Abstract
Substantial improvements in cancer treatment have resulted in longer survival and increased quality of life in cancer survivors with minimized long-term toxicity. However, infertility and gonadal dysfunction continue to be recognized as adverse effects of anticancer therapy. In particular, alkylating agents and irradiation induce testicular damage that results in prolonged azoospermia. Although damage to and recovery of spermatogenesis after cancer treatment have been extensively studied, there is little information regarding the role of differences in testicular immunology in cancer treatment-induced male infertility. In this review, we briefly summarize available rodent and human data on immunological differences in chemotherapy or radiotherapy.

Abstract
Several different strategies have been adopted in attempt to recover from chemotherapy-damaged spermatogenesis that is often seen in oncologic patients. In this study, we have evaluated the impact of short period of exposure to busulphan on the haemogram and seminiferous epithelium of adult rats, focusing on spermatogonial depletion and Sertoli cell (SC) integrity. We then examined whether vitamin B12 supplementation improves the haematological parameters and spermatogonia number. The animals received 10 mg/kg of busulphan (BuG) or busulfan+vitamin B12 (Bu/B12 G) on the first and fourth days of treatment. In H.E.-stained testicular sections, the areas of the seminiferous tubule (ST) and seminiferous epithelium were measured. The number of spermatogonia in H.E-stained and PCNA-immunolabelled testicular sections was quantified. The frequency of tubules with abnormal SC nuclei or TUNEL-positive SC was evaluated. Vimentin immunofluorescence in ST was also evaluated. In BuG and Bu/B12 G, the animals showed leukopenia and thrombocytopenia, but the body weight reduced only in BuG. The areas of ST and seminiferous epithelium decreased in Bu/B12 G and BuG. In BuG, the number of H.E.-stained and PCNA-immunolabelled spermatogonia reduced significantly. The frequency of tubules containing abnormal SC nuclei and TUNEL-positive SC increased and the vimentin immunoexpression pattern changed. In Bu/B12 G, the number of H.E.-stained or PCNA-immunolabelled spermatogonia increased fourfold in comparison with BuG. The structural changes in ST after 6 days of busulphan exposure may be associated with the potential effect of this anti-neoplastic agent on SC. The increased number of spermatogonia in the busulphan-treated animals receiving vitamin B12 indicates that this vitamin can be an adjuvant therapy to improve the fertility in male cancer patients.

Intraovarian transplantation of primordial follicles fails to rescue chemotherapy injured ovaries. Sci Rep 2013; 3:1384.

Abstract
Busulfan and cyclophosphamide (B/C)-treated mice exhibited a marked increase in apoptosis and a concomitant decrease in the ovarian weight. Histological and RT-PCR analysis indicate that the period of germ cell depletion in the B/C-treated ovaries coincides with decreased expression of genes Figla, Lhx8, Nobox, c-kit, and Sox3. However, depletion of the ovarian germ cells is mediated by autophagy-independent pathways that involve Fas/FasL-, TNF-, and/or p53-signalings. Treatment with B/C resulted in the cease of the reproductive function to produce their offspring during the 15(th) week post-treatment period in female mice. Furthermore, injection of the 3 × 10(6) GFP positive primordial follicles into the ovaries of the B/C treated mouse did not show apparent colonization of the transplanted follicles within the recipient ovaries. The present results suggest that B/C treatment is closely associated with an increased risk of premature ovarian failure.

Abstract
The central tenet of ovarian biology, that the oocyte reserve in adult female mammals is finite, has been challenged over recent years by proponents of neo-oogenesis, who claim that germline stem cells exist in the ovarian surface epithelium or the bone marrow. Currently opinion is divided over these claims, and further scrutiny of the evidence advanced in support of the neo-oogenesis hypothesis is warranted - especially in view of the enormous implications for female fertility and health. This article contributes arguments against the hypothesis, providing alternative explanations for key observations, based on published data. Specifically, DNA synthesis in germ cells in the postnatal mouse ovary is attributed to mitochondrial genome replication, and to DNA repair in oocytes lagging in meiotic progression. Lines purported to consist of germline stem cells are identified as ovarian epithelium or as oogonia, from which cultures have been derived previously. Effects of ovotoxic treatments are found to negate claims for the existence of germline stem cells. And arguments are presented for the misidentification of ovarian somatic cells as de novo oocytes. These clarifications, if correct, undermine the concept that germline stem cells supplement the oocyte quota in the postnatal ovary; and instead comply with the theory of a fixed, unregenerated reserve. It is proposed that acceptance of the neo-oogenesis hypothesis is erroneous, and may effectively impede research in areas of ovarian biology. To illustrate, a novel explanation that is consistent with orthodox theory is provided for the observed restoration of fertility in chemotherapy-treated female mice following bone marrow transplantation, otherwise interpreted by proponents of neo-oogenesis as involving stimulation of endogenous germline stem cells. Instead, it is proposed that the chemotherapeutic regimens induce autoimmunity to ovarian antigens, and that the haematopoietic chimaerism produced by bone marrow transplantation circumvents activation of an autoreactive response, thereby rescuing ovarian function. The suggested mechanism draws from animal models of autoimmune ovarian disease, which implicate dysregulation of T cell regulatory function; and from a surmised role for follicular apoptosis in the provision of ovarian autoantigens, to sustain self-tolerance during homeostasis. This interpretation has direct implications for fertility preservation in women undergoing chemotherapy.

