Immortalized Human Bronchial Epithelial Cell Line

Posted Jul 22 2010 5:00pm

Description of Invention:
Normal cells can be cultured in vitro for a limited period of time before they exhibit a "crisis" or senescence, wherein they display abnormal cell morphology and significant reduction or cessation of cell proliferation. Investigators at the National Cancer Institute developed immortalized cell line by isolating bronchial epithelial cells from non-cancerous individuals and subsequent infection with an adenovirus 12-SV40 virus hybrid. Unlike normal cells, the immortalized cells be cultured continuously in vitro in suitable medium and retain features of normal human bronchial epithelial cells, including the absence of invasive behavior in vitro or in vivo. These cells can also be transfected with oncogenes and used as a model for multistage carcinogenesis, or employed to assay a biological or chemical agent's ability to induce differentiation and carcinogenesis as well as test potential chemotherapeutic agents.

  • Model to study multistage bronchial carcinogenesis
  • Identification of potential chemotherapeutic drugs
  • Identification of carcinogenic agents
