Abstract
The germline cells are essential for the propagation of human beings, thus essential for the survival of mankind. The germline stem cells, as a unique cell type, generate various states of germ stem cells and then differentiate into specialized cells, spermatozoa and ova, for producing offspring, while self-renew to generate more stem cells. Abnormal development of germline stem cells often causes severe diseases in humans, including infertility and cancer. Primordial germ cells (PGCs) first emerge during early embryonic development, migrate into the gentile ridge, and then join in the formation of gonads. In males, they differentiate into spermatogonial stem cells, which give rise to spermatozoa via meiosis from the onset of puberty, while in females, the female germline stem cells (FGSCs) retain stemness in the ovary and initiate meiosis to generate oocytes. Primordial germ cell-like cells (PGCLCs) can be induced in vitro from embryonic stem cells or induced pluripotent stem cells. In this review, we focus on current advances in these embryonic and adult germline stem cells, and the induced PGCLCs in humans, provide an overview of molecular mechanisms underlying the development and differentiation of the germline stem cells and outline their physiological functions, pathological implications, and clinical applications.

Lee BR, Rengaraj D, Choi HJ, Han JY. A novel F-box domain containing cyclin F like gene is required for maintaining the genome stability and survival of chicken primordial germ cells. FASEB J 2019; 34:1001-1017. [PMID: 31914591 DOI: 10.1096/fj.201901294r] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2019] [Revised: 10/25/2019] [Accepted: 11/07/2019] [Indexed: 12/13/2022]
Abstract
The stability and survival of germ cells are controlled by the germline-specific genes, however, such genes are less known in the avian species. Using a microarray-based the National Center for Biotechnology Information Gene Expression Omnibus dataset, we found an unigene (Gga.9721) that upregulated in the chicken primordial germ cells (PGCs). The unigene showed 97% identities with an uncharacterized chicken cyclin F like gene. The predicted chicken cyclin F like gene was further characterized through expression and regulation in the chicken PGCs. The sequence analysis revealed that the gene shows identities with cyclin F gene and contains an F-box domain. The expression of chicken cyclin F like was detected specifically in the gonads, PGCs, and germline cells. The knockdown of cyclin F like gene resulted in DNA damage and apoptosis in the PGCs. The genes related to stemness and germness were downregulated, whereas, genes related to apoptosis and DNA damage response were increased in the PGCs after the knockdown of chicken cyclin F like. We further observed that the Nanog homeobox controlled the transcriptional activity of chicken cyclin F like gene in PGCs. Collectively, the chicken cyclin F like gene, which is not reported in any other species, is required for maintaining the genome stability of germ cells.

Dev Biol 2019; 455:32-41.

Abstract
The differentiation of primordial germ cells (PGCs) is a fundamental step in development. PR domain-containing protein 14 (PRDM14) and B lymphocyte-induced maturation protein 1 (BLIMP1) play pivotal roles in mouse PGC specification. In the present study, we assessed the roles of chicken orthologs of PRDM14 and BLIMP1 in PGC development. PRDM14 and BLIMP1 were expressed in blastodermal cells and PGCs. The in vivo knockdown of PRDM14 or BLIMP1 by introducing a replication-competent retroviral vector expressing shRNAs to the blastodermal stage of embryos reduced the number of SSEA-1 or chicken vasa homologue-positive PGCs on day 5.5-6.5. Since the inhibition of Activin receptor-like kinase 4/5/7 in cultured PGCs reduced the expression of PRDM14, BLIMP1, and NANOG, and that of MEK inhibited PRDM14 expression, the expression of these genes seems to be controlled by Activin A and FGF2 signaling. Overall, PRDM14, BLIMP1, and NANOG seem to be involved in the self-renewal of PGCs in cultured PGCs and embryos.

J Cell Biochem 2018; 119:4435-4446. [PMID: 29143989 DOI: 10.1002/jcb.26528] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2017] [Accepted: 11/13/2017] [Indexed: 12/31/2022]
Abstract
Nanos2 is an evolutionarily conserved RNA-binding protein containing 2 CCHC-type zinc finger motives. Here, we report that Nanos2 is strongly expressed in the testis compared to other tissues in chicken (Gallus gallus). Overexpression and knockout plasmid vectors were constructed, and in-vitro Cas9/gRNA digestion and T7 endonuclease I (T7E1) assay indicated that Nanos2-g1 possessed the highest knockout activity. In vitro and in vivo, Nanos2 overexpression accelerated the production of embryoid bodies (EBs) and SSC-like cells and promoted cvh, c-kit, and integrin α6 expression. Immunofluorescence staining, periodic acid schiff (PAS) and flow cytometry (FCM) assay showed that primordial germ cells (PGCs) and spermatogonial stem cells (SSCs) formation were significantly promoted. On the contrary, Nanos2 knockout delayed the production of EBs and SSC-like cells and correspondingly reduced cvh, c-kit, and integrin α6 expression. Simultaneously, the quantity of PGCs and SSCs was blocked. Collectively, these results uncovered a novel function of Nanos2 involved in chicken male germ cell differentiation, where it acts as a facilitator.
