Hormone replacement therapy (HRT), the standard of care for POI, delivers only a subset of ovarian hormones and fails to mimic the monthly cyclicity and daily pulsatility characteristic of healthy ovarian tissue in reproductive-aged individuals whose ovarian tissue contains thousands of ovarian follicles. Ovarian tissue allografts have the potential to serve as an alternative, cell-based HRT, capable of producing the full panel of ovarian hormones at physiologically relevant doses and intervals. However, the risks associated with systemic immune suppression (IS) required to prevent allograft rejection outweigh the potential benefits of comprehensive and dynamic hormone therapy. This work investigates whether the age of ovarian tissue donor animals affects the function of, and immune response to, subcutaneous ovarian grafts. We performed syngeneic and semi-allogeneic ovarian transplants using tissue from mice aged 6\u20138 (D7) or 20\u201322 (D21) days and evaluated ovarian endocrine function and immune response in a mouse model of POI. Our results revealed that tissue derived from D7 donors, containing an ample and homogeneous primordial follicle reserve, was more effective in fully restoring hypothalamic\u2013pituitary\u2013ovarian feedback. In contrast, tissue derived from D21 donors elicited anti-donor antibodies with higher avidity compared to tissue from younger donors, suggesting that greater immunogenicity may be a trade-off of using mature donors. This work contributes to our understanding of the criteria donor tissue must meet to effectively function as a cell-based HRT and explores the importance of donor age as a factor in ovarian allograft rejection.<\/jats:p>","DOI":"10.3390\/ijms25063431","type":"journal-article","created":{"date-parts":[[2024,3,19]],"date-time":"2024-03-19T04:36:31Z","timestamp":1710822991000},"page":"3431","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Donor Age on Endocrine Function of and Immune Response to Ovarian Grafts"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4761-4179","authenticated-orcid":false,"given":"Monica A.","family":"Wall","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayara","family":"Garcia de Mattos Barbosa","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalie","family":"Hanby","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle M.","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"School of Medicine, Yale University, New Haven, CT 06510, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret","family":"Brunette","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2156-3561","authenticated-orcid":false,"given":"Despina I.","family":"Pavlidis","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Arrowsmith","sequence":"additional","affiliation":[{"name":"Department of Pathology, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ansen Q.","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Department of Biomedical Engineering, Northwestern University, Evanston, IL 60208, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marilia","family":"Cascalho","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Department of Surgery, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0159-6419","authenticated-orcid":false,"given":"Ariella","family":"Shikanov","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI 48109, USA"},{"name":"Department of Obstetrics and Gynecology, Cellular & Molecular Biology Program, Department of Macromolecular Science & Engineering, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"787","DOI":"10.1097\/GRF.0b013e3181f97a55","article-title":"Cryopreservation and transplantation of ovarian tissue","volume":"53","author":"Donnez","year":"2010","journal-title":"Clin.
