  • Description: Primary Human bronchial epithelial cells when grown in vitro have a limited lifespan and begin to deviate both in phenotype and morphology, losing the plasticity required around passage 4 or 5, for air-liquid interface (ALI) differentiation. These Human bronchial epithelial cells expressing BMI-1 retain both viability and differentiation potential of wild-type human bronchial epithelium while importantly not demonstrating changes in cell karyotype. B lymphoma Moloney murine leukemia virus insertion region 1 homolog (BMI-1) is an oncogene which functions by regulating P16 and P19 cell cycle inhibitor genes and is also associated with erythroplakia and tongue cancer. BMI-1 is thought to repress, p16(Ink4a), a cyclin-dependent kinase inhibitor and tumor suppressor that induces cell cycle arrest at the Gap 1 phase. BMI-1 can therefore be used to delay cell senescence. The airway epithelium is a critical interface acting as a barrier to potential pathogens and extraneous particles, assisting in regulation of host defense mechanisms like the inflammatory response.
