Thoracic aorta dissected, cut into 2mm rings, washed 12 times in serum free EBM (Cambrex BioScience) and cultured for 13 days in serum free-EBM, changing medium every third day.
On day 13 , recombinant human VEGF protein (R&D Systems #293-VE) added to the culture at a final concentration of 10ng/ml in 0.5ml EBM
Extracted molecule
total RNA
Extraction protocol
20 hours after treatment with VEGF, four to six individual rings were combined, snap frozen in liquid nitrogen, crushed, and extracted with Trizol reagent (Invitrogen) followed by RNAEasy Micro kit (Qiagen) purification with DNAse I treatment. Total RNA eluted into DEPC water.
