The comet assay is a sensitive method used to predict the risk of DNA damage in individual cells, as it quantifies the tape breaks, being the alkaline version (pH &gt; 13) the most commonly used in the laboratory. Epithelial cells serve as biomatrices in genotoxicity assessments. As ca. 80% of solid cancers are of epithelial origin, the quantification of the DNA damage upon exposure of epithelial cells to a drug or drug formulation becomes relevant. Comet assays run in epithelial cells also have clinical applications in human biomonitoring, which assesses whether and to what extent is the human body exposed to environmental genotoxic compounds and how such exposure changes over time. Ocular mucosa is particularly exposed to environmental assaults. This review summarizes the published data on the genotoxicity assessment in estimating DNA damage in epithelial cells with a special focus on ocular cell lines. General comet assay procedures for ex vivo and in vivo epithelium samples are also described.<\/jats:p>","DOI":"10.3390\/ijerph17062046","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T10:01:35Z","timestamp":1584612095000},"page":"2046","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Ocular Cell Lines and Genotoxicity Assessment"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9737-6017","authenticated-orcid":false,"given":"Eliana B.","family":"Souto","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Technology, Faculty of Pharmacy, University of Coimbra, P\u00f3lo das Ci\u00eancias da Sa\u00fade, Azinhaga de Santa Comba, 3000-548 Coimbra, Portugal"},{"name":"CEB-Centre of Biological Engineering, University of Minho, Campus de Gualtar 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9245-949X","authenticated-orcid":false,"given":"Joana R.","family":"Campos","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technology, Faculty of Pharmacy, University of Coimbra, P\u00f3lo das Ci\u00eancias da Sa\u00fade, Azinhaga de Santa Comba, 3000-548 Coimbra, Portugal"}]},{"given":"Raquel","family":"Da Ana","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technology, Faculty of Pharmacy, University of Coimbra, P\u00f3lo das Ci\u00eancias da Sa\u00fade, Azinhaga de Santa Comba, 3000-548 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1564-3661","authenticated-orcid":false,"given":"Carlos","family":"Martins-Gomes","sequence":"additional","affiliation":[{"name":"Department of Biology and Environment, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, P-5001-801 Vila Real, Portugal"},{"name":"Centre for Research and Technology of Agro-Environmental and Biological Sciences, CITAB, UTAD, Quinta de Prados, P-5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7524-9914","authenticated-orcid":false,"given":"Am\u00e9lia M.","family":"Silva","sequence":"additional","affiliation":[{"name":"Department of Biology and Environment, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, P-5001-801 Vila Real, Portugal"},{"name":"Centre for Research and Technology of Agro-Environmental and Biological Sciences, CITAB, UTAD, Quinta de Prados, P-5001-801 Vila Real, Portugal"}]},{"given":"Selma B.","family":"Souto","sequence":"additional","affiliation":[{"name":"Department of Endocrinology of Hospital de S\u00e3o Jo\u00e3o, Alameda Prof. Hern\u00e2ni Monteiro, 4200\u2013319 Porto, Portugal"}]},{"given":"Massimo","family":"Lucarini","sequence":"additional","affiliation":[{"name":"CREA-Research Centre for Food and Nutrition, Via Ardeatina 546, 00178 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7747-9107","authenticated-orcid":false,"given":"Alessandra","family":"Durazzo","sequence":"additional","affiliation":[{"name":"CREA-Research Centre for Food and Nutrition, Via Ardeatina 546, 00178 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5505-3327","authenticated-orcid":false,"given":"Antonello","family":"Santini","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, University of Napoli Federico II, Via D.
