Summary of advances in synthesis and application optical ratiometric nano- microparticle sensors for vitro vivo detection pH, oxygen, ROS, ions, biomarkers cell microenvironment.
Summary Complex cellular interactions between the immune system and cancer can impact tumour development, growth, progression. T cells play a key role in these interactions; however, challenge for is to recognize antigens whilst minimizing cross-reactivity with associated healthy tissue. Some cells, including those viral infections, have clear, tumour-specific that be targeted by cells. A high ...
Microfluidic devices allow for precise control of the cellular and noncellular microenvironment at physiologically relevant length- and time-scales. These devices have been shown to mimic the complex in vivo microenvironment better than conventional in vitro assays, and allow real-time monitoring of homotypic or heterotypic cellular interactions. Microfluidic culture platforms enable new assay ...
Transforming Growth Factor-β (TGF-β) signaling in cancer has been termed the "TGF-β paradox", acting as both a tumor suppresser and promoter. The complexity of TGF-β signaling within the tumor is context dependent, and greatly impacted by cellular crosstalk between TGF-β responsive cells in the microenvironment including adjacent epithelial, endothelial, mesenchymal, and hematopoietic cells. He...
The physical microenvironment of tumours is characterized by heterotypic cell interactions and physiological gradients of nutrients, waste products and oxygen. This tumour microenvironment has a major impact on the biology of cancer cells and their response to chemotherapeutic agents. Despite this, most in vitro cancer research still relies primarily on cells grown in 2D and in isolation in nut...
Cells sense a myriad of cues from their surrounding microenvironment to regulate their function. In recent years, it has become clear that physical and mechanical cues are as critical as biochemical factors in regulating cellular function. The geometry of the extracellular matrix (ECM), degree of cell spreading, and ECM rigidity all influence the physical connection between cells and their micr...
