Thus, establishing alternative laboratory models is crucial for investigating the diverse physiological adaptations observed in bats. Obtaining quality cells from tissues is a critical first step for successful primary cell derivation. However, it is often impractical to collect fresh tissue and process the samples immediately for cell culture due to the resources required for isolating and expanding cells. As a result, frozen tissue is typically the starting resource for bat primary cell derivation. Yet, cells in frozen tissue are usually damaged and represent low integrity and viability. As a result, isolating primary cells from frozen tissues poses a significant challenge. Herein, we present a successfully developed protocol for isolating primary dermal fibroblasts from frozen bat wing biopsies. This protocol marks a significant milestone, as this the first protocol specially focused on fibroblasts isolation from bat frozen tissue. We also describe methods for primary cell characterization, genetic manipulation of primary cells through lentivirus transduction, and the development of stable cell lines.\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Basic Protocol 1:</jats:bold>\n                  Bat wing biopsy collection and preservation\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 1:</jats:bold>\n                  Blood collection from bat-venipuncture\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Basic Protocol 2:</jats:bold>\n                  Isolation of primary fibroblasts from adult bat frozen wing biopsy\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 2:</jats:bold>\n                  Maintenance of primary fibroblasts\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 3:</jats:bold>\n                  Cell banking and thawing of primary fibroblasts\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 4:</jats:bold>\n                  Growth curve and doubling time\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 5:</jats:bold>\n                  Lentiviral transduction of bat primary fibroblasts\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Basic Protocol 3:</jats:bold>\n                  Bat stable fibroblasts cell lines development\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 6:</jats:bold>\n                  Bat fibroblasts validation by immunofluorescence staining\n                </jats:p>\n                <jats:p>\n                  <jats:bold>Support Protocol 7:</jats:bold>\n                  Chromosome counting\n                </jats:p>","journal":null,"year":null,"id":649168,"datarank":0.16479184330021646,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"self_citation_contribution":0.16479184330021646,"citation_network_contribution":0.0,"self_endowment_contribution":0.16479184330021646,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1692224,"name":"Pedro Morales-Sosa","orcid":null,"position":1,"is_corresponding":false},{"id":1437024,"name":"Andrea Bernal‐Rivera","orcid":"0000-0003-4262-9977","position":2,"is_corresponding":false},{"id":1341077,"name":"Yan Wang","orcid":"0000-0002-7731-8100","position":3,"is_corresponding":false},{"id":560927,"name":"Dai Tsuchiya","orcid":"0000-0001-8385-2775","position":4,"is_corresponding":false},{"id":1692226,"name":"Jose Emmanuel Javier","orcid":null,"position":5,"is_corresponding":false},{"id":560930,"name":"Nicolas Rohner","orcid":"0000-0003-3248-2772","position":6,"is_corresponding":false},{"id":647682,"name":"Chongbei Zhao","orcid":"0000-0002-7224-5600","position":7,"is_corresponding":false},{"id":506025,"name":"Jasmin Camacho","orcid":"0000-0001-6449-9224","position":8,"is_corresponding":false},{"id":16253,"name":"Fengyan Deng","orcid":"0000-0003-0097-2777","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"resolved":true,"title":"Establishing Primary and Stable Cell Lines from Frozen Wing Biopsies for Cellular, Physiological, and Genetic Studies in Bats","abstract":"<jats:title>Abstract</jats:title>\n                <jats:p>\n                  Bats stand out among mammalian species for their exceptional traits, including the capacity to navigate through flight and echolocation, conserve energy through torpor/hibernation, harbor a multitude of viruses, exhibit resistance to disease, survive harsh environmental conditions, and demonstrate exceptional longevity compared to other mammals of similar size.\n                  <jats:italic>In vivo</jats:italic>\n                  studies of bats can be challenging for several reasons such as ability to locate and capture them in their natural environments, limited accessibility, low sample size, environmental variation, long lifespans, slow reproductive rates, zoonotic disease risks, species protection, and ethical concerns.
