Morimoto H, Kanatsu-Shinohara M, Shinohara T. WIN18,446 enhances spermatogonial stem cell homing and fertility after germ cell transplantation by increasing blood-testis barrier permeability. J Reprod Dev 2023; 69:347-355.

Abstract
Spermatogonial stem cells (SSCs) possess a unique ability to recolonize the seminiferous tubules. Upon microinjection into the adluminal compartment of the seminiferous tubules, SSCs transmigrate through the blood-testis barrier (BTB) to the basal compartment of the tubule and reinitiate spermatogenesis. It was recently discovered that inhibiting retinoic acid signaling with WIN18,446 enhances SSC colonization by transiently suppressing spermatogonia differentiation, thereby promoting fertility restoration. In this study, we report that WIN18,446 increases SSC colonization by disrupting the BTB. WIN18,446 altered the expression patterns of tight junction proteins (TJPs) and disrupted the BTB in busulfan-treated mice. WIN18,446 upregulated the expression of FGF2, one of the self-renewal factors for SSCs. While WIN18,446 enhanced SSC colonization in busulfan-treated wild-type mice, it did not increase colonization levels in busulfan-treated Cldn11-deficient mice, which lack the BTB, indicating that the enhancement of SSC colonization in wild-type testes depended on the loss of the BTB. Serial transplantation analysis revealed impaired self-renewal caused by WIN18,446, indicating that WIN18,446-mediated inhibition of retinoic acid signaling impaired SSC self-renewal. Strikingly, WIN18,446 administration resulted in the death of 45% of busulfan-treated recipient mice. These findings suggest that TJP modulation is the primary mechanism behind enhanced SSC homing by WIN18,446 and raise concerns regarding the use of WIN18,446 for human SSC transplantation.

Abstract
In vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are 2 major assisted reproductive techniques (ARTs) used widely to treat infertility. Recently, spermatogonial transplantation emerged as a new ART to restore fertility to young patients with cancer after cancer therapy. To examine the influence of germ cell manipulation on behavior of offspring, we produced F1 offspring by a combination of two ARTs, spermatogonial transplantation and ICSI. When these animals were compared with F1 offspring produced by ICSI using fresh wild-type sperm, not only spermatogonial transplantation-ICSI mice but also ICSI-only control mice exhibited behavioral abnormalities, which persisted in the F2 generation. Furthermore, although these F1 offspring appeared normal, F2 offspring produced by IVF using F1 sperm and wild-type oocytes showed various types of congenital abnormalities, including anophthalmia, hydrocephalus, and missing limbs. Therefore, ARTs can induce morphological and functional defects in mice, some of which become evident only after germline transmission.

Abstract
Background: Extensive research on the blood-testis barrier has been undertaken in recent years. However, no systematic bibliometric study has been conducted on this subject. Our research aimed to identify the hotspots and frontiers of blood-testis barrier research and to serve as a guide for future scientific research and decision-making in the field.Methods: Studies on the blood-testis barrier were found in the Web of Science Core Collection. VOSviewer, CiteSpace, and Microsoft Excel were used to conduct the bibliometric and visual analyses.Results: We found 942 blood-testis barrier studies published in English between 1992 and 2022. The number of annual publications and citations increased significantly between 2011 and 2022, notably in the United States. China and the United States, the US Population Council, Endocrinology, and Cheng C. Yan were the most productive countries, institution, journal, and author, respectively. The study keywords indicated that blood-testis barrier research involves a variety of compositional features (tight junctions, cytoskeleton, adherens junctions), cell types (Sertoli cells, germ cells, Leydig cells, stem cells), reproductive toxicity (cadmium, nanoparticles, bisphenol-a), and relevant mechanisms (spermatogenesis, apoptosis, oxidative stress, dynamics, inflammation, immune privilege).Conclusion: The composition and molecular processes of the blood-testis barrier as well as the blood-testis barrier in male infertility patients are the primary research hotspots in this field. In addition, future research will likely focus on treatment and the development of novel medications that target signal pathways in oxidative stress and apoptosis to preserve the blood-testis barrier. Further studies must extend to clinical diagnosis and therapy.

Abstract
Germline stem cells (GSCs) are germ cells with the capacities of self-renewal and differentiation into functional gametes, and are able to migrate to their niche and reconstitute the fertility of recipients after transplantation. Therefore, GSCs transplantation is a promising technique for fertility recovery in the clinic, protection of rare animals and livestock breeding. Though this novel technique faces tremendous challenges, numerous achievements have been made after several decades' endeavor. This review summarizes the current knowledge of GSCs transplantation and its utilization in mammals, and discusses the application prospect in reproductive medicine and animal science.

