Cancer-stroma interactions

When we think of cancer, we mostly think of cells constituting the neoplastic part of cancer. But a cancerous lesion consists of many other cell types, which could resist, or help in its progression. These “stromal cells” consist of activated fibroblasts, macrophages, endothelial cells, as well as the specialized environment modulated by these cells. In our lab, we attempt to systematically understand how cancer and stromal cells interact with each other using a variety of approaches, including microfluidics, nanotechnology, live cell imaging, and genetic screens. We aim to elucidate the mechanisms through which stroma facilitates cancer to grow, become invasive, and resistant to chemotherapeutic drugs.

Communication between cancer cells and those in the stroma (consisting of cancer associated fibroblasts [CAFs], macrophages, other immune cells etc.) regulate many steps in the metastatic cascade, including initial dissemination, stromal invasion, tropism etc. These interactions, like all cellular phenotypes, are contextual and dynamic, bearing different kinetic profiles. These distinct secretory signatures could be interpreted specifically by the receiving cells to elicit a functional response. We use a variety of tools in our lab, including microfluidics, live cell imaging, and computational analysis to understand the nature of communication between cancer and stromal cells.
