GFP/Luc Reporter Cell Line - Ishikawa

Ishikawa is a human endometrial adenocarcinoma cell line originally established from a well-differentiated endometrial carcinoma of the uterus. It is commonly used as an in vitro model for studying endometrial cancer biology and steroid hormone signaling, particularly due to its responsiveness to estrogen and progesterone stimulation. The GFP/Luc Reporter Cell Line - Ishikawa is generated through stable transfection to co-express green fluorescent protein (GFP) and firefly luciferase (Luc) reporter genes in Ishikawa cells. This dual-reporter system enables both fluorescence-based visualization and quantitative bioluminescence detection. The engineered cells maintain the parental biological characteristics, including hormone sensitivity and growth properties, while providing a stable and sensitive platform for real-time monitoring of cellular activity.

The Ishikawa-GFP/Luc reporter cell line is widely used in endometrial cancer research and preclinical studies involving hormone-dependent tumor progression. In vivo, luciferase activity allows non-invasive longitudinal tracking of tumor growth and response to therapy in xenograft models, while GFP expression supports direct visualization of cell distribution and morphology in vitro and in harvested tissues. This model is particularly useful for evaluating the effects of endocrine therapies, including selective estrogen receptor modulators and progesterone-based treatments, under controlled experimental conditions. It is also applied in drug screening assays to assess anti-proliferative effects and treatment efficacy over time. In addition, the dual-reporter system facilitates studies on gene regulation, metastatic behavior, and tumor microenvironment interactions. Overall, the Ishikawa-GFP/Luc cell line provides a robust and reproducible tool for investigating endometrial cancer mechanisms and for supporting translational research in hormone-related gynecologic oncology.
