Lab-grown tumors respond to cell therapy the same as tumors in the patients’ brains, according to Penn researchers
PHILADELPHIA— For the first time, researchers used lab-grown organoids created from tumors of individuals with glioblastoma (GBM) to accurately model a patient’s response to CAR T cell therapy in real time. The organoid’s response to therapy mirrored the response of the actual tumor in the patient’s brain. That is, if the tumor-derived organoid shrunk after treatment, so did the patient’s actual tumor, according to new research from the Perelman School of Medicine at the University of Pennsylvania, published today in Cell Stem Cell.
