Identifying targets and resistance mechanisms resulting from intra-tumor heterogeneity

Anuja Sathe

Tumors consist of multiple sub-populations with distinct phenotypes that confer growth advantages. Moreover, they are not isolated masses of cancer cells but are surrounded by a unique microenvironment composed of different cell types. We aim to characterize this heterogeneity by utilizing various single-cell sequencing approaches. By identifying unique cell types and states in patient tumors, we will identify novel targets in the tumor micro-environment. We will also identify resistance mechanisms to various treatments by using different experimental model systems.
