Human Villous Trophoblasts

Description

Human villous trophoblasts (HVT) are primary cells isolated from human placental villi, typically obtained from healthy pregnancies. These cells represent the progenitor population of the placental villi and exhibit distinct morphological features, including mononuclear cytotrophoblasts that fuse to form multinucleated syncytiotrophoblasts. HVT cells are cryopreserved at earliest passage and are not recommended for long-term expansion due to their limited proliferative capacity. Functionally, HVT mediate nutrient exchange, secrete pregnancy-sustaining hormones such as human chorionic gonadotropin (hCG) and placental lactogen, and express chemokine receptors CXCR4 and CCR5. These characteristics position HVT as a critical model for studying placental development and gestational pathologies.

Application

• Human villous trophoblasts offer versatile applications in scientific research. They serve as an ideal cellular platform for investigating cell differentiation and organogenesis while also support the development of disease models for high-throughput and high-content screening. These cells are invaluable for researchers studying the molecular mechanisms underlying human placental development and pathology, helping to illuminate key events in placental morphogenesis and trophoblast regulation within the villous environment.
