Fig. 1From: Effects of epidermal growth factor receptor kinase inhibition on radiation response in canine osteosarcoma cellsEffects of single agent erlotinib on clonogenic survival. Canine OSA cells treated with erlotinib at 10 μM for 4-6 h (“erlotinib”). Experiments were repeated three times and average of results are shown. Erlotinib showed single agent activity through reduction in clonogenic survival in 2 out of 3 cell lines. * p < 0.05 indicates statistical significant reduction in clonogenic survival compared to controlBack to article page
