Alterations in cfDNA concentration, fragmentation patterns, and molecular characteristics under physiological and pathological conditions, including pregnancy-related disorders, have established its value as a minimally invasive biomarker for early disease detection and clinical monitoring. Due to the availability of non- or minimally-invasive and scalable detection platforms with high sensitivity and specificity, cfDNA has emerged as a powerful tool in maternal-fetal medicine. This review provides a comprehensive overview of recent advances in cfDNA research, with an emphasis on its applications in pregnancy-related disorders. We elucidate the underlying biological mechanisms, current diagnostic and prognostic uses, analytical technologies, and the key challenges and future directions for clinical translation.<\/jats:p>","DOI":"10.3389\/fcell.2025.1600532","type":"journal-article","created":{"date-parts":[[2025,8,5]],"date-time":"2025-08-05T05:24:51Z","timestamp":1754371491000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Advances in cfDNA research for pregnancy-related diseases"],"prefix":"10.3389","volume":"13","author":[{"given":"Yimei","family":"Meng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoshan","family":"Yue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxiang","family":"Mo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,8,5]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"S232","DOI":"10.2337\/dc22-S015","article-title":"15.