Abstract
Previously, we have successfully produced nine cloned piglets using Duroc donor cells. Among these clones, one showed distinct depigmentation of the skin and hair color during puberty. In this study, we selected a clone with depigmentation to investigate the etiology of the anomaly in somatic cell nuclear transfer. We hypothesized that genes related to Waardenburg syndrome (Mitf, Pax-3, Sox-10, Slug, and Kit) are closely associated with the depigmentation of pig, which was derived from somatic cell nuclear transfer (scNT). Total RNA was extracted from the ear tissue of affected and unaffected scNT-derived pigs, and the transcripts encoding Mitf, Pax-3, Sox-10, and Slug, together with the Kit gene, were amplified by reverse transcription-polymerase chain reaction, sequenced, and analyzed. The cDNA sequences from the scNT pig that showed progressive depigmentation did not reveal a mutation in these genes. Although we did not find any mutations in these genes, expression of the genes implicated in Waardenburg syndrome was severely down-regulated in the affected scNT pig when compared with unaffected scNT pigs. This down-regulation of gene expression may result in a previously undescribed phenotype that shows melanocyte instability, leading to progressive loss of pigmentation.

Abstract
Somatic cell nuclear transfer (scNT) is a useful way to create cloned animals. However, scNT clones exhibit high levels of phenotypic instability. This instability may be due to epigenetic reprogramming and/or genomic damage in the donor cells. To test this, we produced transgenic pig fibroblasts harboring the truncated human thrombopoietin (hTPO) gene and used them as donor cells in scNT to produce first-generation (G1) cloned piglets. In this study, 2,818 scNT embryos were transferred to 11 recipients and five G1 piglets were obtained. Among them, a clone had a dimorphic facial appearance with severe hypertelorism and a broad prominent nasal bridge. The other clones looked normal. Second-generation (G2) scNT piglets were then produced using ear cells from a G1 piglet that had an abnormal nose phenotype. We reasoned that, if the phenotypic abnormality of the G1 clone was not present in the G2 and third-generation (G3) clones, or was absent in the G2 clones but reappeared in the G3 clones, the phenotypic instability of the G1 clone could be attributed to faulty epigenetic reprogramming rather than to inherent/accidental genomic damage to the donor cells. Blastocyst rates, cell numbers in blastocyst, pregnancy rates, term placenta weight and ponderal index, and birth weight between G1 and G2 clones did not differ, but were significantly (P < 0.05) lower than control age- and sex-matched piglets. Next, we analyzed global methylation changes during development of the preimplantation embryos reconstructed by donor cells used for the production of G1 and G2 clones and could not find any significant differences in the methylation patterns between G1 and G2 clones. Indeed, we failed to detect the phenotypic abnormality in the G2 and G3 clones. Thus, the phenotypic abnormality of the G1 clone is likely to be due to epigenetic dysregulation. Additional observations then suggested that expression of the hTPO gene in the transgenic clones did not appear to be the cause of the phenotypic abnormality in the G1 clones and that the abnormality was acquired by only a few of the G1 clone's cells during its gestational development.

Abstract
This study investigated the effect of increased phylogenetic distance on the outcome of spermatogonial transplantation, with porcine donors and mice recipients. It was designed to develop a technique for detecting foreign donor cells in recipient animals. Porcine male germ cells were harvested from postnatal male testes and incubated with the lipophilic membrane dye PKH-26. For transplantation, approximately 10(6) PKH-26-labelled porcine male germ cells were injected into the efferent ducts of mouse testes. Animals were sacrificed at post-graft days 1, 10, 30, 45, 60 and 150 (n = 5 each). Serial frozen sections of explanted testes were prepared for detecting labelled cells. Transplanted porcine donor cells were easily detected in the recipient tubules for 8 weeks. After transplantation, we could detect both incorporation into the basement membrane and differentiation of grafted porcine donor cells by our double detection system, using PKH staining and slide PCR. However, our RT-PCR and apoptosis results revealed that most of the grafted porcine male donor cells could not differentiate past early-meiotic spermatocytes. We could induce partial differentiation of xenografted porcine donor cells in mouse testes, but not full induction of spermatogenesis. We have developed a very reliable technique for detecting foreign donor cells in recipient animals using a combination of PKH staining and slide PCR methods. Our results provide a valuable experimental model for applying and evaluating this technology in other species.

Abstract
Adhesion between Sertoli cells and germ cells is important for spermatogenesis. Cadherins are Ca(2+)-dependent transmembrane proteins that mediate cell-cell adhesion. The aim of this study was to compare the expression of P-cadherin in unilaterally cryptorchid and busulphan-treated rat testes using immunohistochemistry. The pattern of expression of P-cadherin in the seminiferous epithelium changed with the stage of the seminiferous epithelium. The membranes of round spermatids and membranes and cytoplasm of spermatocytes were strongly positive. Our experiments revealed that busulphan treatment (2 doses - 10 mg/kg of body weight - 21 days apart) and cryptorchism led to destructive changes in the structure of seminiferous tubules, together with the decrease in P-cadherin expression. The expression of P-cadherin disappeared in the spermatids segregated from the epithelium while segregated spermatocytes remained still positive for P-cadherin during the 3- to 11-day cryptorchid period. In busulphan-treated animals, the expression of P-cadherin was dependent on the presence or absence of the spermatocytes and spermatids in the tubules. Strong positivity for P-cadherin was observed in the spermatocytes that re-appeared in the regenerating seminiferous epithelium. We suggest that P-cadherin participates in the architecture of adherens junctions in testis, plays an important role in maintaining normal spermatogenesis and that cryptorchism and busulphan treatment lead to adherens junction disintegration.
