This image captures the morphological transformation of patient-derived glioblastoma cells exposed to different growth media conditions. Normally round and intact, the cell nuclei (blue) appear fragmented as vimentin fibers (red)—a protein critical for structural integrity—expand and dominate the field of view. Once compact and clustered, the cells now extend long neurite-like projections, forming an interwoven web that evokes signals passing between a tumor’s “thoughts.”

Part of the Human Cancer Model Initiative, this work highlights how the cellular microenvironment reshapes cancer behavior and supports the development of next-generation, clinically faithful cancer models.
