[PMID: 38373743 PMCID: PMC10988675 DOI: 10.1002/2211-5463.13781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 01/04/2024] [Accepted: 02/09/2024] [Indexed: 02/21/2024] Open
Abstract
The Egyptian Rousettus bat (Rousettus aegyptiacus) is a common fruit bat species that is distributed mainly in Africa and the Middle East. Bats serve as reservoir hosts for numerous pathogens. Human activities, such as hunting bats for food, managing vermin, and causing habitat loss, elevate the likelihood of transmission of bat pathogens to humans and other animals. Consequently, bat cell lines play a crucial role as research materials for investigating viral pathogens. However, the inherent limitation of finite cell division in primary cells necessitates the use of immortalized cells derived from various bat tissues. Herein, we successfully established six fibroblast cell lines derived from an infant bat heart and lungs and an elderly bat heart. Three of the six cell lines, called K4DT cells, were transduced by a combination of cell cycle regulators, mutant cyclin-dependent kinase 4, cyclin D1, and human telomerase reverse transcriptase. The other three cell lines, named SV40 cells, were transfected with simian virus 40 large T antigen. Transgene protein expression was detected in the transduced cells. All three K4DT cell lines and one lung-derived SV40 cell line were virtually immortalized and nearly maintained the normal diploid karyotypes. However, the two other heart-derived SV40 cell lines had aberrant karyotypes and the young bat-derived cell line stopped proliferating at approximately 40 population doublings. These bat cell lines are valuable for studying pathogen genomics and biology.

Establishment and Characterization of a Primary Fibroblast Cell Culture from the Amazonian Manatee ( Trichechus inunguis). Animals (Basel) 2024; 14:686.

Abstract
The vulnerable status of the Amazon manatee, Trichechus inunguis, indicates the need to seek measures to guarantee its conservation. In this context, the cultivation of cells in vitro is a strategy that should at least guarantee the preservation of their genetic material. Thus, we established for the first time a primary culture of Amazonian manatee fibroblasts (TINsf) from a skin biopsy of a young male. Karyotypic analysis of the 3rd, 7th, and 12th passages confirmed the taxonomic identity of the species T. inunguis (2n = 56/NF = 92) and indicated that this culture presents genomic stability. Gene and protein expression of vimentin at the 13th passage show the predominant presence of fibroblasts in TINsf. To test the cell line's responsiveness to materials and demonstrate a possible application of this culture, it was exposed to andiroba seed oil (ASO), and its viability and proliferative capacity were evaluated. ASO demonstrated toxic effects at the highest concentrations and longest exposure times tested, reproducing results observed in human cultures, indicating the applicability of TINsf in toxicological and biotechnological studies. After cryopreservation, the TINsf line maintained its proliferative potential, indicating the establishment of a new culture available for future studies.

Abstract
Immortalized cells serve as a crucial research tool that capitalizes on their robust proliferative properties for functional investigations of an organism. Establishing an immortalized American miniature horse cell line could yield valuable insights into these animals' genetic and physiological characteristics and susceptibility to health issues. To date, immortalized small horse cells with normal karyotypes have not been established. In this study, we successfully established primary and immortalized fibroblast cell lines through the combined expression of human-derived mutant cyclin-dependent kinase 4 (CDK4R24C), cyclin D1, and Telomerase Reverse Transcriptase (TERT), although CDK4R24C and cyclin D1, SV40T and TERT did not result in successful immortalization. Our comparison of the properties of these immortalized cells demonstrated that K4DT immortalized cells maintain a normal karyotype. Ultimately, our findings could pave the way for the development of targeted interventions to enhance the health and well-being of American miniature horses.

Abstract
Fibroblast is one component of connective tissue cells in polygonal or stellate with cytoplasmic processes or projections. In vitro, tissue culture is an excellent medium used in biomedical research. The goal of this study was to analyze Toxicity and Malignancy in Embryo of Super Java Chicken as Potential Candidates of Strong Poultry in Indonesia. This study used Preparation of fibroblast primary cell culture of Java super chicken embryos, Pathogenicity test using fibroblast cells from Super Java chicken, Toxicity test using fibroblast cells from Super Java Chicken. Primary fibroblast cell culture of Java super chicken embryos was prepared from 10-day-old brood chicken eggs free of pathogens. Cells were prepared in 96-well microplates with minimal essential medium (MEM) containing 10 % fetal calf serum (FCS) 100 IU/ug penicillin/streptomycinVirus isolates were diluted in stages from 10-2 to 10-5 and inoculated into Java Super Chicken Fibroblast cell culture. The result showed that the negative control of the samples had a faster proliferative power than the fibroblast cell culture of Java super chicken, which was treated with concentrations of 10-2; 10-3; 10-4; 10-5. Moreover, before being inoculated with the virus, the confluent fibroblast cells of Java super chicken looked oval and regular. The day after infection, syncytia (large multinucleated cells) began to form on a small scale and became more pronounced on the second and third post-infection days. CPE was found in the 10-2,10-3 and 10-4 virus dilutions, and CPE was not found in the 10-5 dilution.

