Controlled cell proliferation and immortalization of human dental pulp stem cells with a doxycycline-inducible expression system. Cell Biochem Funct 2024; 42:e4064. [PMID: 38807466 DOI: 10.1002/cbf.4064] [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: 02/20/2024] [Revised: 05/12/2024] [Accepted: 05/18/2024] [Indexed: 05/30/2024]
Abstract
Human dental pulp stem cells are a potentially useful resource for cell-based therapies and tissue repair in dental and medical applications. However, the primary culture of isolated dental pulp stem cells has notably been limited. A major requirement of an ideal human dental pulp stem cell culture system is the preservation of efficient proliferation and innate stemness over prolonged passaging, while also ensuring ease of handling through standard, user-friendly culture methods. In this study, we have engineered a novel human dental pulp stem cell line, distinguished by the constitutive expression of telomerase reverse transcriptase (TERT), and the conditional expression of the R24C mutant cyclin-dependent kinase 4 (CDK4R24C) and Cyclin D1. We have named this cell line Tet-off K4DT hDPSCs. Furthermore, we have conducted a comprehensive comparative analysis of their biological attributes in relation to a previously immortalized human dental pulp stem cells, hDPSC-K4DT, which were immortalized by the constitutive expression of CDK4R24C, Cyclin D1 and TERT. In Tet-off K4DT cells, the expression of the K4D genes can be precisely suppressed by the inclusion of doxycycline. Remarkably, Tet-off K4DT cells demonstrated an extended cellular lifespan, increased proliferative capacity, and enhanced osteogenic differentiation potential when compared to K4DT cells. Moreover, Tet-off K4DT cells had no observable genomic aberrations and also displayed a sustained expression of stem cell markers even at relatively advanced passages. Taken together, the establishment of this new cell line holds immense promise as powerful experimental tool for both fundamental and applied research involving dental pulp stem cells.

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.

Abstract
Primary cultured cells cannot proliferate infinite. The overcoming of this limit can be classified as immortalization. Bypass of p16 senescence protein induces efficient immortalization various types of mammalians is previously reported. However, the Cetacea species is not known. Here, that common minke whale-derived cells can be immortalized with a combination of human genes, mutant cyclin-dependent kinase 4 (CDK4R24C ), cyclin D1, and Telomerase Reverse Transcriptase (TERT) is reported. These results indicate that the function of cell cycle regulators in premature senescence is evolutionarily conserved. This study describes the conserved roles of cell cycle regulators in the immortalization of cells from humans to Cetacea species. Furthermore, using RNA-seq based on next-generation sequencing, the gene expression profiles of immortalized cells are compared with parental cells as well as those immortalized with SV40 large T antigen, which is once a popular method for cellular immortalization. The profiling results show that newly established common minke-whale-derived immortaliozed cells have completely different profiles from SV40 cells. This result indicates that the expression of mutant CDK4, cyclin D1, and TERT enables to establish immortalized cell lines with different biological nature from SV40 expressing cells.

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.

Abstract
Cell line development from shrimp is not a novel venture as researchers across the globe have been trying to have crustacean cell lines over 30 years. The reason for not attaining a crustacean or precisely a shrimp cell line is believed to be the replicative senescence and the inability to maintain telomere length in vitro. Moreover, spontaneous in vitro transformations do not happen in shrimp cells. Oncogenic induction in primary cell culture is one of the ways to attain in vitro transformation by way of disrupting the mechanisms which involve cellular senescence. In this context, a recombinant baculovirus with shrimp viral promoter IHHNV-P2 was used for the transduction aimed at immortalization. An oncogene, H-ras, was successfully amplified and cloned in to the baculoviral vector, downstream to shrimp viral promoter IHHNV-P2 and upstream to GFP. Recombinant baculovirus with H-ras was generated and used for transduction into shrimp lymphoid cells during early dividing stage. Accordingly, fibroblast-like primary cell culture got developed, and H-ras and GFP expression could be confirmed. The study suggests that the simple method of incubating recombinant baculovirus with minced tissue enables in vitro transduction during early dividing stage of the cells, and the transduction efficiency gets enhanced by adding 5 mM sodium butyrate to the culture medium.

