These pathological features are instrumental in the propagation of airway inflammation, structural remodeling, and the escalation of airway hyperresponsiveness (AHR), which are also principal factors underlying the limitations of current therapeutic strategies. In asthmatic ASM, an imbalance between oxidant production and antioxidant defenses culminates in oxidative stress, which is involved in the excessive secretion of inflammatory factors, increased mass, and amplified contractile responses of ASM, and is a critical etiological factor implicated in the dysregulation of ASM function. The molecular pathways through which oxidative stress exerts its effects on ASM in asthma are multifaceted, with the Nrf2/HO-1, MAPK, and PI3K/Akt pathways being particularly noteworthy. These characteristic pathways play a potential role by connecting with different upstream and downstream signaling molecules and are involved in the amplification of ASM inflammatory responses, increased mass, and AHR. This review provides a comprehensive synthesis of the phenotypic expression of ASM dysfunction in asthma, the interplay between oxidants and antioxidants, and the evidence base and molecular underpinnings linking oxidative stress to ASM dysfunction. Given the profound implications of ASM dysfunction on the airflow limitation in asthma and the seminal role of oxidative stress in this process, a deeper exploration of these mechanisms is essential for unraveling the pathogenesis of asthma and may offer novel perspectives for its prophylaxis and management.","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"17-34"},"PeriodicalIF":3.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In common with other related species such as the American cockroach, Periplaneta americana, female-emitted sex pheromone components, named periplanones, are known to be key volatiles that elicit long-range attraction and courtship rituals in males. How periplanones are processed in the nervous system has been entirely unexplored in P. fuliginosa. By using pheromone compounds, periplanones A, B, C, and D, as stimulants to the antenna, we identified four distinct types of interneurons (projection neurons) that relay pheromonal signals from a single olfactory glomerulus of the first-order olfactory center (antennal lobe) to higher-order centers in the ipsilateral hemibrain. All glomeruli innervated by pheromone-responsive projection neurons clustered near the antennal nerve entrance of the antennal lobe. The projection neuron with dendrites in the largest glomerulus was tuned specifically to periplanone-D, and adding other components to periplanone-D counteracted the excitation elicited by periplanone-D alone. Likewise, the projection neuron with dendrites in the second largest glomerulus and that with dendrites in a medium-sized glomerulus were tuned to periplanone-A and periplanone-B, respectively. Our results are, therefore, consistent with behavioral findings that periplanone-D alone acts as a primary sex attractant and that other components act as potential behavioral antagonists. Moreover, a comparison of the glomeruli in P. fuliginosa and P. americana suggested that there are differences in the sizes of homologous glomeruli, as well as in the ligands they process.","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"51-70"},"PeriodicalIF":3.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142945223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we aimed to clarify the developmental process of the mucosal nerve network and submucosal neurons (SM-neurons) or ganglia (SMG), which are the main source of nerve fibers projected to the mucosa, in the rat ileum during the postnatal period. Immunohistochemistry against tubulin beta III (Tuj1) revealed that Tuj1-immunopositivities were more abundant in the lamina propria at 2 weeks old (2wk; pre-weaning) than at postnatal day 0 (P0) or 4 weeks old (4wk; post-weaning) and more frequent on the mesenteric side than on the antimesenteric side at 2wk. Hu antigen D (HuD)-immunopositive SM-neurons and SMG were also more abundantly localized on the mesenteric side than the antimesenteric side at P0 and 2wk. On the other hand, cells immunopositive for SRY-related HMG-box 10 (Sox10), which is the marker for enteric nervous system progenitor cells and enteric glial cells, were homogenously scattered in the submucosa throughout the entire circumference at all ages. Glial cell marker S100 calcium-binding protein B (S100β) in the submucosa was detected at all ages without any significant difference between the mesenteric and antimesenteric sides. These findings indicate that SMG formation and associated neurite extension into the mucosa in the rat ileum might occur preferentially on the mesenteric side by the weaning period, leading us to hypothesize that the mechanism by which the mucosal nerve network and SMG develop differs along the mesenteric-antimesenteric side axis.","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"71-80"},"PeriodicalIF":3.