Cellular components of the PDAC tumor microenvironment. Diagram of the cellular components of the PDAC tumor microenvironment (1) and adjacent tissue stroma (2). Tumor cells include tumor-associated stromal cells (left upper box); immune-associated compartment (left middle box); and additional cells (bottom box) such as nerve cells, blood and lymphatic vessels cells, and adipocytes. The normal adjacent tissue stroma contains normal stromal cells (upper right box) and immune normal cells (right middle box). Nerve, blood and fat cells are also present in the adjacent stroma (bottom box).
