Bone marrow-derived cells (BMDCs) participate in the growth and spread of tumors of the breast, brain, lung, and stomach. To examine the role of BMDCs, researchers developed a mouse model that could be used to track the migration of these cells while tumors formed and expanded. Their results, published in the November issue of The American Journal of Pathology, strongly suggest that more effective cancer treatments may be developed by exploiting the mechanism by which bone marrow cells migrate to tumors and retard their proliferation.
