Grafts of GSCs Into Brain Organoids for Testing Anti-invasion Drugs

Not Applicable

Recruiting

• Conditions: Glioma, Malignant; Glioblastoma
• Interventions: Other: Biological sample collection

• Registration Number: NCT05772741
• Lead Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Brief Summary

In patients operated for glioblastoma, glioma stem-like cell lines will be obtained from tumor tissue, and IPSCs from skin fibroblasts or PBMCs. Brain organoids will be generated from IPSCs and co-cultured with IPSCs to study brain invasion and ciliogenesis. 3D genome architecture of glioma stem-like cells will be investigated. Gene modulation and pharmacologic strategies to inhibit invasion and restore ciliogenesis will be explored.

Inclusion Criteria

o be enrolled in the study patients must:

1. Have a radiological diagnosis of supratentorial glioblastoma, or
2. Have a radiological diagnosis of first recurrence of a primary supratentorial glioblastoma (for which a formal histopathologic diagnosis of glioblastoma had made at first surgery), according with RANO criteria (Wen, 2010);

Exclusion criteria

To be enrolled in the study patients must not:

1. Have not enough pathological material removed at surgery available both for mandatory routine histopathological diagnosis and for the present study, as judged by the Principal Investigator;
2. Have not a definitive pathological diagnosis of a primary supratentorial glioblastoma, according with 2016 WHO classification.
