How will the RNAi be derived?... From human embryos?

The RNA will come from the specific target cells in the adult.

Thank you for the rational reply! I had hoped the RNA for treating cervical cancer would be derieved from the target cervix, the target throat tissue, the target lung tissue. I still do not fully understand how the fruit fly embryos were source for the siRNA, for RNAi testing the interference with PV lifecycle in the fruit fly.
