Germ cell tumours of the liver are rare neoplasms, with fewer than 20 cases reported in the literature following presentation as teratomas, choriocarcinomas or yolk sac tumours. We report a 52-year-old patient who complained of upper abdominal pain and anorexia. Ultrasonography and computed tomography of the abdomen revealed a large hepatic mass. Among the laboratory values we found elevated levels of alpha-fetoprotein and beta-chorionic gonadotropin. Repeated biopsies via CT scan, laparoscopy and laparotomy disclosed a poorly differentiated adenocarcinoma. Subsequently liver function deteriorated and, on the basis of clinical data highly suggestive of a malignant germ cell tumour, a modified chemotherapeutic protocol (PEI) was initiated. The elevated levels of alpha-fetoprotein and beta-chorionic gonadotropin declined rapidly, but the patient died 10 days later of liver dysfunction and bronchopneumonia. Subsequent autopsy confirmed the initial clinical diagnosis of a multilocular extragonadal malignant germ cell tumour of the liver with components of choriocarcinoma and embryonal carcinoma.

Sertoli cells (SCs), as the somatic cells in the testis of male mammals, play a crucial role in the close association with germ cells. The blood-testicular barrier (BTB), established by their tight junctions, provides immune protection to germ cells, leading to their characterization as "sentinel" cells. Moreover, the physiological process of testicular development and spermatogenesis in male animals is intricately tied to the secretory activities of SCs.

Ovarian sex cord-stromal tumors (SCST) are a rare subset of ovarian neoplasms originating from supportive tissues surrounding oocytes. Despite their rarity, prompt diagnosis and management are crucial due to their potential for diverse clinical presentations and the need to optimize patient outcomes. A 25-year-old female patient was initially diagnosed with pyelonephritis but later discovered to have a large right adnexal mass suspected to be a tubo-ovarian abscess.

Male factor accounts for 30-50% of infertility cases and may occur due to congenital anomalies or acquired disorders. In such infertility cases where a limited number of mature sperm is produced, a solution is offered to patients with ART applications; however, these methods are inadequate in patients with germ cell aplasia due to damaged microenvironment. Since monolayer cell culture and static culture conditions do not provide the physical conditions of the 3D microenvironment, they have a limited effect on ensuring the execution of in vitro spermatogenesis properly.

In mammalian oocytes, large-scale chromatin organization regulates transcription, nuclear architecture, and maintenance of chromosome stability in preparation for meiosis onset. Pre-ovulatory oocytes with distinct chromatin configurations exhibit profound differences in metabolic and transcriptional profiles that ultimately determine meiotic competence and developmental potential. Here, we developed a deep learning pipeline for the non-invasive prediction of chromatin structure and developmental potential in live mouse oocytes.

Akkermansia muciniphila is a promising target for managing obesity and type 2 diabetes (T2D), but human studies are limited. We conducted a 12-week randomized, double-blind, placebo-controlled trial involving 58 participants with overweight or obese T2D, who received A. muciniphila (AKK-WST01) or placebo, along with routine lifestyle guidance.
