Objective: This article reports the second live birth in China after frozen-thawed ovarian tissue transplantation to prevent iatrogenic premature ovarian insufficiency (POI).
Method: A patient with aplastic anemia received ovarian tissue cryopreservation before hematopoietic stem cell transplantation, and four ovarian cortex strips were thawed and transplanted into her peritoneal pocket 18 months later.
Results: Pregnancy occurred spontaneously 5 years after grafting, and a healthy girl was born at 39 weeks of gestation. Until now, the child has developed normally without any major diseases.
Conclusion: Ovarian tissue cryopreservation and transplantation (OTCT) can be assessed as a successful method especially to prevent iatrogenic POI. In our cryobank for OTCT, which is the first official one in China, intensive research to improve this method has been performed, and we propose after our success for the second pregnancy in China to include this method in the official guidelines for prevention and treatment of (especially iatrogenic) POI.

Ovarian cancer (OC) is characterized by high mortality rates due to late diagnosis, recurrence, and metastasis. Here, we show that extracellular signaling molecules secreted by adipose-derived mesenchymal stem cells (ASCs) and OC cells-either in the conditioned medium (CM) or within small extracellular vesicles (sEVs)-modulate cellular responses and drive OC progression. ASC-derived sEVs and CM secretome promoted OC cell colony formation, invasion, and migration while upregulating tumor-associated signaling pathways, including TGFβ/Smad, p38MAPK/ERK1/2, Wnt/β-catenin, and MMP-9.

Patient-derived xenograft (PDX) models are powerful tools in cancer research, offering an accurate platform for evaluating cancer treatment efficacy and predicting responsiveness. However, these models necessitate surgical techniques for tumor tissue transplantation and face challenges with non-uniform tumor growth among animals. To address these issues, we attempted to develop a new PDX modeling method using high-grade serous ovarian cancer (HGSC), a fatal disease with a 5-year survival rate of 29%, which requires personalized research due to its morphological, genetic, and molecular heterogeneities.

Background: The adaptive immune system consists of T and B lymphocytes, with some B lymphocytes further differentiating into plasma cells that secrete antibodies and make up the humoral immune system. Extramedullary plasmacytoma, mucosa-associated lymphoid tissue (MALT) lymphoma, and plasmablastic lymphoma are all plasma cell-rich lymphoid neoplasms that rarely present in the female genital tract. To date, few case reports of these malignancies arising within the uterine cervix exist.

Primary small cell carcinoma of the ovary is an extremely rare and highly malignant ovarian malignancy. The tissue origin of this type of cancer is still unclear, and it is characterized by rapid progression and a discouraging prognosis. The clinical presentation of small cell carcinoma of the ovary lacks specificity, and there are currently no effective treatment options available.

Introduction: Women who carry the breast cancer gene () pathogenic variants have a higher lifetime risk of developing ovarian cancer than the general population (, 44%; , 17%). There is currently no reliable method for the early detection of ovarian cancer, and the prognosis of advanced ovarian cancer is poor. Therefore, risk-reducing salpingo-oophorectomy (RRSO) is recommended for patients with breast cancer who carry pathogenic variants.
