Cancer Cells in Mice May Hitch a Ride with Bone-Healing Stem Cells

Case studies revealing bone transition following oral implant surgical treatments, as well as epidemiological research studies showing the risk of bone transition increases after experiencing bone fractures, have actually led scientists to presume that the process of bone renovation after an injury might jumpstart cancer cell department.” This is a really essential study because it validates clinical information which reveal that increased bone resorption promotes tumor development in bone, and it supplies a mechanism by which this can happen,” Theresa A. Guise, a cancer researcher who studies mechanisms of bone transition at the University of Texas MD Anderson Cancer Center and who was not included in this work, composes in an email to The Scientist. In additional experiments, mice with diminished NG2+ stem cells experienced less bone colonization of DTCs even in the absence of fractures, recommending that even homeostatic bone remodeling, which occurs continually, may exacerbate bone metastasis.

Case research studies revealing bone transition following oral implant surgical treatments, as well as epidemiological research studies suggesting the danger of bone transition increases after experiencing bone fractures, have actually led researchers to posit that the procedure of bone improvement after an injury could boost cancer cell department.” This is an extremely important study due to the fact that it validates clinical information which show that increased bone resorption promotes tumor growth in bone, and it provides a system by which this can happen,” Theresa A. Guise, a cancer researcher who studies systems of bone transition at the University of Texas MD Anderson Cancer Center and who was not included in this work, composes in an e-mail to The Scientist. Injured femurs from mice with lowered levels of NG2+ cells– a type of stem cell that can differentiate into bone-forming osteoblasts– showed less bone metastasis than fractured bones from mice with normal levels of these cells, suggesting that the cells play a role in communicating cancer cells to fracture websites. In more experiments, mice with diminished NG2+ stem cells experienced less bone colonization of DTCs even in the lack of fractures, suggesting that even homeostatic bone improvement, which takes place constantly, might intensify bone transition. Interrupting the connection in between cadherin molecules might do more than prevent bone transition, Zhang states, because as tumors grow, DTCs can move out of the bone and into other organs, where they might again metastasize.
