Exosomes Released from Breast Cancer Carcinomas Stimulate Cell Movement
For metastasis to occur cells must communicate with to their local environment to initiate growth and invasion. Exosomes have emerged as an important mediator of cell-to-cell signalling through the transfer of molecules such as mRNAs, microRNAs, and proteins between cells. Exosomes have been proposed to act as regulators of cancer progression. Here, we study the effect of exosomes on cell migra...
متن کاملNK cell-released exosomes
We have recently reported that human natural killer (NK) cells release exosomes that express both NK-cell markers and cytotoxic molecules. Similar results were obtained with circulating exosomes from human healthy donors. Both NK-cell derived and circulating exosomes exerted a full functional activity and killed both tumor and activated immune cells. These findings indicate that NK-cell derived...
متن کاملMesenchymal Stem Cell-Derived Exosomes Stimulate Cycling Quiescence and Early Breast Cancer Dormancy in Bone Marrow.
Dormant breast cancers resurge as metastatic disease after a long dormancy period in the bone marrow, where cancer cells interact with mesenchymal stem cells (MSC). However, the nature of early interactions between breast cancer cells and MSCs in the bone marrow microenvironment that facilitate adaptation to a quiescent state remains poorly understood. Here, we report that breast cancer cells p...
متن کاملOral squamous cell carcinomas stimulate osteoclast differentiation.
Matrix metalloproteinases (MMPs) play important roles in the invasion and metastasis to soft tissues of carcinomas including, oral squamous cell carcinomas (SCCs). Although, osteoclastic bone resorption is an important step in bone involvement in a variety of malignancies, the mechanism of bone involvement of oral SCC remains unclear. Once cancer cells arrest in bone, the bone is a storehouse o...
متن کاملExpression of B-cell surface antigens in subpopulations of exosomes released from B-cell lymphoma cells.
PURPOSE Exosomes are small (30- to 100-nm) vesicles secreted by all cell types in culture and found in most body fluids. A mean of 1 mL of blood serum, derived from healthy donors, contains approximately 10(12) exosomes. Depending on the disease, the number of exosomes can fluctuate. Concentration of exosomes in the bloodstream and all other body fluids is extremely high. Several B-cell surface...
