical cord blood-derived mesenchymal stem cell, on DKD in the db/db mouse model of type 2 diabetes mellitus. After administering SMUP-Cells via tail vein injection in db/db mice, the animals were monitored over a three-month period. The db/db mice exhibited an increased urine albumin-to-creatinine ratio (UACR). However, the administration of SMUP-Cells resulted in a reduction of the UACR. The expression levels of desmin, α-smooth muscle actin, and fibronectin-markers of epithelial-mesenchymal transition (EMT)-as well as kidney injury molecule 1, a sensitive marker of tubular injury, were significantly elevated in db/db mice. Treatment with SMUP-Cells ameliorated all of these changes. Notably, Gremlin isoform 2 (Grem2) exhibited the most significant difference in expression according to the transcriptome analysis. The elevated expression of Grem2 in db/db mice was significantly reduced following SMUP-Cell treatment. In vitro, treatment with high glucose and cholesterol induced Grem2 expression in renal tubular epithelial cells (RTECs), while Grem2 knockdown effectively prevented fibrosis and senescence induced by high glucose and cholesterol in RTECs. These observations suggest that SMUP-Cells inhibit the progression of DKD by inhibiting EMT through the reduction of Grem2 expression in RTECs.","PeriodicalId":14392,"journal":{"name":"International journal of stem cells","volume":" ","pages":"158-172"},"PeriodicalIF":2.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12122246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142930935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous reports have demonstrated that the P8 protein (P8), isolated from Lactobacillus rhamnosus, has anticancer properties. However, its efficacy in stem cells and normal cells has not been reported. In this study, the effect of P8 on cell proliferation and wound healing was evaluated, investigating its underlying mechanism. Based on scratch assay results, we demonstrated that P8 treatment significantly increases wound healing by activating the cell cycle and promoting stem cell stemness. Cellular mechanisms were further investigated by culturing stem cells in a medium containing Lactobacillus-derived P8 protein, revealing its promotion of cell proliferation and migration. Also, it is found that P8 enhances the expression of stemness markers, such as OCT4 and SOX2, along with activation of the mitogen-activated protein kinase (MAPK) signaling and Hippo pathways. These results indicate that P8 can promote cell growth by increasing stem cell proliferation, migration, and stemness in a manner associated with MAPK and Hippo signaling, which could contribute to the increased wound healing after P8 treatment. Furthermore, P8 could promote wound healing in keratinocytes by activating the MAPK signaling pathways. These results suggest that P8 might be a promising candidate to enhance stem cell culture efficiency by activating cell proliferation, and enhance therapeutic effects in skin diseases.","PeriodicalId":14392,"journal":{"name":"International journal of stem cells","volume":" ","pages":"87-98"},"PeriodicalIF":2.5,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11867908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142568396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