Abstract
We previously reported the successful establishment of multiple immortalized cell lines that preserved the original nature of the primary cells via co-expression of R24C mutant cyclin-dependent kinase 4 (CDK4R24C), Cyclin D1, and telomerase reverse transcriptase (TERT). However, as these genes are kind of oncogenes, tools to control their expression levels are favorable. In this study, we describe a new polycistronic lentiviral vector expressing proliferation factors, CDK4R24C and Cyclin D1 along with enhanced green fluorescence protein (EGFP) under the control of doxycycline (Dox)-dependent transactivator (rtTA) and tetracycline response element (TRE). By introducing the Dox-inducible lentiviral vector into human airway epithelial cells, we established a novel human airway epithelial cell line harboring polycistronic Dox-inducible CDK4R24C and Cyclin D1, referred to as Tet-on K4D cells. We showed that the cell growth of Tet-on K4D cells could be controlled by Dox. Furthermore, expression of K4D genes and rtTA gene can be independently monitored by fluorescent imaging. Cultured airway epithelial cells are useful as a tool for studying the pathogenesis of lung disorders. Altogether, our established human airway epithelial cells could be used for a variety of studies such as lung pathology and biology underlying the differentiation process to form the complex pseudostratified multicellular layers.

Abstract
Cellular immortalization enables indefinite expansion of cultured cells. However, the process of cell immortalization sometimes changes the original nature of primary cells. In this study, we performed expression profiling of poly A-tailed RNA from primary and immortalized corneal epithelial cells expressing Simian virus 40 large T antigen (SV40) or the combination of mutant cyclin-dependent kinase 4 (CDK4), cyclin D1, and telomere reverse transcriptase (TERT). Furthermore, we studied the expression profile of SV40 cells cultured in medium with or without serum. The profiling of whole expression pattern revealed that immortalized corneal epithelial cells with SV40 showed a distinct expression pattern from wild-type cells regardless of the presence or absence of serum, while corneal epithelial cells with combinatorial expression showed an expression pattern relatively closer to that of wild-type cells.

Abstract
The immortalized cell is an essential research tool that uses robust growth properties for the functional investigation of gene products. Immortalized mammalian cells have mainly been established using three methods: expression of simian vacuolating virus 40 T antigen (the SV40 method); human papilloma virus-derived oncoprotein E6/E7 (the E6/E7 method); or combinatorial expression of R24C mutant cyclin-dependent kinase 4, cyclin D1, and telomerase reverse transcriptase (the K4DT method). However, it is unclear as to which method is optimal for an in vitro model. Here, we compared the biological characteristics and genome-wide expression profiles of immortalized human dermal papilla cells generated by the SV40, E6/E7, or K4DT method. To our knowledge, this is the first study to comprehensively compare expression profiles to determine the optimal immortalization method for maintaining the original nature of the wild-type cells. These data would be valuable to scientists aiming to establish new immortalized cell lines.

Abstract
Androgenetic alopecia (AGA) is the most common type of hair loss, and is mainly caused by the biological effects of testosterone on dermal papilla cells (DPCs). In vitro culturing of DPCs might be a useful tool for the screening of target molecule of AGA. However, primary DPCs cannot continuously proliferate owing to cellular senescence and cell culture stress. In this study, we introduced mutant cyclin-dependent kinase 4 (CDK4), Cyclin D1, and telomerase reverse transcriptase (TERT) into DPCs. We confirmed protein expression of CDK4 and Cyclin D1, and enzymatic activity of TERT. Furthermore, we found the established cell line was free from cellular senescence. We also introduced the androgen receptor gene using a recombinant retrovirus, to compensate the transcriptional suppressed endogenous androgen receptor in the process of cell proliferation. Furthermore, we detected the efficient nuclear translocation of androgen receptor into the nucleus after the treatment of dihydrotestosterone, indicating the functionality of our introduced receptor. Our established cell line is a useful tool to identify the downstream signaling pathway, which activated by the testosterone.

Orimoto A, Kyakumoto S, Eitsuka T, Nakagawa K, Kiyono T, Fukuda T. Efficient immortalization of human dental pulp stem cells with expression of cell cycle regulators with the intact chromosomal condition. PLoS One 2020; 15:e0229996. [PMID: 32119713 PMCID: PMC7051082 DOI: 10.1371/journal.pone.0229996] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 02/19/2020] [Indexed: 12/23/2022] Open
Abstract
Clinical studies have recently demonstrated that autologous transplantation of mobilized dental pulp stem cells is a safe and efficacious potential therapy for pulp regeneration. However, some limitations need to be addressed, such as the high cost of the safety and quality control tests for isolated individual dental pulp cell products before transplantation. Therefore, more efficient in vitro culturing of human dental pulp stem cells might be useful for providing low cost and high reliability testing for pulp regeneration therapy. In this study, we established a novel immortalized dental pulp stem cell line by co-expressing a mutant cyclin-dependent kinase 4 (CDK4R24C), Cyclin D1, and telomerase reverse transcriptase (TERT). The established cell line maintained its original diploid chromosomes and stemness characteristics and exhibited an enhanced proliferation rate. In addition, we showed the immortalized human dental pulp stem cells still keeps their osteogenic and adipogenic differentiation abilities under appropriate culture conditions even though the cell proliferation was accelerated. Taken together, our established cell lines could serve as a useful in vitro tool for pulp regeneration therapy, and can contribute to reproducibility and ease of cell handling, thereby saving time and costs associated with safety and quality control tests.

