Micrograph stained cancer cells (IMAGE)
Caption
In this micrograph of ovarian cancer tissue, different elements involved in helping the tumor resist immunotherapy are shown: blue staining marks the cell nucleus, showing the locations of all cells in the image (upper left). Green staining shows a signaling protein called focal adhesion kinase (FAK) that makes tumors more malignant (upper right). Magenta marks T lymphocytes, which are part of the immune response, and red staining indicates an immune-regulating protein called CD155 (bottom left). The bottom right image combines the other three images. Together, they show how ovarian cancer cells build a safe environment around themselves to avoid detection.
