Here we tested whether mutations accumulate during replicative senescence. Cellular senescence is also a possible cause of functional decline in aging, yet also acts as an anti-cancer mechanism in vivo . Using single-cell whole-genome sequencing, we compared mutation burdens between early passage and deeply senescent human fibroblasts. The results showed that single-nucleotide variations and small insertions and deletions increased in senescent cells by about two-fold, but have the same spectrum as early passage cells, while it has been known that particular mutational signatures are found in tumor cells. In contrast, aneuploidies were observed in half the senescent cells, but largely absent in early passage cells. Thus, the patterns of mutations among senescent, normal-aged and tumor cells differ significantly.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2022,"id":299487,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9423,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":989858,"name":"Marco De Cecco","orcid":null,"position":1,"is_corresponding":false},{"id":486421,"name":"Moonsook Lee","orcid":"0000-0002-5895-2114","position":2,"is_corresponding":false},{"id":374157,"name":"Xiaoxiao Hao","orcid":"0000-0003-4404-5246","position":3,"is_corresponding":false},{"id":273651,"name":"Alexander Y.
