Intratesticular versus intraperitoneal Busulfan administration: a comparative study on spermatogenesis suppression in quails and chickens. Poult Sci 2024; 103:103890. [PMID: 38870613 PMCID: PMC11225892 DOI: 10.1016/j.psj.2024.103890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 05/15/2024] [Accepted: 05/20/2024] [Indexed: 06/15/2024] Open
Abstract
Generation of transgenic birds can be achieved by temporal suppression of endogenous spermatogenesis in males prior to primordial germ cell implantation. One of many established methods to induce male sterility is the intraperitoneal injection of busulfan, an alkylating agent. Nevertheless, the use of busulfan injections, which may also affect hematopoietic stem cells, carries the risk of potential lethality in animals. Given their safety and non-toxic nature, it has been demonstrated that intratesticular busulfan injections in mammals are less effective than intraperitoneal injections. This study aimed to compare, for the first time, the sterility and toxicity effects of intraperitoneal vs. intratesticular busulfan injections in quail and chickens. Our experimental design involved a previously established single intraperitoneal busulfan injection of 40 mg/kg of body weight (BW). In quail, busulfan was then administered intratesticularly at 3 different concentrations (6, 12, and 20 mg/kg BW), while in chickens, the working concentration was 20 mg/kg BW. We found that a single intraperitoneal busulfan injection of 40 mg/kg of BW resulted in 100% mortality in the treated roosters. In quails, however, this concentration only caused a temporary suppression of fertility for a 15-d period. Moreover, we found that a higher dose of intratesticular injection of busulfan is required to suppress spermatogenesis in quail (20 mg/kg BW) compared to mammals (4 mg/kg BW). Following these findings, we further confirmed that intratesticular injection of 20 mg/kg BW busulfan into roosters did not affect their overall viability. However, it induced a temporary state of male sterility, consistent with the effects observed with intraperitoneal injections. Hence, our data demonstrate that quail and chicken respond differently to busulfan administration. Furthermore, the present study provides evidence that direct injection into the rooster testes causes less physiological stress than intraperitoneal injection.

Intratesticular versus intraperitoneal injection of Busulfan for the induction of azoospermia in a rat model. BMC Pharmacol Toxicol 2022; 23:50. [PMID: 35831882 PMCID: PMC9281107 DOI: 10.1186/s40360-022-00587-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 06/30/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Administration of antineoplastic drugs may cause azoospermia driving to subfertility. Production of animal azoospermia models is essential for evaluating new treatment methods before therapeutic interventions in human setup. This study aimed to investigate the toxic effects of Busulfan (an anticancer drug) on some vital organs and describe the best method and appropriate dose of Busulfan to induce an animal azoospermia model. METHODS Rats were randomly assigned into four groups, treatment groups received 10 mg/kg, 40 mg/kg Busulfan intraperitoneally (IP), 5 mg/kg Busulfan intratesticular (IT), and control group. Blood, bone marrow, liver, renal, and testes samples were collected for histological (H&E staining), biochemical (serum levels of ALT, AST, ALP, creatinine, and urea), and hematological analyses. RESULTS Results revealed severe anemia and leukopenia in rats that received Busulfan via IP. By contrast, injection of 5 mg/kg Busulfan via IT did not cause anemia except with a mild decrease in RBC count. Non-significant differences in the M/E ratio were observed in all groups. The administration of 40 mg/kg of Busulfan led to evacuation and destruction in the spermatogenesis process with thin-walled seminiferous epithelium in most tubules, but in rats treated with 10 mg/kg of Busulfan, the normal spermatogenesis process was notified. IT injection of Busulfan contributed to the complete degradation of spermatogenesis in which all spermatogenic cells degenerated. In the renal tissue, hyperemia, extensive tubular necrosis degeneration, and hyaline casts were found after IP injection of Busulfan. In hepatic tissue, focal hemorrhagic, chronic cholangitis, and hepatocyte degeneration, and swelling were noticed. Biochemical analysis revealed apparent Busulfan toxicity of both hepatic and renal tissues in IP Busulfan-treated rats. CONCLUSIONS In summary, we found that the intratesticular injection of low doses of Busulfan (5 mg/kg) is a relatively non-invasive and safe method for producing the rat azoospermia model causing the least toxicity on vital organs.

Abstract
BACKGROUND Although the prognosis of childhood cancer survivors has increased dramatically during recent years, chemotherapy and radiation treatments for cancer and other conditions may lead to permanent infertility in prepubertal boys. Recent developments have shown that spermatogonial stem cell (SSC) transplantation may be a hope for restoring fertility in adult survivors of childhood cancers. For this reason, several centres around the world are collecting and cryopreserving testicular tissue or cells anticipating that, in the near future, some patients will return for SSC transplantation. This review summarizes the current knowledge and utility of SSC transplantation techniques. OBJECTIVE AND RATIONALE The aim of this narrative review is to provide an overview of the currently used experimental injection techniques for SSC transplantation in animal and human testes. This is crucial in understanding and determining the role of the different techniques necessary for successful transplantation. SEARCH METHODS A comprehensive review of peer-reviewed publications on this topic was performed using the PubMed and Google Scholar databases. The search was limited to English language work and studies between 1994 (from the first study on SSC transplantation) and April 2019. Key search terms included mouse, rat, boar, ram, dog, sheep, goat, cattle, monkey, human, cadaver, testes, SSC transplantation, injection and technique. OUTCOMES This review provides an extensive clinical overview of the current research in the field of human SSC transplantation. Rete testis injection with ultrasonography guidance currently seems the most promising injection technique thus far; however, the ability to draw clear conclusions is limited due to long ischemia time of cadaver testis, the relatively decreased volume of the testis, the diminishing size of seminiferous tubules, a lack of intratesticular pressure and leakage into the interstitium during the injection on human cadaver testis. Current evidence does not support improved outcomes from multiple infusions through the rete testes. Overall, further optimization is required to increase the efficiency and safety of the infusion method. WIDER IMPLICATIONS Identifying a favourable injection method for SSC transplantation will provide insight into the mechanisms of successful assisted human reproduction. Future research could focus on reducing leakage and establishing the optimal infusion cell concentrations and pressure.

