Knowledge of colorectal cancer biology is improving how we approach cancer treatment. Specifically, the tumor microenvironment and abnormal angiogenesis are of particular interest. Optical methods are a prime candidate for research of the tumor microenvironment due to their ability to quantitively assess tissue structure and perfusion in real time. Particularly, the “transport scattering regime” has been identified as a method of obtaining high-resolution images and reflectance spectroscopy data; this light scattering regime has been demonstrated compatible with endoscopic imaging systems. In this study, a proof-of-concept optical imaging system is presented, capable of resolving absorbers within scattering turbid media using a …

When cancer metastasizes from a primary tumor site to secondary site through the bloodstream or lymph, the cancer becomes more difficult to treat. For this reason, it is vital to study what indicates the metastatic potential of a tumor. Current research has shown that cell lines with high metastatic potential display increased levels of metabolic adaptability over their nonmetastatic counterparts after undergoing hypoxic conditions. One method of assessing this adaptability is to measure the concentration of reactive oxygen species (ROS) produced by the cells while undergoing oxidative stress. In highly adaptable metastatic cells, an increase of ROS buildup within the …

The development of complex structures and organs by multicellular organisms relies on the ability of epithelial cells to self-organize. Epithelia are sheets of connected cells, and compartment boundaries are formed between certain epithelial cells to create distinct tissue compartments. Compartment boundaries are specialized cell-cell interfaces that are enriched for the cytoskeletal proteins actin and myosin, leading to straight cell edges under relatively high tension that act as fences keep cells from moving between compartments. In the model organism Drosophila melanogaster (fruit fly), compartment boundaries in the early embryo are established in response to the non-uniform striped expression of the cell-surface …
