Nogueira IPM, Costa GMJ, Lacerda SMDSN. Avian iPSC Derivation to Recover Threatened Wild Species: A Comprehensive Review in Light of Well-Established Protocols. Animals (Basel) 2024; 14:220. [PMID: 38254390 PMCID: PMC10812705 DOI: 10.3390/ani14020220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/20/2023] [Accepted: 12/21/2023] [Indexed: 01/24/2024] Open
Abstract
Induced pluripotent stem cells (iPSCs) were first generated by Yamanaka in 2006, revolutionizing research by overcoming limitations imposed by the use of embryonic stem cells. In terms of the conservation of endangered species, iPSC technology presents itself as a viable alternative for the manipulation of target genetics without compromising specimens. Although iPSCs have been successfully generated for various species, their application in nonmammalian species, particularly avian species, requires further in-depth investigation to cover the diversity of wild species at risk and their different protocol requirements. This study aims to provide an overview of the workflow for iPSC induction, comparing well-established protocols in humans and mice with the limited information available for avian species. Here, we discuss the somatic cell sources to be reprogrammed, genetic factors, delivery methods, enhancers, a brief history of achievements in avian iPSC derivation, the main approaches for iPSC characterization, and the future perspectives and challenges for the field. By examining the current protocols and state-of-the-art techniques employed in iPSC generation, we seek to contribute to the development of efficient and species-specific iPSC methodologies for at-risk avian species. The advancement of iPSC technology holds great promise for achieving in vitro germline competency and, consequently, addressing reproductive challenges in endangered species, providing valuable tools for basic research, bird genetic preservation and rescue, and the establishment of cryobanks for future conservation efforts.

Abstract
The validation of the use of primary cell lines from non-lethal matrixes of feathers and blood of nestlings of a wild bird species, the tawny owl (Strix aluco) is described. Tawny Owl Feather Fibroblast (TOFF) cells and peripheral blood mononuclear cells (PBMCs) were isolated and cultured from the pulp of the secondary wing feathers and whole blood respectively from free-living tawny owl nestlings. Cell growth was registered up until 48 h for both the PBMC cells and the TOFFs. The validation of these primary cell lines in free-living birds has the potential to advance the assessment of immunotoxicological effects in wildlife via non-lethal manner. They provide a key tool with which to study cell toxicity and responses to environmental stressors on a cellular level in wild bird species of interest.

Abstract
The creation of a genetic resource bank of avian species aims to prevent the decline and fragmentation of wild bird populations, which in turn lead to the loss of genetic diversity and, in more serious cases, the extinction of the most threatened species. In order for the collected genetic material to be stored in a bank and useful when necessary, it is essential to improve the technique ensuring its effectiveness. Thus, our study used feather follicle cells from the domestic gallus species to standardize the technique of cell culture and subsequent cryopreservation. This study aimed to establish a protocol, in vitro, of isolation and primary culture of somatic cells derived from the feather follicle, with the purpose of establishing a cell lineage, and evaluate its viability for the biobank formation. Developing feathers of gallus domesticus were collected at 12, 21 and 34 days of age. The feathers were morphologically analyzed and then we selected the region of the calamus due to the presence of pulp for cell culture and cryopreservation. The results showed that it is possible to find cells with distinct morphology; cells in elliptical shape with central nucleus also in elliptical shape, cells with shape and round nucleus, cells compatible with the fibers of the barbules, cell agglomerates and cells adhered to the bottom of the plate with fibroblastatoid shape. After 24 hours of culture there was the presence of primary culture with 80% of confluence and after cryopreservation the average viability after freezing was 68.8%, with cellular morphologies being maintained. Therefore, we proved the isolation of somatic cells from the follicle of bird's feathers, suggesting that this is a source of great value, viable and effective for obtaining biological material for the elaboration of a biobank.

Abstract
The skin is a natural target of stem cell research because of its large size and easy accessibility. Cutaneous mesenchymal stem cells have shown to be a promising source of various adult stem cell or progenitor cell populations, which provide an important source of stem cell-based investigation. Nowadays, much work has been done on dermal-derived mesenchymal stem cells (DMSCs) from humans, mice, sheep, and other mammals, but the literature on avian species has been rarely reported. As an animal model, the goose is an endemic species abounding in dermal tissues which is important in the global economy. In this study, we isolated and established the mesenchymal stem cell line from dermis tissue of goose, which were subcultured to passage 21 in vitro without loss of their functional integrity in terms of morphology, renewal capacity, and presence of mesenchymal stem cell markers. Cryopreservation and resuscitation were also observed in different passages. To investigate the biological characteristics of goose DMSCs, immunofluorescence, reverse transcription-polymerase chain reaction, and flow cytometry were used to detect the characteristic surface markers. Growth curves and the capacity of colony forming were performed to test the self-renew and proliferative ability. Furthermore, the DMSCs are induced to osteoblasts, adipocytes, and chondrocytes in vitro. Our results suggest that DMSCs isolated from goose embryos possess similar biological characteristics to those from other species. The methods in establishment and cultivation of goose DMSCs line demonstrated a good self-renew and expansion potential in vitro, which provided a technological platform for preserving the valuable genetic resources of poultry and a great inspiration for in vitro investigation of avian MSCs.