Abstract
To clarify the effect of busulfan on the depletion of spermatogonial stem cells (SSCs) from shal rams testis, in the first experiment, lambs were treated by intraperitoneal injection with 4 mg/kg busulfan. In the second experiment, different concentrations of busulfan (1, 2 and 4 mg/kg) were injected directly into both sides of the left testis. The testes of 8 lambs were collected by standard castration procedure for histological analysis five weeks after the treatments and the left testis of remaining lambs were collected after eight weeks and a two-time enzymatic digestion process was used to isolate SSCs. The results showed that all rams that had received intraperitoneal injections of busulfan died. But by testicular injecting of same dose of the drug, 40% of the animals died. The testicular injection of rams with 1, 2 and 4 mg/kg of busulfan resulted in a dose dependent decrease in testis size and also spermatocytes population after 5 weeks of treatments. From the results of colony formation 8 weeks after treatment with busulfan, it can be concluded that only in 1 and 2 mg/kg of busulfan, recovery of endogenous germ cells was performed. In conclusion, the results demonstrated that intra-testicular injections of busulfan (2 mg/kg) reduced spermatocytes population in ram testis within 5 weeks of treatments, and this effect was reversible within 8 weeks of injection. However, it was not recommended to inject 4 mg/kg busulfan into the peritoneal cavity or testis of lambs based on its side effects.

Abstract
The object of this study was to investigate if testis germ cell transplantation (TGCT) into a heterologous recipient would result in donor-origin spermatogenesis in the dromedary camel. First, we investigated a workable protocol for TGCT in camels, including donor cell isolation, enrichment by density gradient centrifugation (Percoll and Bovicoll), rete testis injection and microsatellite detection of donor and recipient genotypes. Second, the effects of three doses of Dolichos biflorus agglutinin (DBA), a glycoprotein that specifically binds to gonocytes or Type A spermatogonia, on testis germ cell depletion were investigated by direct injection into the rete testis of a male camel. Seven recipients were prepared with DBA treatment, two males were castrated at 4 weeks for depletion assessment and the remaining five received donor cells 4-6 weeks after treatment. On average, ~17 million cells were isolated per gram of testis tissue, with 19.5±1.9% DBA-positive (DBA+) cells. Percoll centrifugation yielded a 1.5-fold increase in DBA+ cells while Bovicoll centrifugation produced a 2.5-fold increase from the input cells of 18.6±2.1% DBA+ cells. Semen was collected from the recipients 13-20 weeks after transfer and the presence of donor DNA in the samples was determined using microsatellite markers. In two of the five recipients, all semen samples were shown to be positive for donor-derived cells. These results demonstrate for the first time that: (1) heterologous testicular germ cell transplantation in camels is feasible and the recipients are able to produce spermatozoa of donor origin and (2) DBA can be used effectively to deplete endogenous stem cells.

Abstract
Research on in vitro culture and gene editing of domestic spermatogonial stem cells (SSCs) is of considerable interest but remains a challenging issue in animal science. In recent years, some progress on the isolation, purification, and genetic manipulation of porcine SSCs has been reported. Here, we summarize the characteristics of porcine SSCs as well current advances in their in vitro culture, potential usage, and genetic manipulation. Furthermore, we discuss the current application of gene editing in pig cloning technology. Collectively, this commentary aims to summarize the progress made and obstacles encountered in porcine SSC research to better serve animal husbandry, improve livestock fecundity, and enhance potential clinical use.

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
The preparation of spermatogonial stem cell (SSC) transplant recipients laid the technical foundation for SSC transplant technology and the understanding of spermatogenesis mechanisms. Busulfan is commonly used to prepare recipients for mouse SSC transplantation; however, its safety and efficiency have been questioned. This review summarizes the relationship between SSCs and Sertoli cells (SCs), and the mechanism of busulfan toxicity against sperm cells. We concluded that the proliferation, differentiation, and apoptosis of SSCs are regulated by SCs. The endogenous spermatogenic cells are depleted by busulfan treatment via alkylation of DNA, destruction of vimentin filament distribution, disruption of SSC differentiation, promotion of SSC dormancy, and generation of oxidative stress. However, the mechanisms require further exploration. The recent establishment of a model in vitro culture system has provided a good technical foundation to further explore these mechanisms, which will help us to find more efficient methods of recipient preparation and optimal transplantation times.