PLoS One 2023; 18:e0290436. [PMID: 37607189 PMCID: PMC10443837 DOI: 10.1371/journal.pone.0290436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 08/08/2023] [Indexed: 08/24/2023] Open
Abstract
The Okinawa rail is endemic to Okinawa Island and is categorized as an endangered animal. In this study, we focused on innate immunity because it is the first line of host defense. In particular, signals recognizing foreign RNA (e.g., viruses) are important for host defense because they activate the host immune system. The retinoic acid-inducible gene I (RIG-I)-like receptor (RLR) families (RIG-I, MDA5, and LGP2) are sensors that activate innate immunity. Therefore, we analyzed these functions in the Okinawa rail using genomic and cellular analyses of fibroblasts. Fibroblasts can be obtained from dead individuals, allowing these cells to be obtained from dead individuals, which is particularly useful for endangered species. The MDA5 gene of Okinawa rail was sequenced using the Sanger method following PCR amplification and extraction of the amplified sequence from agarose gel. Additionally, mRNA expression analysis of cultured fibroblasts exposed to poly I:C was done. The MDA5 gene was found to be a mutated nonfunctional gene in the Okinawa rail. The mRNA expression rates of inflammatory cytokine genes type I IFN, and Mx1 were slower in Okinawa rail than in chicken cultured fibroblasts. Similar to the mRNA expression results, cell number and live cell ratio also slowly decreased in the Okinawa rail compared with chicken cultured fibroblasts, indicating that the innate immune reaction differs between chicken and the Okinawa rail. To the best of our knowledge, this is the first experimental evaluation of the loss of function of the Okinawa rail innate immune genes. In conclusion, our results provide a basis for conservation strategies for the endangered Okinawa rail.

Abstract
Sheep are important domestic animals for the production of wool and meat. Although numerous cultured cell lines from humans and mice have been established, the number of cell lines derived from sheep is limited. To overcome this issue, the efficient establishment of a sheep-derived cell line and its biological characterization is reported. Mutant cyclin-dependent kinase 4, cyclin D1, and telomerase reverse transcriptase were introduced into sheep muscle-derived cells in an attempt to immortalize primary cells using the K4DT method. Furthermore, the SV40 large T oncogene was introduced into the cells. The successful immortalization of sheep muscle-derived fibroblasts was shown using the K4DT method or SV40 large T antigen. Furthermore, the expression profile of established cells showed close biological characteristics of ear-derived fibroblasts. This study provides a useful cellular resource for veterinary medicine and cell biology.

PLANT METHODS 2023; 19:41. [PMID: 37120601 PMCID: PMC10148486 DOI: 10.1186/s13007-023-01009-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 03/20/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND PacBio HiFi sequencing provides highly accurate long-read sequencing datasets which are of great advantage for whole genome sequencing projects. One limitation of the method is the requirement for high quality, high molecular weight input DNA. This can be particularly challenging for plants that frequently contain common and species-specific secondary metabolites, which often interfere with downstream processes. Cape Primroses (genus Streptocarpus), are some of these recalcitrant plants and are selected here as material to develop a high quality, high molecular weight DNA extraction protocol for long read genome sequencing. RESULTS We developed a DNA extraction method for PacBio HiFi sequencing for Streptocarpus grandis and Streptocarpus kentaniensis. A CTAB lysis buffer was employed to avoid guanidine, and the traditional chloroform and phenol purification steps were replaced with pre-lysis sample washes. Best cells/nucleus lysis was achieved with 4 h at 58 °C. The obtained high quality and high molecular weight DNAs were tested in PacBio SMRTBell™ library preparations, which resulted in circular consensus sequencing (CCS) reads from 17 to 27 Gb per cell, and a read length N50 from 14 to 17 kbp. To evaluate the quality of the reads for whole genome sequencing, they were assembled with HiFiasm into draft genomes, with N50 = 49 Mb and 23 Mb, and L50 = 10 and 11. The longest contigs were 95 Mb and 57 Mb respectively, showing good contiguity as these are longer than the theoretical chromosome length (genome size/chromosome number) of 78 Mb and 55 Mb, for S. grandis and S. kentaniensis respectively. CONCLUSIONS DNA extraction is a critical step towards obtaining a complete genome assembly. Our DNA extraction method here provided the required high quality, high molecular weight DNA for successful standard-input PacBio HiFi library preparation. The contigs from those reads showed a high contiguity, providing a good starting draft assembly towards obtaining a complete genome. The results obtained here were highly promising, and demonstrated that the DNA extraction method developed here is compatible with PacBio HiFi sequencing and suitable for de novo whole genome sequencing projects of plants.

