Nestin+ cells interaction with microglia and astrocytes in perivascular space of malignant peripheral nerve sheath tumors
Malignant peripheral trigeminal sheath tumor (MPNST) spreads to the brain parenchyma via the perivascular space (PVS). Nestin-expressing neoplastic cells lead tumor progression. Tumor-associated macrophages and microglia (TAMs) are a critical immune cells population for promoting this progression. In this work, we study the distribution of Nestin+ cells and TAMs in the infiltrative perivascular spaces of endogenous rat MPNSTs.MPNSTs are induced in Sprague Dawley rats by prenatal exposure of N-Ethyl N-nitrosourea (ENU). Tumor screening is performed by T1-w Magnetic Resonance Imaging and by immu
