Figure 3 shows the mRNA barcode counts for TGFβ-1 as well as other highly expressed molecules such as IL-8 and VEGF as collected from confluent cultures of the three melanoma lines (NZM7, NZM48, NZM74 and the brain endothelial cells, hCMVECs–black bars). The gene discussed is CXCL8; the disease is melanoma.
