Greater than 30% of mice injected with cells expressing C5a have complete regression of their tumors. Mice were injected as in Fig. 4. Mice were considered tumor bearing when the mean leg diameter was less than 5.0 mm and the number with tumor versus the total number injected is presented. The data are a composite of four separate experiments. Open circles, mice injected with control tumors; solid squares, mice injected with C5a-expressing clone A1 tumor cells