Abstract
Gametogenesis requires close interactions between germ cells and somatic cells. Derivation of sperm from spermatogonial stem cells (SSCs) is hampered by the inefficiency of spermatogonial transplantation technique in many animal species because it requires a large number of SSCs and depletion of endogenous spermatogenesis. Here we used mouse testis primordia and organoids to induce spermatogenesis from SSCs. We microinjected mouse SSCs into embryonic gonads or reaggregated neonatal testis organoids, which were transplanted under the tunica albuginea of mature testes. As few as 1 × 104 donor cells colonized both types of transplants and produced sperm. Moreover, rat embryonic gonads supported xenogeneic spermatogenesis from mouse SSCs when transplanted in testes of immunodeficient mice. Offspring with normal genomic imprinting patterns were born after microinsemination. These results demonstrate remarkable flexibility of the germ cell-somatic cell interaction and raise new strategies of SSC manipulation for animal transgenesis and analysis of male infertility. SSCs can be injected into embryonic gonads or reaggregated neonatal testes Spermatogenesis occurs in the gonads or reaggregated testes after transplantation Offspring are born from SSC-derived sperm using microinsemination Offspring show normal DNA methylation in imprinted genes

Abstract
Spermatogonial stem cells (SSCs) undergo continuous self-renewal division in response to self-renewal factors. The present study identified ephrin type-A receptor 2 (EPHA2) on mouse SSCs and showed that supplementation of glial cell-derived neurotrophic factor (GDNF) and fibroblast growth factor 2 (FGF2), which are both SSC self-renewal factors, induced EPHA2 expression in cultured SSCs. Spermatogonial transplantation combined with magnetic-activated cell sorting or fluorescence-activated cell sorting also revealed that EPHA2 was expressed in SSCs. Additionally, ret proto-oncogene (RET) phosphorylation levels decreased following the knockdown (KD) of Epha2 expression via short hairpin ribonucleic acid (RNA). Although the present immunoprecipitation experiments did not reveal an association between RET with EPHA2, RET interacted with FGFR2. The Epha2 KD decreased the proliferation of cultured SSCs and inhibited the binding of cultured SSCs to laminin-coated plates. The Epha2 KD also significantly reduced the colonization of testis cells by spermatogonial transplantation. EPHA2 was also expressed in human GDNF family receptor alpha 1-positive spermatogonia. The present results indicate that SSCs express EPHA2 and suggest that it is a critical modifier of self-renewal signals in SSCs.

Intratesticular Human Adipose-Derived Stem Cell (hADSC) Transplantation Decreased Oxidative Stress in Testicular Torsion Model of Wistar Rat. Res Rep Urol 2021; 13:1-8. [PMID: 33442548 PMCID: PMC7797314 DOI: 10.2147/rru.s283861] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Accepted: 11/16/2020] [Indexed: 12/22/2022] Open
Abstract
Introduction Testicular torsion is a sudden rotation of the testis towards its axis, which causes the twisting of the spermatic cord. Post-detorsion reperfusion will cause inflammation and trigger oxidative stress, which generates reactive oxygen species (ROS). Malondialdehyde (MDA) is an organic compound formed from ROS frequently used as an oxidative stress biomarker during ischemia and ischemia-reperfusion injury. In some organs, stem cell administration on the damaged organ is essential in preventing cellular damage and death. This study aimed to learn about the effect of hADSC administration on an ischemia-reperfusion injury. Material and Methods A total of 22 Wistar rats divided into 5 groups, two groups each consist of 5 male Wistar rats with testicular torsion model without hADSC therapy (group I), while 2 other groups consist of 5 rats with testicular torsion model were given 1.0×106 cells intratesticular hADSC injection 30 minutes after testicular detorsion (group II). Both groups were euthanized at 1 and 4 weeks of observation. The last group consists of 2 rats without any treatment or model (negative control group). Following euthanasia, testicular tissue was harvested for MDA expression measurement using ELISA and histopathological examination. Statistical analysis using an one way ANOVA was done with SPSS version 21.0. Results The result of MDA examination using the ELISA method has shown a concentration difference between group I (control) and group II (hADSC treatment). Testicular MDA concentration in the treatment group was significantly lower on the 1st and 4th week of observation (p2=0.000, p4=0.016). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.972). On histopathological examination, Johnsen score in the treatment group was significantly higher on the 4th week of observation (p=0.044). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.195). Conclusion Intratesticular hADSC administration can inhibit ROS formation due to ischemia-reperfusion injury in testicular tissue after testicular detorsion in Wistar rats.
