Figure 1From: Expression of seven stem-cell-associated markers in human airway biopsy specimens obtained via fiberoptic bronchoscopyExample RT-PCR bands of human lung cancer and non-lung cancer biopsy tissues obtained from bronchoscopy. Total RNAs were isolated and reverse transcribed to cDNA from the biopsy tissues. RT-PCR Products of β-actin and stem-cell-associated markers were run on 2% agarose gels with ethidium bromide.Back to article page
