Currently, no effective therapies exist for this ischemic complication, and the mechanisms driving left ventricular dilatation during chronic post-infarction remodeling remain poorly understood. One potential pathological process leading to ventricular dilatation involves specific compensatory rearrangements in the border zone adjacent to the infarct, which isolates the intact myocardium from inflammation at the scar edge. Using a rat model, we examined ultrastructural changes in the intact and border zones of post-infarction myocardium at chronic stages. Morphometric analysis of myofibrils, mitochondria, and excitation-contraction coupling structures revealed similar remodeling processes in both zones at 2 weeks post-infarction, characterized by decreased myofibril density, reduced mitochondrial area and volume density, and shortened contacts between T-tubules and sarcoplasmic reticulum. At 26 weeks post-infarction, during the dilated cardiomyopathy phase, we observed distinct compensatory changes in the border zone. Specifically, there was a loose arrangement of myofibrils and an increased volume fraction of mitochondria. These differences in remodeling between the intact and border zones highlight factors contributing to ventricular dilatation and help the development of new therapeutic strategies to delay heart failure progression in cardiac ischemia.</p>","PeriodicalId":11068,"journal":{"name":"Cytometry Part A","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142909423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe three novel and isotopically pure selenium-containing compounds (SeMals) that are useful cellular labeling tools. The maleimide-functionalized selenophenes (<sup>76</sup>SeMal, <sup>77</sup>SeMal, and <sup>78</sup>SeMal) covalently react with cellular sulfhydryl groups and uniquely label cell samples. The SeMal reagents label viable and paraformaldehyde-fixed peripheral blood mononuclear cells (PBMC), are well resolved by the mass cytometer, and have little spill into adjacent channels. They appear non-toxic to viable cells at working concentrations. We used SeMal reagents in combination with four isotopically pure tellurium maleimide reagents (<sup>124</sup>TeMal, <sup>126</sup>TeMal, <sup>128</sup>TeMal, and <sup>130</sup>TeMal) to label 21 individual PBMC samples with unique combinations of selenium and tellurium isotopes (seven donors with three replicates using a 7 isotope pick 2 combinatorial schema). The individually barcoded samples were pooled, stained with an antibody cocktail as a pool, and acquired on the mass cytometer as a single suspension. The single-cell data were de-barcoded into separate sample-specific files after data acquisition, enabling an uninterrupted instrument run. Each donor sample retained its unique phenotypic profile with excellent replicate reproducibility. Unlike current live cell barcoding methods, this approach does not require antibodies to surface markers, allowing for the labeling of all cells regardless of surface antigen expression. Additionally, since selenium and tellurium isotopes are not currently utilized in CyTOF antibody panels, this method expands barcoding options and frees up commonly used isotopes for more detailed cell profiling.</p>","PeriodicalId":11068,"journal":{"name":"Cytometry Part A","volume":"105 12","pages":"899-908"},"PeriodicalIF":2.5,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cyto.a.24907","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142709568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
