The effect of plinabulin on tumour surviving fraction and the induction of necrosis in the KHT sarcoma. Top panel: Tumour surviving fraction was determined using the clonogenic survival assay 24 hours after injecting different doses of plinabulin. Middle panel: The degree of tumour necrosis was determined from histological sections 24 hours after injecting plinabulin. Bottom panel: Tumour surviving fraction was determined using the clonogenic survival assay 24 hours after local tumour irradiation with different radiation doses either given alone (○) or 1 hour prior to injecting the mice with 2.5 mg/kg plinabulin (●). Results show mean values (± 1 S.E.) from at least 3 animals. Asterisks indicate values statistically different from controls.
