Researchers at Oxford University and the University of Birmingham have made a major breakthrough in cancer treatment by creating the first human bone marrow “organoids” that accurately replicate the key features of human bone marrow. The technology, which is the subject of a patent application filed by the University of Birmingham Enterprise, enables the simultaneous screening of multiple anti-cancer drugs and the testing of personalized treatments for individual cancer patients.
The organoids, which are described in a study recently published in the journal Cancer Discovery, closely mimic the cellular, molecular, and architectural features of myelopoietic (blood cell-producing) bone marrow.
The research also showed that the organoids provide a micro-environment that can accept and support the survival of cells from patients with blood malignancies, including multiple myeloma cells, which are notoriously difficult to maintain outside the human body.
This life-like architecture enabled the team to study how the cells in the bone marrow interact to support normal blood cell production, and how this is disturbed in bone marrow fibrosis (myelofibrosis), where scar tissue builds up in the bone marrow, causing bone marrow failure. Bone marrow fibrosis can develop in patients with certain types of blood cancers and remains incurable.
Senior study author Professor Bethan Psaila, a hematology medical doctor as well as a Research Group Leader at the Radcliffe Department of Medicine, University of Oxford, said “To properly understand how and why blood cancers develop, we need to use experimental systems that closely resemble how real human bone marrow works, which we haven’t really had before. It’s really exciting to now have this terrific system, as finally, we are able to study cancer directly using cells from our patients, rather than relying on animal models or other simpler systems that do not properly show us how the cancer is developing in the bone marrow in actual patients.”
Dr. Khan also added, “This is a huge step forward, enabling insights into the growth patterns of cancer cells and potentially a more personalized approach to treatment. We now have a platform that we can use to test drugs on a ‘personalized medicine’ basis.
“Having developed and validated the model is the first crucial step, and in our ongoing collaborative work we will be working with others to better understand how the bone marrow works in healthy people, and what goes wrong when they have blood diseases.”
Dr. Psaila added, “We hope that this new technique will help accelerate the discovery and testing of new blood cancer treatments, getting improved drugs for our patients to clinical trials faster.”
