Figure 7From: Functional interaction between Envoncogene from Jaagsiekte sheep retrovirus and tumor suppressor Sprouty2Sprouty2 overexpressing cells are resistant to Env -mediated transformation. A549, A549-Spr, BEAS-2B and BEAS-2B-Spr cells were transfected with the plasmid carrying Env gene by standard calcium chloride method. Foci formation after 14 days was monitored and photographed at 10× magnification.Back to article page
