Metastatic breast cancer cells might use
bone marrow-derived mesenchymal stem cells (MSCs) to help them spread to
bone tissue. A study using a 3D scaffold model has shown how this happens.
The findings suggest that breast
tumor-derived factors can promote the maturation of MSCs into bone
cells, and that mechanical compression of the scaffold further
stimulates bone development. The article is published in Tissue Engineering.

Lifestyle choices may or may not cause breast cancer but healthy lifestyle changes can open up avenues beyond breast cancer. Good habits will allow one to fight breast cancer and to live with dignity.

Maureen Lynch, Claudia Fischbach, and coauthors from Cornell University (Ithaca, NY) and University of Massachusetts Amherst used a mineral-containing 3D scaffold as an in vitro model to study whether factors such as breast tumor-derived compounds and mechanical stimulation within the bone microenvironment affect the interactions between metastatic cancer cells and bone.
Understanding and intervening
in these interactions could have clinical implications for the nearly
75% of patients with advanced breast cancer in whom incurable skeletal
metastatic disease develops.

Management of breast cancer during pregnancy or pregnancy associated breast cancer requires special consideration to avoid harm to the fetus.
The article entitled "Three-Dimensional Mechanical Loading Modulates the Osteogenic Response of Mesenchymal Stem Cells to Tumor-Derived Soluble Signals" describes the composition of the scaffold, the study design, and how this model can be used to evaluate the role of certain physical cues on bone metastatic breast cancer.
"The article reports a very exciting study leveraging a tissue-engineered tumor model for controlled interrogation of tumor-bone interactions with enormous implications for the development of new therapeutics" says Co-Editor-in-Chief Antonios G. Mikos, Louis Calder Professor at Rice University, Houston, TX.
