Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction. Most pheochromocytomas are functional tumors and produce excess epinephrine and norepinephrine. Mice more commonly have mammary adenocarcinomas. These tumors can become malignant within weeks, too. NSG has emerged as the preferred platform for studying the frequency and characteristics of cancer stem cells.
