Understanding tumor microenvironment with photoacoustic spectral analysis
Tumors are not just isolated clumps of abnormal cells but are associated with more complex system known as the “tumor microenvironment” (TME). Over the past few years, research has revealed that the TME consists of a complex combination of blood vessels, connective tissue, and a matrix of extracellular proteins and molecules. Most importantly, the composition of the TME is different from that of nearby healthy tissues. In particular, the lipid and collagen contents of tumors differ from those of normal tissues, making them important potential biomarkers for diagnosing various types of ...