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.

BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2019; 1866:945-956.

Abstract
The maintenance of stem cells often requires the support of feeder cells. Primary mouse embryonic fibroblasts (MEFs) have traditionally been used as feeder cells, and although these MEF-derived feeder cells have exhibited a reasonable performance, they require repeated cell isolation, since MEFs cannot expand indefinitely. To overcome this limitation, immortalized cells, such as STO cells, have been used. However, one major disadvantage is that previously reported immortalized cells can only support stem cell cultures for a relatively short period, typically 4 to 7 days. In this study, we found that our newly established rat-derived fibroblasts immortalized by the expression of mutant cyclin-dependent kinase 4, cyclin D, and telomerase reverse transcriptase, can function as feeder cells for relatively long cell culture periods of approximately 14 days. The rat-derived immortalized cells developed in this study should be a useful source of feeder cells to support stem cell research.

Abstract
Although immortalized cultured cells are useful for various functional assays or transcriptome analysis, highly efficient and reproducible immortalization methods have not been developed in avian-derived cells. We introduced the simian virus 40 T antigen (SV40T) and human papillomavirus (HPV)-E6E7 to chick and Okinawa rail (endangered species)derived fibroblast. As a result, neither the SV40T nor E6E7 genes could induce avian cell immortality. Accordingly, we attempted to use a recently developed immortalization method, which involved the coexpression of mutant cyclin-dependent kinase 4 (CDK4), Cyclin D, and TERT (K4DT method) in these avian cells. Although the K4DT method could not efficiently induce the efficient immortalization in mass cell population, cellular division until the senescence was significantly extended by K4DT, we succeeded to obtain the immortalized avian cells (chick K4DT: one clone, Okinawa rail K4DT: three clones, Okinawa rail K4DT + telomerase RNA component: one clone) with K4DT expression. We conclude that K4DT expression is used to extend the cell division and immortalization of avian-derived cells.

Abstract
Tsushima leopard cat is the subspecies of Amur cats, and it is classified as the most highest class of critically endangered animals. Although the protection activity is highly recognized, the number of animals is decreasing due to the human activity and invasion of domestic cats and infectious disease. In this study, we succeeded primary culture of normal fibroblasts derived from the Tsushima leopard cat (Prionailurus bengalensis euptilurus). Furthermore, we introduced the human derived mutant Cyclin Dependent Kinase 4, Cyclin D1, and telomere reverse transcriptase. We showed that the expression of these three genes efficiently immortalized cells derived from Tsushima leopard cat. Furthermore, we showed that the chromosome pattern of the established cells is identical with the original one. These data indicate that our method of immortalization is useful to establish cell lines from critically endangered cats, which potentially contributes to the re-generation of critically endangered animals from cultured cell with reproductive technique, such as somatic cloning.

Abstract
Conservation of the genetic resources of endangered animals is crucial for future generations. The loggerhead sea turtle (Caretta caretta) is a critically endangered species, because of human hunting, hybridisation with other sea turtle species, and infectious diseases. In the present study, we established primary fibroblast cell lines from the loggerhead sea turtle, and showed its species specific chromosome number is 2n = 56, which is identical to that of the hawksbill and olive ridley sea turtles. We first showed that intensive hybridization among multiple sea turtle species caused due to the identical chromosome number, which allows existence of stable hybridization among the multiple sea turtle species. Expressions of human-derived mutant Cyclin-dependent kinase 4 (CDK4) and Cyclin D dramatically extended the cell culture period, when it was compared with the cell culture period of wild type cells. The recombinant fibroblast cell lines maintained the normal chromosome condition and morphology, indicating that, at the G1/S phase, the machinery to control the cellular proliferation is evolutionally conserved among various vertebrates. To our knowledge, this study is the first to demonstrate the functional conservation to overcome the negative feedback system to limit the turn over of the cell cycle between mammalian and reptiles. Our cell culture method will enable the sharing of cells from critically endangered animals as research materials.

