  • Pancreatic fractions enriched in duct cells or islet cells from the same donor were compared for their IL-8 and VEGF expression. Cells were retrieved from culture, total RNA extracted, and reverse transcribed to cDNA. IL-8 and VEGF expression levels were measured by real-time PCR and normalized to HPRT (donor numbers 1–3). Islet-enriched preparations were dissociated into single cells and fluorescence-activated cell sorted into duct cell–purified and endocrine cell–purified preparations prior to comparing their IL-8 and VEGF expression (donor numbers 4–6).
