However, the mechanism underlying this propensity remains unknown. A previous study found that human omental adipose-derived mesenchymal stem cells are potentially involved in ovarian cancer growth and metastasis, but the results were inconsistent and even contradictory. In addition, the underlying mechanisms of visceral adipose metastasis remain poorly understood. Here, our goal is to clarify the role and mechanism of human omental adipose-derived mesenchymal stem cells (HO-ADSCs) in EOC cancer growth and metastasis. We first found that human omental tissue conditioned medium (HO-CM) enhances EOC cell function. Subsequent coculture studies indicated that HO-ADSCs increase the growth, migratory and invasive capabilities of ovarian cancer cells. Then, we demonstrated that exosomes secreted by HO-ADSCs (HO-ADSC exosomes) enhanced ovarian cancer cell function, and further mechanistic studies showed that the FOXM1, Cyclin F, KIF20A, and MAPK signaling pathways were involved in this process. In addition, subcutaneous tumorigenesis and peritoneal metastatic xenograft experiments provided evidence that HO-ADSC exosomes promote ovarian cancer growth and metastasis in vivo. Finally, our clinical studies provided evidence that ascites from ovarian cancer patients enhance EOC cell line proliferation, migration, and invasion in vitro. The present study indicated that HO-ADSC exosomes are secreted into ascites and exert a tumor-promoting effect on EOC growth and metastasis, providing a new perspective and method to develop future novel therapeutic strategies for the treatment of ovarian cancer.<\/jats:p>","DOI":"10.3390\/cells11213392","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T20:37:58Z","timestamp":1666903078000},"page":"3392","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Exosomes from Human Omental Adipose-Derived Mesenchymal Stem Cells Secreted into Ascites Promote Peritoneal Metastasis of Epithelial Ovarian Cancer"],"prefix":"10.3390","volume":"11","author":[{"given":"Qingxi","family":"Qu","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linghong","family":"Liu","sequence":"additional","affiliation":[{"name":"Research Center of Stem Cell and Regenerative Medicine, Shandong University, Jinan 250012, China"},{"name":"Laboratory of Cryomedicine, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuqian","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaodu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Qilu Hospital of Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1240","DOI":"10.1016\/S0140-6736(18)32552-2","article-title":"Epithelial ovarian cancer","volume":"393","author":"Lheureux","year":"2019","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1498","DOI":"10.1038\/nm.2492","article-title":"Adipocytes promote ovarian cancer metastasis and provide energy for rapid tumor growth","volume":"17","author":"Nieman","year":"2011","journal-title":"Nat.