Abstract
The Ryukyu long-furred rat is an endangered species confined to the southernmost three small islands of Japan (Amami-Oshima, Tokunoshima, and Okinawa). Its population is rapidly decreasing because of roadkill, deforestation, and feral animals. To date, its genomic and biological information are poorly understood. In this study, we successfully immortalized Ryukyu long-furred rat cells by expressing a combination of cell cycle regulators, mutant cyclin-dependent kinase 4 (CDK4R24C) and cyclin D1, together with telomerase reverse transcriptase or an oncogenic protein, the Simian Virus large T antigen. The cell cycle distribution, telomerase enzymatic activity, and karyotype of these two immortalized cell lines were analyzed. The karyotype of the former cell line immortalized with cell cycle regulators and telomerase reverse transcriptase retained the nature of the primary cells, while that of the latter cell line immortalized with the Simian Virus large T antigen had many aberrant chromosomes. These immortalized cells would be valuable for studying the genomics and biology of Ryukyu long-furred rats.

Generation and characterization of genome-modified chondrocyte-like cells from the zebra finch cell line immortalized by c-MYC expression. Front Zool 2022; 19:18.

Abstract
BACKGROUND Due to their cost effectiveness, ease of use, and unlimited supply, immortalized cell lines are used in place of primary cells for a wide range of research purposes, including gene function studies, CRISPR-based gene editing, drug metabolism tests, and vaccine or therapeutic protein production. Although immortalized cell lines have been established for a range of animal species, there is still a need to develop such cell lines for wild species. The zebra finch, which is used widely as a model species to study the neurobiological basis of human speech disorders, has been employed in several functional studies involving gene knockdown or the introduction of exogenous transgenes in vivo; however, the lack of an immortalized zebra finch cell line has hampered precise genome editing studies. RESULTS Here, we established an immortalized cell line by a single genetic event, expression of the c-MYC oncogene, in zebra finch embryonic fibroblasts and examined its potential suitability for gene targeting investigations. Retroviral vector-mediated transduction of c-MYC was used to immortalize zebra finch primary fibroblasts; the transformed cells proliferated stably over several passages, resulting in the expression of chondrocyte-specific genes. The transfection efficiency of the immortalized cells was much higher than that of the primary cells. Targeted knockout of the SOX9 gene, which plays a role in the differentiation of mesenchymal progenitor cells into chondrocytes, was conducted in vitro and both apoptosis and decreased expression levels of chondrogenic marker genes were observed in edited cells. CONCLUSIONS The c-MYC induced immortalized chondrocyte-like cell line described here broadens the available options for establishing zebra finch cell lines, paves the way for in-depth biological researches, and provides convenient approaches for biotechnology studies, particularly genomic modification research.

Abstract
Immortalized kidney cell lines are widely used in basic and applied research such as cell permeability tests and drug screening. Although many cell lines have been established from kidney tissues, the immortalization process has not been clarified in these cell lines. In this study, we analyzed the phenotypic changes that occurred during the immortalization of kidney cells derived from Chinese hamster tissue in terms of karyotype and gene expression profiles. In the newly established cell line, designated as CHK-Q, gene expression profiles at each stage of the immortalization process and during the adaptation to serum-free conditions were analyzed by DNA microarray. Renal stem cell markers CD24 and CD133 were expressed in CHK-Q cells, suggesting that CHK-Q cells were transformed from renal stem cells. Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis to identify the pathways of upregulated and downregulated genes revealed that the immortalization of CHK-Q cells was associated with increased fluctuations in the expression of specific proto-oncogenes. Karyotype analysis of spontaneously immortalized CHK-Q cells indicated that CHK-Q chromosomes had a typical modal number of 23 but possessed slight chromosomal abnormalities. In this study, we investigated the mechanism of cell environmental adaptation by analyzing gene expression behavior during the immortalization process and serum-free adaptation. CHK-Q cells are applicable to the fields of biotechnology and biomedical science by utilizing their characteristics as kidney-derived cells.

