Pancreatic cancer-derived exosomes promote tumor metastasis and liver pre-metastatic niche formation
Exosomes play important roles in cell-cell communication, and are likely mediators of the metastatic cascade in cancer. This study examined the role of exosomes in pancreatic cancer cell adhesion, migration, and invasion. We isolated and purified exosomes from two isogenic pancreatic cancer cell lines with different metastatic potentials. Uptake of exosomes from highly metastatic Panc02-H7 cell...
متن کاملExosomes: Mediators of Immune Regulation
Extracellular Vesicles, including exosomes, are small membrane fragments released from many cell types, like Mesenchymal Stem Cells (MSCs). They were recognized as a mechanism of intercellular communication. They can transfer proteins, lipids and nucleic acids to other cells. Thus, they have many physiological (angiogenesis, coagulation and tissue repair, etc.) and pathological (e.g. in autoimm...
متن کاملThe regulation of pre-metastatic niche formation by neutrophils
Metastasis is a multistep process requiring tumor cell detachment from the primary tumor and migration to target organs through the lymphatic or blood circulatory systems. Specific organs are predisposed to metastases in certain cancers and the formation of supportive metastatic microenvironment determines tumor cell homing. Such an environment is provided by a pre-metastatic niche that is form...
متن کاملEngineering the pre-metastatic niche
The pre-metastatic niche - the accumulation of aberrant immune cells and extracellular matrix proteins in target organs - primes the initially healthy organ microenvironment and renders it amenable for subsequent metastatic cell colonization. By attracting metastatic cancer cells, mimics of the pre-metastatic niche offer both diagnostic and therapeutic potential. However, deconstructing the com...
متن کاملS100-SPECT uncovers cellular and molecular events of pre-metastatic niche formation and following organ-specific cancer metastasis
Great progress has been made in in vivo imaging for cancer metastasis. Eisenblaetter et al. developed an innovative S100A8/A9-specific single photon emission computed tomography (SPECT) probe for imaging and succeeded in detecting the metastatic organ favored by the cancer before the cancer arrival. By utilizing this advanced method, researchers have also found that cancer-derived monocytes are...
