3D brain tumor organoids provide new scientific opportunities for research community

MedicalXpress | апр 15, 2026

Efforts to identify and evaluate next-generation therapeutics for pediatric brain tumors are easily stymied by the quality and availability of laboratory models for research. To address this issue, scientists at St. Jude Children's Research Hospital have developed patient-derived tumor organoids and tumor organoid xenografts that accurately reflect the biologic underpinnings of embryonal brain tumors. These models utilize the latest technical advances, allowing researchers to perform functional assays and preclinical drug testing faster without relying on newly obtained tumor samples. The models are available to other researchers upon request, providing a resource to help advance the field. The work appears in Science Advances.
