Abstract
Meat and eggs from chicken are the major source of animal protein for the human population. The cryopreservation of poultry species is needed to guarantee sustainable production. Here, we describe the existing cryopreservation technologies for avian reproductive cells using embryonic germ cells, spermatozoa and ovarian tissues. We outline strategies to reconstitute chicken breeds from their cryopreserved embryonic germ cells using surrogate hosts and discuss the perspectives for genetic conservation and reconstitution of chicken and wild avian species using surrogate host animals.

Formation, Application, and Significance of Chicken Primordial Germ Cells: A Review. Animals (Basel) 2023; 13:ani13061096. [PMID: 36978637 PMCID: PMC10044044 DOI: 10.3390/ani13061096] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/11/2023] [Accepted: 03/13/2023] [Indexed: 03/22/2023] Open
Abstract
Chicken is one of the most widely consumed sources of protein globally. Primordial germ cells (PGCs) are the precursors for ova and sperm. One of the early embryogenesis events in most animals is the segregation of the somatic and germ lineages. PGC cultures occur in the germline, and PGCs are less studied in many species. It is relatively challenging to separate, cultivate, and genetically alter chicken without mutating the basic germline. The present study aims to gather previous research about chicken PGCs and provide a customized review of studies and developments in the field of PGCs, especially for avian species. Furthermore, we show that the propagation of chicken PGCs into embryonic germ cells that contribute to somatic tissues may be produced in vitro. Primordial germ cells offer an ideal system in developmental biology, as these cells play a vital role in the genetic modification and treatment of infertility. Cryopreservation helps to maintain genetic resources and sustainable production in the poultry industry. Keeping in mind the significance of cryopreservation for storage and gametogenesis, we discuss its role in the preservation of primordial germ cells. Transgenesis and genetic modifications in chicken lead to the development of various medicinal chicken varieties and aid in improving their production and quality for consumption purposes. Additionally, these characteristics open up new possibilities for modifying the chicken genome for agricultural and medical purposes.

Abstract
Primordial germ cells (PGCs) are precursor cells of sperm and eggs. The fate decisions of chicken PGCs in terms of their development, integrity, and sex determination have unique features, thereby providing insights into evolutionary developmental biology. Additionally, fate decisions in the context of a self-renewal mechanism have been applied to establish culture protocols for chicken PGCs, enabling the production of genome-edited chickens and the conservation of genetic resources. Thus, studies on the fate decisions of chicken PGCs have significantly contributed to both academic and industrial development. Furthermore, studies on fate decisions have rapidly advanced owing to the recent development of essential research technologies, such as genome editing and RNA sequencing. Here, we reviewed the status of fate decisions of chicken PGCs and provided insight into other important research issues that require attention.

Abstract
In birds, sex is determined through cell-autonomous mechanisms and various factors, such as the dosage of DMRT1. While the sex-determination mechanism in gonads is well known, the mechanism in germ cells remains unclear. In this study, we explored the gene expression profiles of male and female primordial germ cells (PGCs) during embryogenesis in chickens to predict the mechanism underlying sex determination. Male and female PGCs were isolated from blood and gonads with a purity > 96% using flow cytometry and analyzed using RNA-seq. Prior to settlement in the gonads, female circulating PGCs (cPGCs) obtained from blood displayed sex-biased expression. Gonadal PGCs (gPGCs) also exhibited sex-biased expression, and the number of female-biased genes detected was higher than that of male-biased genes. The female-biased genes in gPGCs were enriched in some metabolic processes. To reveal the mechanisms underlying the transcriptional regulation of female-biased genes in gPGCs, we performed stimulation tests. Retinoic acid stimulation of cultured gPGCs derived from male embryos resulted in the upregulation of several female-biased genes. Overall, our results suggest that sex determination in avian PGCs involves aspects of both cell-autonomous and somatic-cell regulation. Moreover, it appears that sex determination occurs earlier in females than in males.

Abstract
Chickens are an important resource for smallholder farmers who raise locally adapted, genetically distinct breeds for eggs and meat. The development of efficient reproductive technologies to conserve and regenerate chicken breeds safeguards existing biodiversity and secures poultry genetic resources for climate resilience, biosecurity, and future food production. The majority of the over 1600 breeds of chicken are raised in low and lower to middle income countries under resource-limited, small-scale production systems, which necessitates a low-tech, cost-effective means of conserving diversity is needed. Here, we validate a simple biobanking technique using cryopreserved embryonic chicken gonads. The gonads are quickly isolated, visually sexed, pooled by sex, and cryopreserved. Subsequently, the stored material is thawed and dissociated before injection into sterile host chicken embryos. By using pooled GFP and RFP-labelled donor gonadal cells and Sire Dam Surrogate mating, we demonstrate that chicks deriving entirely from male and female donor germ cells are hatched. This technology will enable ongoing efforts to conserve chicken genetic diversity for both commercial and smallholder farmers, and to preserve existing genetic resources at poultry research facilities.