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11965212/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143406102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The planarian Dugesia japonica contains a reservoir of stem cells that grow and divide continuously to support cellular turnover. However, whether SOX proteins retain these conserved functions in planarians remains to be determined. In this study, three sox gene homologs, DjsoxP-1, DjsoxP-5, and Djsox5, were identified in the planarian transcriptome, and their roles were investigated. The results showed that the amino acids deduced from the three sox genes all contained high-mobility group (HMG) domain sequences, which are highly conserved in sox family members. Whole-mount in situ hybridization (WISH) and real-time quantitative PCR (RT-qPCR) results indicated that the three sox genes were mainly expressed in parenchymal tissues and regenerative blastema. Additionally, X-ray irradiation assay and dFISH suggested that the three Djsox genes were expressed in neoblasts and other cell types. Head regression in intact planarian and smaller blastemas in both head or tail fragments of regenerating planarians were exhibited with DjsoxP-1 and Djsox5 RNA interference (RNAi) compared to the control animals, suggesting that DjsoxP-1 and Djsox5 have essential roles during cellular turnover and regeneration in planarians; conversely, there was no obvious phenotypic abnormalities or regeneration defect in DjsoxP-5 RNAi animals. Knockdown of DjsoxP-1 or Djsox5 decreased neoblast proliferation and promoted cell apoptosis. In conclusion, our findings demonstrate that DjsoxP-1 and Djsox5 are involved in cellular turnover and regeneration in planarians by modulating coordination between cell proliferation and apoptosis.","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":"399 3","pages":"337-350"},"PeriodicalIF":3.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies reported that some SOX2-positive cells of the anterior lobe differentiate into skeletal muscle cells. These findings suggest that CD9/SOX2-positive cells in the anterior pituitary have mesenchymal stem cell (MSC) properties. To substantiate this hypothesis, we examined whether CD9-positive cells isolated from IL-MCL of adult male rats differentiate into mesenchymal cells, such as endothelial cells, adipocytes, chondrocytes, and osteocytes. Immunohistochemical analysis revealed that the CD9-positive cells were positive for the MSC markers, CD349, CD105, CD271, and CD273 and were detected in the early postnatal period at the boundary between the posterior and intermediate lobes but not in the embryonic period. In addition, some adult tissue stem cells derived from neural crest cells and bone marrow haematopoietic stem cells were positive for both CD9 and MSC markers, indicating that several CD9/SOX2-positive cells in the IL-MCL of the pituitary gland are MSCs that invaded from external tissues during pituitary development in the early postnatal period and exist in the adult tissue stem cells as suppliers of hormone-producing and endothelial cells in the anterior lobe.

Replenishment of malfunctioning β-cells via islet transplantation has the potential to induce long-term glycemic control in the body. However, this treatment option cannot widely be implemented in clinical due to healthy islet donor shortage. Emerging β-cell replacement with human-induced pluripotent stem cell (iPSC) provides high remedial therapy hopes. Thus, tremendous progress has been made in developing β-cell differentiation protocols in vitro; however, most of the differentiated iPSC-derived β-cells showed immature phenotypes associated with low efficiency depending on the iPSC lines used, creating a crucial barrier for their clinical implementation. Multiple mechanisms including differences in genetic, cell cycle patterns, and mitochondrial dysfunction underlie the defective differentiation propensity of iPSC into insulin-producing β-cells. Accumulating evidence recently indicated that, following the reprogramming, epigenetic memory inherited from parental cells substantially affects the differentiation capacity of many iPSC lines. Therefore, differences in epigenetic signature are likely to be essential contributing factors influencing the propensity of iPSC differentiation. In this review, we will document the impact of the epigenome on the reprogramming efficacy and differentiation potential of iPSCs and how targeting the epigenetic residual memory could be an additional strategy to improve the differentiation efficiency of existing protocols to generate fully functional hPSC-derived pancreatic β-cells for diabetes therapy and drug screening.","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"267-276"},"PeriodicalIF":3.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11870940/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the potential of the recently developed Xenium platform for high-resolution spatial transcriptomic analysis of human skeletal muscle histological sections. Human vastus lateralis muscle samples from two individuals were analysed using the Xenium platform and Human Multi-Tissue and Cancer Panel targeting 377 genes complemented by staining of successive sections for Myosin Heavy Chain isoforms to differentiate between type 1 and type 2 muscle fibres. Manual segmentation of muscle fibres allowed accurate comparisons of transcript densities across fibre types and subcellular regions, overcoming limitations in the platform's automated segmentation. The analysis revealed higher transcript density in type 1 fibres, particularly in nuclear and perinuclear areas, and identified 191 out of 377 genes with differential expression between muscle fibres and perimysium. Genes such as PROX1, S100A1, LGR5, ACTA2, and LPL exhibited higher expression in type 1 fibres, whereas PEBP4, CAVIN1, GATM, and PVALB in type 2 fibres. We demonstrated that the Xenium platform is capable of high-resolution spatial in situ transcriptomic analysis of skeletal muscle histological sections.
