{"doi":"10.1016/j.ejcb.2025.151492","title":"Holotomographic microscopy reveals label-free quantitative dynamics of endothelial cells during endothelialization","abstract":"Holotomograhic microscopy (HTM) has emerged as a non-invasive imaging technique that offers high-resolution, quantitative 3D imaging of biological samples. This study explores the application of HTM in examining endothelial cells (ECs). HTM overcomes the limitations of traditional microscopy methods in capturing the real-time dynamics of ECs by leveraging the refractive index (RI) to map 3D distributions label-free. This work demonstrates the utility of HTM in visualizing key cellular processes during endothelialization, wherein ECs anchor, adhere, migrate, and proliferate. Leveraging the high resolution and quantitative power of HTM, we show that lipid droplets and mitochondria are readily visualized, enabling more comprehensive studies on their respective roles during endothelialization. The study highlights how HTM on a commercial instrument can uncover novel insights into HUVEC cell behavior, offering potential applications in medical diagnostics and research, particularly in developing treatments for cardiovascular diseases. This advanced imaging technique not only enhances our understanding of EC biology but also presents a significant step forward in the study of cardiovascular diseases, providing a robust platform for future research and therapeutic development. • Holotomographic microscopy (HTM) provides label-free, high-resolution 3D imaging of endothelial cells. • Quantitative refractive index (RI) measurements track dynamic endothelial cell behaviors without exogenous labels. • Lipid droplets and mitochondria are identified based on inherent optical properties, offering organelle-level insights. • Correlations between RI values and cellular morphology or motility reveal new quantitative markers of endothelialization. • Combining HTM with immunofluorescence provides orthogonal information of cell-cell interactions and protein localization.","journal":"European Journal of Cell Biology","year":2025,"id":525573,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9534,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":783119,"name":"Gabriela Acevedo Munares","orcid":null,"position":1,"is_corresponding":false},{"id":1142573,"name":"Christian Leycam","orcid":null,"position":2,"is_corresponding":false},{"id":1400725,"name":"Raul Michael","orcid":null,"position":3,"is_corresponding":false},{"id":1400726,"name":"Juliette Noyer","orcid":null,"position":4,"is_corresponding":false},{"id":455058,"name":"Patrick Jurney","orcid":"0000-0002-4099-2927","position":5,"is_corresponding":false},{"id":1301802,"name":"William D.