Abstract
CRISPR/Cas9 system genome editing is revolutionizing genetics research in a wide spectrum of animal models in the genetic era. Among these animals, is the poultry species. CRISPR technology is the newest and most advanced gene-editing tool that allows researchers to modify and alter gene functions for transcriptional regulation, gene targeting, epigenetic modification, gene therapy, and drug delivery in the animal genome. The applicability of the CRISPR/Cas9 system in gene editing and modification of genomes in the avian species is still emerging. Up to date, substantial progress in using CRISPR/Cas9 technology has been made in only two poultry species (chicken and quail), with chicken taking the lead. There have been major recent advances in the modification of the avian genome through their germ cell lineages. In the poultry industry, breeders and producers can utilize CRISPR-mediated approaches to enhance the many required genetic variations towards the poultry population that are absent in a given poultry flock. Thus, CRISPR allows the benefit of accessing genetic characteristics that cannot otherwise be used for poultry production. Therefore CRISPR/Cas9 becomes a very powerful and robust tool for editing genes that allow for the introduction or regulation of genetic information in poultry genomes. However, the CRISPR/Cas9 technology has several limitations that need to be addressed to enhance its use in the poultry industry. This review evaluates and provides a summary of recent advances in applying CRISPR/Cas9 gene editing technology in poultry research and explores its potential use in advancing poultry breeding and production with a major focus on chicken and quail. This could aid future advancements in the use of CRISPR technology to improve poultry production.

Abstract
Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

Abstract
The majority of poultry genetic resources are maintained in situ in living populations. However, in situ conservation of poultry genetic resources always carries the risk of loss owing to pathogen outbreaks, genetic problems, breeding cessation, or natural disasters. Cryobanking of germplasm in birds has been limited to the use of semen, preventing conservation of the W chromosome and mitochondrial DNA. A further challenge is posed by the structure of avian eggs, which restricts the cryopreservation of ova and fertilized embryos, a technique widely used for mammalian species. By using a unique biological property and accessibility of avian primordial germ cells (PGCs), precursor cells for gametes, which temporally circulate in the vasculature during early development, an avian PGC transplantation technique has been established. To date, several techniques for PGC manipulation including purification, cryopreservation, depletion, and long-term culture have been developed in chickens. PGC transplantation combined with recent advanced PGC manipulation techniques have enabled ex situ conservation of poultry genetic resources in their complete form. Here, the updated technologies for avian PGC manipulation are introduced, and then the concept of a poultry PGC-bank is proposed by considering the biological properties of avian PGCs.

Abstract
Avian cell lines derived from germinal crescent primordial germ cells and gonadal gonocytes with long-term proliferative capacity in vitro and their subsequent rates of colonization and germline transmission are described. In general, male cultures proliferate more rapidly than female cultures although both can be developed into cell lines of >2 × 10(6) cells, at which time, they can be grown indefinitely and a cell bank can be established. All the cell lines injected into embryos transmitted through the germline with the percentage of germline transmission of both male and female cell lines varying from single digits to the high 90s. The derivation of these primordial germ cell and gonadal cell lines and the subsequent robustness of germline transmission validates these cells as suitable for establishment of lines of chickens bearing novel genetic modifications.

Abstract
Replication-defective retroviral or lentiviral vectors have been used for the production of transgenic animals. Chicken primordial germ cells (PGCs) are the precursors for ova and spermatozoa. Here, we describe the production of transgenic chickens via a germline transmission system using PGCs infected with a replication-defective lentiviral vector. PGCs were sorted with a fluorescence-activated cell sorter based on the expression of stage-specific embryonic antigen-1 from 2.5- and 5.5-day embryos. PGCs from both stages of embryo were infected with a lentiviral vector at a similar efficiency in vitro. PGCs were then transferred into the bloodstream of 2.5-day recipient embryos. The efficiency with which the PGCs were delivered and settled in the gonads was lower for PGCs from 5.5-day embryos than those from 2.5-day embryos when a limited number of PGCs was transferred, while the difference was not obvious upon the transfer of increased number of cells. Using a high number of 5.5-day PGCs infected with a lentiviral vector, transgenic chimeras (G(0)) with an acceptable efficiency for germline transmission were obtained. G(0) female chickens produced transgenic progeny (G(1)) with higher efficiency compared to G(0) male chickens. In G(1) transgenic chickens obtained by this method, enhanced green fluorescent protein was effectively expressed under the control of the actin promoter.

Abstract
A novel method was developed to isolate chick primordial germ cells (PGCs) from circulating embryonic blood. This is a very simple and rapid method for the isolation of circulating PGCs (cPGCs) using an ammonium chloride-potassium (ACK) buffer for lysis of the red blood cells. The PGCs were purified as in vitro culture proceeded. Most of the initial red blood cells were removed in the first step using the ACK lysis buffer. The purity of the cPGCs after ACK treatment was 57.1%, and the recovery rate of cPGCs from whole blood was 90.3%. The ACK process removed only red blood cells and it did not affect cPGC morphology. In the second step, the red blood cells disappeared as the culture progressed. At 7 days of in vitro culture, the purity of the PGCs was 92.9%. Most of these cells expressed germline-specific antibodies, such as those against chicken vasa homolog (CVH). The cultured PGCs expressed the Cvh and Dazl genes. Chimeric chickens were produced from these cultured PGCs, and the donor cells were detected in the gonads, suggesting that the PGCs had biological function. In conclusion, this novel isolation system for PGCs should be easier to use than previous methods. The results of the present study suggest that this novel method will become a powerful tool for germline manipulation in the chicken.
