Abstract:
Ovarian tissue transplantation (OTT) is the only option for preserving fertility in prepubertal girls and young women who require immediate cancer treatment. Due to ethical constraints and the limited number of clinical cases, human OTT research is challenging. Mouse OTT models serve as valuable preclinical models. This article aims to review the current status of mouse OTT models, including xenotransplantation from humans. We conducted a systematic analysis of original research articles and reviews of mouse OTT models published in PubMed and the China National Knowledge Infrastructure (CNKI). The construction methods included different mouse strains (C57/BL6, Institute of Cancer Research, Naval Medical Research Institute, genetically engineered, and immunodeficient mice), transplantation sites (subcutaneous tissue, sub-renal capsule, back muscle, peritoneum, and ovarian bursa), and transplantation types (xenotransplantation, allogeneic, and autologous transplantation). The evaluation metrics included histological analysis, assessment of neovascularization density, measurement of granulosa cell proliferation activity, and hormonal and estrous cycle monitoring. The choice of metrics should be selected according to the stage after transplantation. To advance the clinical application, mouse OTT models could be improved by developing standardized evaluation criteria and simplified, rapid, noninvasive detection methods to enhance consistency and comparability of research outcomes. Key areas for further research include addressing safety concerns (eg, risk of tumor cell reimplantation), optimizing efficacy evaluations (eg, follicle quality and endocrine function recovery), and improving cost-effectiveness through analysis of mouse strains and transplantation protocols. This review provides valuable insights for future research and clinical applications.
Insights
Mouse ovarian tissue transplantation (OTT) models are crucial for fertility preservation research, especially for young cancer patients. This review analyzes current models and suggests improvements for clinical application.
Area of Science:
- Reproductive Biology
- Oncology
- Transplantation Science
Background:
- Ovarian tissue transplantation (OTT) is the sole fertility preservation method for prepubertal girls and young women needing immediate cancer treatment.
- Ethical and clinical limitations hinder human OTT research, necessitating reliable preclinical models.
- Mouse OTT models, including human xenotransplantation, are vital for advancing fertility preservation strategies.
Purpose of the Study:
- To systematically review the current status of mouse ovarian tissue transplantation (OTT) models.
- To analyze various construction methods, transplantation sites, and types used in mouse OTT models.
- To identify key areas for improving mouse OTT models for enhanced clinical application.
Main Methods:
- Systematic analysis of original research articles and reviews from PubMed and CNKI databases.
- Categorization of mouse OTT models based on mouse strains, transplantation sites, and transplantation types (xenogeneic, allogeneic, autologous).
- Evaluation of common metrics including histological analysis, neovascularization, granulosa cell proliferation, and hormonal monitoring.
Main Results:
- Diverse mouse strains, transplantation sites (subcutaneous, sub-renal capsule, etc.), and transplantation types are employed.
- Histological analysis, neovascularization assessment, proliferation assays, and hormonal monitoring are key evaluation metrics.
- Standardization of criteria and development of noninvasive detection methods are needed for improved consistency and comparability.
Conclusions:
- Mouse OTT models offer valuable insights for human fertility preservation but require refinement.
- Future research should focus on standardized evaluation, safety (tumor cell risk), efficacy (follicle quality, endocrine function), and cost-effectiveness.
- Optimizing mouse strains and transplantation protocols is crucial for advancing clinical OTT applications.
