Premalignant lesions of the bronchial epithelium

Transcriptional profiling of hyperplastic, metaplastic, and dysplastic lesions of the bronchus in comparison with normal bronchial epithelium. The aim was to identify transcripts and cell signalling pathways associated with the development of isolated premalignant lesions and/or lesions combined with each other in the same bronchial epithelium. Basal cell hyperplasia (n=4), squamous metaplasia (n=4), and dysplasia (n=1) vs. normal bronchial epithelial cells (n=1)
