The extracellular matrix (ECM) is a complex network composed of a multitude of different macromolecules. ECM components typically provide a supportive structure to the tissue and engender positional information and crosstalk with neighboring cells in a dynamic reciprocal manner, thereby regulating tissue development and homeostasis. During tumor progression, tumor cells commonly modify and...

Radiotherapy is a well-established therapeutic modality in oncology. It provides survival benefits in several different cancer types. However, cancers relapsing after radiotherapy often develop into more aggressive conditions, which are difficult to treat and are associated with poor prognosis. Cumulating experimental evidence indicates that the irradiated tumor bed contributes to such...

Purpose: Local breast cancer relapse after breast-saving surgery and radiotherapy is associated with increased risk of distant metastasis formation. The mechanisms involved remain largely elusive. We used the well-characterized 4T1 syngeneic, orthotopic breast cancer model to identify novel mechanisms of post-radiation metastasis. Experimental Design: 4T1 cells were injected in 20 Gy...

Radiotherapy is successfully used to treat cancer. Emerging evidence, however, indicates that recurrences after radiotherapy are associated with increased local invasion, metastatic spreading and poor prognosis. Radiation-induced modifications of the tumor microenvironment have been proposed to contribute to increased aggressive tumor behavior, an effect also referred to as tumor bed effect, but...

Cancer-related inflammation has emerged in recent years as a major event contributing to tumor angiogenesis, tumor progression and metastasis formation. Bone marrow-derived and inflammatory cells promote tumor angiogenesis by providing endothelial progenitor cells that differentiate into mature endothelial cells, and by secreting pro-angiogenic factors and remodeling the extracellular matrix...

Tumor-mobilized bone marrow-derived CD11b+ myeloid cells promote tumor angiogenesis, but how and when these cells acquire proangiogenic properties is not fully elucidated. Here we show that CD11b+ myelomonocytic cells develop proangiogenic properties during their differentiation from CD34+ hematopoietic progenitors and that Placenta Growth Factor (PlGF) is critical in promoting this ...