Abstract
Gestational trophoblastic diseases (GTDs) are a group of diseases characterized by abnormal cellular proliferation of atypical trophoblasts. A hydatidiform mole is an abnormal pregnancy caused by genetic fertilization disorders, and it can be classified as a complete hydatidiform mole (CHM) or a partial hydatidiform mole. The aim of this study was to establish cell lines from CHMs and to characterize the cells for future studies concerning GTD. HMol1-2C, HMol1-3B, HMol1-8 and HMol3-1B were established from primary cultures of CHM explants following the introduction of different combinations of genes including human telomerase reverse transcriptase (hTERT), a mutant form of CDK (CDK4R24C), cyclin D1, p53C234, MYC and HRAS. HMol1-2C, HMol1-3B, and HMol3-1B were confirmed to originate from trophoblasts of androgenic, homozygous CHMs. These three cell lines exhibited low human chorionic gonadotropin secretion, low migration and invasion abilities, and the potential to differentiate into syncytiotrophoblastic cells via forskolin treatment. These results suggest that these cells exhibit characteristics of trophoblastic cells, especially cytotrophoblastic cells. HMol1-8 was found to consist of diploid cells and originated from maternal cells, suggesting that they were derived from decidual cells. In conclusion, we successfully established three cell lines from CHMs by introduction of hTERT and other genes. Analysis revealed that the genetic origin of each cell line was identical with that of the original molar tissue, and the cell lines exhibited characteristics of trophoblastic cells, which are similar to undifferentiated cytotrophoblasts.

Abstract
The cellular conditions required to establish induced pluripotent stem cells (iPSCs), such as the number of reprogramming factors and/or promoter selection, differ among species. The establishment of iPSCs derived from cells of
previously unstudied species therefore requires the extensive optimization of programming conditions, including promoter selection and the optimal number of reprogramming factors, through a trial-and-error approach. While the four
Yamanaka factors Oct3/4, Sox2, Klf4, and c-Myc are sufficient for iPSC establishment in mice, we reported previously that six reprogramming factors were necessary for the creation of iPSCs from primary prairie vole-derived cells.
Further to this study, we now show detailed data describing the optimization protocol we developed in order to obtain iPSCs from immortalized prairie vole-derived fibroblasts. Immortalized cells can be very useful tools in the
optimization of cellular reprogramming conditions, as cellular senescence is known to dramatically decrease the efficiency of iPSC establishment. The immortalized prairie vole cells used in this optimization were designated K4DT
cells as they contained mutant forms of CDK4, cyclin D, and telomerase reverse transcriptase (TERT). We show that iPSCs derived from these immortalized cells exhibit the transcriptional silencing of exogenous reprogramming factors
while maintaining pluripotent cell morphology. There were no observed differences between the iPSCs derived from primary and immortalized prairie vole fibroblasts. Our data suggest that cells that are immortalized with mutant
CDK4, cyclin D, and TERT provide a useful tool for the determination of the optimal conditions for iPSC establishment.

Abstract
The African savannah elephant (Loxodonta africana) is one of the critically endangered animals. Conservation of genetic and cellular resources is important for the promotion of wild life-related research. Although primary cultured cells are a useful model for the physiology and genomics of the wild-type animals, their distribution is restricted due to the limited number of cell divisions allowed in them. Here, we tried to immortalize a primary cell line of L. africana with by overexpressing human mutant form of cyclin-dependent kinase 4 (CDK4R24C), cyclin D, and telomerase (TERT). It has been shown before that the combination of human CDK4R24C, cyclin D, and TERT induces the efficient cellular immortalization of cells derived from humans, bovine, swine, and monkeys. Interestingly, although the combination of these three genes extended the cellular proliferation of the L. africana-derived cells, they did not induce cellular immortalization. This study suggest that control of cellular senescence in L. africana-derived cells would be different molecular mechanisms compared to those governing human, bovine, swine, and monkey cells.

Abstract
Lowland Anoa has become endangered due to hunting and human activity. Protection and breeding of endangered species in a controlled environment is the best way of conservation. However, it is not possible to adopt this approach for all endangered species because of the cost involved and the ever-increasing number of critically endangered species. In consideration of these limitations to the conventional conservation methods, we established a primary cell culture of endangered buffalo (Lowland Anoa, Bubalus quarlesi), for the preservation of this biological resource. In addition, we introduced human derived, mutant cyclin dependent kinase 4 (CDK4), Cyclin D, and telomerase reverse transcriptase (TERT) into the primary cells. The successful introduction of these three genes was confirmed by western blot with specific antibodies, and enzymatic activity. We also showed that the expression of mutant CDK4, Cyclin D, and TERT allows us to efficiently establish an immortalized cell line, with an intact chromosome pattern, from Lowland Anoa. To the best of our knowledge, this study is the first investigation that established an immortalized cell line of an endangered wild animal species.

