Mutant receptors made in one tumor cell can be passed to tumor cells lacking them.

In this study, the authors found that glioma cells expressing EGFRvIII transferred this errant receptor to nonexpressing cells via microvesicles--small plasma membrane buds. The microvesicles were produced in abundance by the mutant expressing cells and were widely taken up by receptor-negative cells
