TICs (IMAGE) Institute for Basic Science Caption Tumor initiating cells (TICs, in red) are resistant to conventional chemo and radiation therapies. They are able to repopulate the tumor (grey) causing relapse and metastasis. The scientists have developed TiY, a fluorescent sensor with drug-like properties that targets TICs specifically. It could be used to visualize and suppress TICs within the tissue without the need of biopsy.