Reliable and versatile immortal muscle cell models from healthy and myotonic dystrophy type 1 primary human myoblasts. Exp Cell Res 2016; 342:39-51.

Abstract
Primary human skeletal muscle cells (hSkMCs) are invaluable tools for deciphering the basic molecular mechanisms of muscle-related biological processes and pathological alterations. Nevertheless, their use is quite restricted due to poor availability, short life span and variable purity of the cells during in vitro culture. Here, we evaluate a recently published method of hSkMCs immortalization, relying on ectopic expression of cyclin D1 (CCND1), cyclin-dependent kinase 4 (CDK4) and telomerase (TERT) in myoblasts from healthy donors (n=3) and myotonic dystrophy type 1 (DM1) patients (n=2). The efficacy to maintain the myogenic and non-transformed phenotype, as well as the main pathogenetic hallmarks of DM1, has been assessed. Combined expression of the three genes i) maintained the CD56(NCAM)-positive myoblast population and differentiation potential; ii) preserved the non-transformed phenotype and iii) maintained the CTG repeat length, amount of nuclear foci and aberrant alternative splicing in immortal muscle cells. Moreover, immortal hSkMCs displayed attractive additional features such as structural maturation of sarcomeres, persistence of Pax7-positive cells during differentiation and complete disappearance of nuclear foci following (CAG)7 antisense oligonucleotide (ASO) treatment. Overall, the CCND1, CDK4 and TERT immortalization yields versatile, reliable and extremely useful human muscle cell models to investigate the basic molecular features of human muscle cell biology, to elucidate the molecular pathogenetic mechanisms and to test new therapeutic approaches for DM1 in vitro.

Abstract
Cattle are the economically important animals in human society. They are essential for the production of livestock products such as milk and meats. The production efficiency of livestock products is negatively impacted by infection with zoonotic pathogens. To prevent and control infectious diseases, it is important to understand the interaction between cattle tissue and pathogenic bacteria. In this study, we established an in vitro infection model of an immortalized bovine colon-derived epithelial cell line by transducing the cells with lentiviral vectors containing genes encoding cell cycle regulators cyclin D1, mutant cyclin dependent kinase 4 (CDK4), and human telomerase reverse transcriptase (TERT). The established cell line showed continuous cell proliferation, expression of epithelial markers, and an intact karyotype, indicating that the cells maintained their original nature as colon-derived epithelium. Furthermore, we exposed the established cell line to two strains of Salmonella enterica and EHEC. Interestingly, S. Typhimurium showed higher affinity for the established cell line and invaded the cytoplasm than S. Enteritidis. Quantitative RT-PCR revealed that gene expression of Toll-like receptor 1 (TLR1), TLR 2 and TLR 3, whereas TLR 4, 5 and 6 were not detectable in established cells. Our established immortalized colon-derived epithelial cell should be a useful tool for studies evaluating the molecular mechanisms underlying bacterial infection.

Abstract
The prairie vole (Microtus ochrogaster) shows social behaviors such as
monogamy and parenting of infants with pair bonding. These social behaviors are specific
to the prairie vole and have not been observed in other types of voles, such as mountain
voles. Although the prairie vole has several unique characteristics, an in
vitro cell culture system has not been established for this species.
Furthermore, establishment of cultured cells derived from the prairie vole may be
beneficial based on the three Rs (i.e., Replacement, Reduction, and Refinement) concept.
Therefore, in this study, we attempted to establish an immortalized cell line derived from
the prairie vole. Our previous research has shown that transduction with mutant forms of
cyclin-dependent kinase 4 (CDK4), cyclin D, and telomerase reverse transcriptase (TERT)
could efficiently immortalize cells from multiple species, including humans, cattle, pigs,
and monkeys. Here, we introduced these three genes into prairie vole-derived muscle
fibroblasts. The expression of mutant CDK4 and cyclin D proteins was confirmed by western
blotting, and telomerase activity was detected in immortalized vole muscle-derived
fibroblasts (VMF-K4DT cells or VMFs) by stretch PCR. Population doubling analysis showed
that the introduction of mutant CDK4, cyclin D, and TERT extended the lifespan of VMFs. To
the best of our knowledge, this is the first report describing the establishment of an
immortalized cell line derived from the prairie vole through the expression of mutant
CDK4, cyclin D, and human TERT.