Abstract
Pluripotent stem cells including embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC) are regarded as representative tools for conservation of animal genetic resources. Although ESC have been established from chicken, it is very difficult to obtain enough embryos for isolation of stem cells for avian conservation in most wild birds. Therefore, the high feasibility of obtaining the pluripotent cell is most important in avian conservation studies. In this study, we generated induced pluripotent stem cell-like cells (iPSLC) from avian Feather Follicular cells (FFC). Avian FFC are one of the most easily accessible cell sources in most avian species, and their reprogramming into pluripotent stem cells can be an alternative system for preservation of avian species. Intriguingly, FFC had mesenchymal stromal cells (MSC)-like characteristics with regard to gene expression, protein expression, and adipocyte differentiation. Subsequently, we attempted to generate iPSLC from FFC using retroviral vectors. The FFC-iPSLC can proliferate with the stem pluripotent property and differentiate into several types of cells in vitro. Our results suggest that chicken FFC are an alternative cell source for avian cell reprogramming into pluripotent stem cells. This experimental strategy should be useful for conservation and restoration of endangered or high-value avian species without sacrificing embryos.

Abstract
More than a decade has now passed since the birth of the first endangered species produced from an adult somatic cell reprogrammed by somatic cell nuclear transfer. At that time, advances made in domestic and laboratory animal species provided the necessary foundation for attempting cutting-edge technologies on threatened and endangered species. In addition to nuclear transfer, spermatogonial stem cell transplantation and induction of pluripotent stem cells have also been explored. Although many basic scientific questions have been answered and more than 30 wild species have been investigated, very few successes have been reported. The majority of studies document numerous obstacles that still need to be overcome to produce viable gametes or embryos for healthy offspring production. This chapter provides an overview of somatic cell and stem cell technologies in different taxa (mammals, fishes, birds, reptiles and amphibians) and evaluates the potential and impact of these approaches for animal species conservation.

Abstract
Feather follicles have the extraordinary ability to regenerate and undergo molting cycles. Being tissue-specific stem cells, feather follicle stem cells (FFSCs) have a strong capacity for proliferation and are presumed to be progenitor cells for various epidermal organs. In order to characterize FFSCs and to understand how the feather epidermis and FFSCs produce such a reliable differentiation program resulting in the formation of complex feathers, We developed a culture scheme to select and expand FFSCs from chick feather follicles. FFSCs were examined with cell profiles, mutilpotential differentiation and immunocytochemical staining. FFSCs from a single clone were capable of self-renewal and proliferation. These cells expressed integrin β1, CD49c, cytokeratin 15 (K15), cytokeratin 19 (K19) and a neural-genic cell marker, nestin, but not a teminal differentiation-related keratinocyte marker, cytokeratin 10 (K10). FFSCs could trans-differentiate into adipocytes, neurocytes and keratinocytes. The formation of micro-feather like structures ex-vivo also revealed the potential of regeneration. These results demonstrate that FFSCs possess the properties of stem/progenitor cells and may therefore serve as a useful model for studying mechanisms of stem cell differentiation and their involvement in organ regeneration.

Abstract
Normal somatic cells possess a finite life span owing to replicative senescence. Telomerase functions as a potential regulator of senescence in various cells. Expression level of human telomerase reverse transcriptase (hTERT) is correlated with telomerase activity and cellular immortalization. In this study, we investigated the effects of ectopic expression of hTERT on proliferation potential of chicken feather keratinocyte stem cells (FKSCs). We established FKSCs transduced with hTERT catalytic subunit fused with EGFP marker gene (hTERT-EGFP-FKSCs). hTERT-EGFP-FKSCs had the great potential of proliferation in vitro and expressed kerainocyte stem cell markers integrin beta1 and CD49c. Keratin 15 and keratin 19, as native FKSCs, were also detected in hTERT-EGFP-FKSCs. By the analysis of fluorescent RT-PCR, western blotting and TRAP assay, hTERT-EGFP-FKSCs were positive for telomerase activity, in comparison with native FKSCs showing no telomerase activity. We demonstrated that ectopic expression of hTERT could result in immortalization of FKSCs. Tumorigenecity of hTERT-EGFP-FKSCs were examined by soft agar assay and transplantation into NOD-SCID mice. Results showed that hTERT-EGFP-FKSCs sustained the cellular characteristics of native FKSCs and had no transforming activity. In vivo differentiation multipotentials of hTERT-EGFP-FKSCs were confirmed by transplantation into developing chicken embryos and in situ hybridization analysis. These data provide a novel framework for understanding human telomerase activity in different species and suggest a new insight for manipulating hTERT for therapeutic purposes in treating tissue injury and aging.

Abstract
Gene silencing using small interfering RNA (siRNA) may be useful for functional analyses of unidentified genes expressed during cell differentiation. The present study was performed to evaluate RNA interference (RNAi) in porcine granulosa cells stimulated with bovine FSH, by using two fluorescence reporter genes: a plasmid encoding green fluorescent protein (GFP) and a plasmid encoding red fluorescent protein (RFP). The siRNA targeting GFP mRNA sequence (GFP-siRNA) with both plasmids was introduced into cultured cells by lipofection. GFP- and RFP-expressing cells were observed under fluorescence microscopy and analyzed by flow cytometry. Strong fluorescence was observed after introduction of both plasmids into cells. The intensity of green fluorescence generated by GFP was greatly suppressed by introduction of GFP-siRNA, showing an approximate 70% decrease in the ratio of green to red fluorescence. Consequently, we concluded that gene silencing by siRNA can be used to analyze the functions of genes of interest during differentiation of porcine granulosa cells.
