Abstract
We studied ante- and postnatal development of the offspring of intact female rats crossed with males injected with low doses of methotrexate 3 and 6 months before mating. The time of crossing corresponded to the manifestation of the cytostatic effect on spermatogonial stem cells. The offspring of methotrexate-treated males was characterized by increased preimplantation losses and fetal growth restriction in the antenatal period and inhibition of physical development, delayed formation of sensory-motor reflexes, and impaired learning abilities in the postnatal period.

Abstract
Regenerative medicine has been shown to hold enormous potential to treat traumatic and degenerative diseases, and substantial advancements have been made in the recent decades. In particular, different cell types were evaluated in basic research and preclinical studies on cell-based therapy applications. Despite the extraordinary achievements made in experimental studies and clinical practice, a considerable number of obstacles, such as the cellular source, ethical and safety issues, hinder further clinical applications. Spermatogonial stem cells (SSCs) are gradually becoming the research focus of cell-based regenerative medicine owing to their unique merits over other types of stem cells, particularly the lack of ethical concerns and lower immunogenicity. In addition, SSCs have been successfully induced to differentiate into other cell types under different appropriate conditions in compelling studies. Based on these properties, we systemically reviewed the development of SSCs as an attractive cell source for cell-based regenerative medicine.

Characterization of Human Mesenchymal Stem Cells Isolated from the Testis. Stem Cells Int 2018; 2018:4910304.

Abstract
Mesenchymal stem cells hold great promise for regenerative medicine as they can be easily isolated from different sources such as adipose tissue, bone marrow, and umbilical cord blood. Spontaneously arising pluripotent stem cells can be obtained in culture from murine spermatogonial stem cells (SSCs), while the pluripotency of the human counterpart remains a matter of debate. Recent gene expression profiling studies have demonstrated that embryonic stem cell- (ESC-) like cells obtained from the human testis are indeed closer to mesenchymal stem cells (MSCs) than to pluripotent stem cells. Here, we confirm that colonies derived from human testicular cultures, with our isolation protocol, are of mesenchymal origin and do not arise from spermatogonial stem cells (SSCs). The testis, thus, provides an important and accessible source of MSCs (tMSCs) that can be potentially used for nephrotoxicity testing in vitro. We further demonstrate, for the first time, that tMSCs are able to secrete microvesicles that could possibly be applied to the treatment of various chronic diseases, such as those affecting the kidney.

Abstract
Stem cell research for treating or curing ischemic heart disease has, till date, culminated in three basic approaches: the use of induced pluripotent stem cell (iPSC) technology; reprogramming cardiac fibroblasts; and cardiovascular progenitor cell regeneration. As each approach has been shown to have its advantages and disadvantages, exploiting the advantages while minimizing the disadvantages has been a challenge. Using human germline pluripotent stem cells (hgPSCs) along with a modified version of a relatively novel cell-expansion culture methodology to induce quick, indefinite expansion of normally slow growing hgPSCs, it was possible to emphasize the advantages of all three approaches. We consistently found that unipotent germline stem cells, when removed from their niche and cultured in the correct medium, expressed endogenously, pluripotency genes, which induced them to become hgPSCs. These cells are then capable of producing cell types from all three germ layers. Upon differentiation into cardiac lineages, our data consistently showed that they not only expressed cardiac genes, but also expressed cardiac-promoting paracrine factors. Taking these data a step further, we found that hgPSC-derived cardiac cells could integrate into cardiac tissue in vivo. Note, while the work presented here was based on testes-derived hgPSCs, data from other laboratories have shown that ovaries contain very similar types of stem cells that can give rise to hgPSCs. As a result, hgPSCs should be considered a viable option for eventual use in patients, male or female, with ischemic heart disease

Abstract
Artificial chromosomes are useful in making functional vectors for very large genes, studying chromosome physiology, and modeling chromosomal disorders. Shinohara et al. have succeeded for the first time in creating transchromosomic mice by manipulating spermatogonial stem cells (SSCs), which exhibited superior chromosomal stability compared with embryonic stem cells (ESCs).

Abstract
Geminin plays a critical role in cell cycle regulation by regulating DNA replication and serves as a transcriptional molecular switch that directs cell fate decisions. Spermatogonia lacking Geminin disappear
during the initial wave of mitotic proliferation, while geminin is not required for meiotic progression of spermatocytes. It is unclear whether geminin plays a role in pre-meiotic DNA replication in later-stage spermatogonia and
their subsequent differentiation. Here, we selectively disrupted Geminin in the male germline using the Stra8-Cre/loxP conditional knockout system.
Geminin-deficient mice showed atrophic testes and infertility, concomitant with impaired spermatogenesis and reduced sperm motility. The number of undifferentiated spermatogonia and spermatocytes was significantly
reduced; the pachytene stage was impaired most severely. Expression of cell proliferation-associated genes was reduced in Gmnnfl/Δ; Stra8-Cre testes compared to in controls. Increased
DNA damage, decreased Cdt1, and increased phosphorylation of Chk1/Chk2 were observed in Geminin-deficient germ cells. These results suggest that geminin plays important roles in pre-meiotic DNA replication and
subsequent spermatogenesis.

Abstract
Spermatogonial stem cells (SSCs) provide the foundation for spermatogenesis and fertility throughout the adult life of a male. Genetic manipulations of SSCs combined with germ cell transplantation present a novel approach for gene therapy and production of genetically modified animals. However, the rarity of SSCs within mammalian testes remains an impediment to related applications, making in vitro expansion of SSCs a prerequisite. Nevertheless, long-term culture systems of SSCs from large animals have not been established yet. In this study, we developed an optimized in vitro culture condition for porcine undifferentiated spermatogonia. The germ cells were isolated and enriched from 7-day-old porcine testes by an optimized differential planting. We tested different feeder layers and found that neonatal autologous Sertoli cells acted better than the SIM mouse embryo-derived thioguanine- and ouabain-resistant (STO) cell line and adult Sertoli cells. The effects of several growth factors were also investigated. Using neonatal Sertoli cells as feeder and Dulbecco's modified eagle medium: nutrient mixture F-12 (DMEM/F12) culture medium supplemented with 10% KSR and four cytokines, the undifferentiated spermatogonia can proliferate in vitro for at least 2 months without loss of stemness. The expression of SSC markers indicated that the cultured cells maintained SSC expression profiles. Moreover, xenotransplantation and in vitro induction showed that the long-term cultured cells preserved the capacity to colonize in vivo and differentiate in vitro, respectively, demonstrating the presence of SSCs in the cultured cells. In conclusion, the conditions described in this study can support the normal proliferation of porcine undifferentiated spermatogonia with stemness and normal karyotype for at least 2 months. This culture system will serve as a basic refinement in the future studies and facilitate studies on SSC biology and genetic manipulation of male germ cells.
