All three studies showed reduced embryonic absorption, promoting pregnancy maintenance. The EVs were extracted from trophoblasts, decidual stromal cells, or bone marrow stem cells, and administered intravenously, primarily, in dose of 100 or 200\u00a0\u00b5g. All EVs have immunomodulatory relevance in pregnancy, modifying the lymphocyte and cytokine patterns, and contributing to angiogenesis and trophoblast growth.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We conclude that EVs represent a potential area for the development of future therapies for pregnancies with RSA, and new studies are necessary to confirm these findings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/aji.70197","type":"journal-article","created":{"date-parts":[[2025,12,17]],"date-time":"2025-12-17T13:30:46Z","timestamp":1765978246000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Extracellular Vesicles for the Maintenance of Pregnancies in Situations of Recurrent Spontaneous Abortion: Scoping Review"],"prefix":"10.1111","volume":"94","author":[{"given":"Marcelo","family":"Garrido","sequence":"first","affiliation":[{"name":"Medicine Course University of Western S\u00e3o Paulo (UNOESTE)  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco Monico","family":"Moreira","sequence":"additional","affiliation":[{"name":"Medicine Course University of Western S\u00e3o Paulo (UNOESTE)  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis Antonio Gilberti","family":"Panucci","sequence":"additional","affiliation":[{"name":"Medicine Course University of Western S\u00e3o Paulo (UNOESTE)  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8690-5294","authenticated-orcid":false,"given":"Graziela Garrido","family":"Mori","sequence":"additional","affiliation":[{"name":"Medicine Course University of Western S\u00e3o Paulo (UNOESTE)  S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,17]]},"reference":[{"issue":"1","key":"e_1_2_9_2_1","article-title":"Recurrent Miscarriage: Diagnosis, Investigation and Initial Management","volume":"39","author":"Rauber F.","year":"2018","journal-title":"Acta Medica\u2014Ligas Acad"},{"issue":"1","key":"e_1_2_9_3_1","first-page":"63","article-title":"Women's Mental Health in the Face of Spontaneous Abortion: An Integrative Review","volume":"12","author":"Azevedo S.
