The role of cancer stem cells in the tumors
Scientists previously believed that tumors are lumps of cancer tissue that must be completely removed or destroyed to cure a patient. But over the past few years, researchers have learned that cancer stem cells (CSCs), comprising a small population of cells, appear to be responsible for the initiation, upkeep and relapse of malignant tumors. Even if a tumor is almost completely obliterated, it will regenerate from the surviving CSCs and become even more resistant to treatment than before.
Current therapies, including cell therapy, generally do not target CSCs. This allows CSCs to survive until after chemotherapy or radiation treatments. Killing those cells is a promising strategy to eliminate tumors and prevent them from re-growing.
"The CSCs may explain why common treatments, particularly chemotherapy, are not sufficient to kill tumors. In fact, despite the continuous development of new chemotherapeutic agents, brain tumors can develop and remain resistant to those therapies. The integration of stem cells and immune technologies seems to give us a chance to find out a new way to target at CSCs," says Prof.
"The difficult issue in our project is how to capture and classify CSCs. With our patented technologies, we are able to isolate the CSCs from patient's brain tumor tissues, culture them and induce the multi-drug and radiation resistance. These cells possess very strong carcinogenicity, self-renewal, and also a very strong drug and radiation resistance."
"The outcome of the first pilot study with Johnsen is amazing. The PET-CT scan for Johnsen shows that all the tumor disappeared after the treatment," says Dr.
Dr. Cindy HAO: More clinical trials to confirm the outcome
Cindy HAO, M.D., CEO of Cellonis Biotechnologies is optimistic for the future of this new brain cancer approach. "It gives us a strong confidence to make more efforts toward this direction. This pilot treatment study shows us that the activated immune system can directly kill tumor stem cells as well as tumor daughter cells. But first of all we need to extend our further clinical trials to confirm the outcome. And it also tells us that the future vaccination therapies may be targeted toward Cancer Stem Cell Lysates to improve the antigen-presenting DC response."