Abstract
The zebra finch is one of the most commonly studied songbirds in biology, particularly in genomics, neuroscience and vocal communication. However, this species lacks a robust cell line for molecular biology research and reagent optimization. We generated a cell line, designated CFS414, from zebra finch embryonic fibroblasts using the SV40 large and small T antigens. This cell line demonstrates an improvement over previous songbird cell lines through continuous and density-independent growth, allowing for indefinite culture and monoclonal line derivation. Cytogenetic, genomic, and transcriptomic profiling established the provenance of this cell line and identified the expression of genes relevant to ongoing songbird research. Using this cell line, we disrupted endogenous gene sequences using S.aureus Cas9 and confirmed a stress-dependent localization response of a song system specialized gene, SAP30L. The utility of CFS414 cells enhances the comprehensive molecular potential of the zebra finch and validates cell immortalization strategies in a songbird species.

Detailed chromosome analysis of wild-type, immortalized fibroblasts with SV40T, E6E7, combinational introduction of cyclin dependent kinase 4, cyclin D1, telomerase reverse transcriptase. In Vitro Cell Dev Biol Anim 2021; 57:998-1005. [PMID: 34888747 DOI: 10.1007/s11626-021-00631-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Accepted: 10/22/2021] [Indexed: 10/19/2022]
Abstract
Cell immortalization enables us to expand the cultured cell infinitely. However, the process of immortalization sometimes changes the nature of the original cell. In this study, we established immortalized embryonic fibroblasts with oncogenic SV40T and human papilla virus-derived E6E7, combinational expression of mutant cyclin-dependent kinase 4 (CDK4), cyclin D1, and telomerase reverse transcriptase (TERT) from identical primary wild-type human embryonic fibroblasts (HE16). After the establishment of immortalized cells, we compared the details of chromosome condition with the G-banding and Q-banding methods. There is no example of detailed analysis so far about chromosome abnormalities, such as trisomy, ring chromosome, reciprocal translocation, and dicentric chromosomes. The detailed chromosome analysis revealed that immortalized cells with SV40T and E6E7 showed intensive chromosome abnormalities, such as gain or loss of the chromosomes all through the genome. Furthermore, we detected that the incidence of chromosome abnormities in the immortalized cell with the combinational introduction of R24C mutant of CDK4, cyclin D1, and TERT is almost identical to that of wild-type cell. Furthermore, short tandem repeat analysis demonstrated that the origin of K4DT cell is primary HE16. These results showed that cellular immortalization with CDK4, cyclin D1, and TERT is more advantageous in keeping the chromosome's original condition than oncogenic immortalization methods.

KAv-1 is Better Suited to Chick Fibroblast Culture than DMEM or 199 Media. J Poult Sci 2021; 58:270-279. [PMID: 34899023 PMCID: PMC8630408 DOI: 10.2141/jpsa.0200085] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 02/01/2021] [Indexed: 12/27/2022] Open
Abstract
Cultured cells are a useful resource for poultry scientists, since these cells allow scientists to evaluate biological responses to conditions such as infectious diseases in vitro while mimicking the whole-body response in birds. However avian cell culture requires an optimized basal medium, and there are currently relatively few options for this basal medium (medium 199 and KAv-1). This means that there is still room for the development of an optimal basal medium for avian cell culture. Here we compare KAv-1 medium, Dulbecco's modified Eagle medium (DMEM) and medium 199 during the culture of chick fibroblasts and determine that KAv-1 remains the optimal medium for these assays. Our results show that DNA damage is reduced in fibroblasts cultured in the KAv-1 medium, when compared to both DMEM and Medium 199 and that these cells also display improved growth dynamics in KAv-1 medium when compared to both DMEM and medium 199. To the best of our knowledge, this is the first study to describe a comparative analysis of culture media for avian cells, which would provide useful information for poultry scientists.

Abstract
The Bonin flying fox (Pteropus pselaphon) is one of the most critically endangered species of animals. The number of this species is estimated to be around 150; being classified at the top rank in the list by International Union of Animal Conservation. Our group previously showed that expression of CDK4, CYCLIN D1, and telomerase reverse transcriptase (TERT) efficiently induce immortalization of human, bovine, swine, monkey, and buffalo-derived cells. In this manuscript, we successfully established the primary cells from Bonin flying fox. We introduced CDK4, CYCLIN D1, and TERT into the primary cells. The established cells showed efficient expression of introduced genes at the protein level. Furthermore, the established cells were free from senescence, indicating it reached to immortalization. Moreover, we showed that interspecies somatic cell nuclear transfer of Bonin flying fox derived cell into bovine embryo allowed the development of the embryo to 8 cell stages. Our established cell has the potential to contribute to species conservation.
