Chordoid Glioma of the Third Ventricle

Neurospheres grown as 3D cultures constitute a powerful tool to study glioma biology. Here we present a protocol to perform immunohistochemistry while maintaining the 3D structure of glioma neurospheres through paraffin embedding. This method enables the characterization of glioma neurosphere properties such as stemness and neural...

IDH1-mutant diffuse low-grade gliomas are rare tumors that are difficult to culture. We introduce a simple, non-enzymatic explant method that preserves IDH1-mutant protein expression and sustains cultures for months. Importantly, this technique works with cryopreserved tumors, offering a valuable resource for glioma...

After neural tube formation, the neuroepithelium constricts and folds while the tube fills with embryonic cerebrospinal fluid (eCSF) to form the embryonic brain ventricles. We developed this ventricle injection technique to better visualize the fluid filled space in contrast to the neuroepithelial shape in a live...

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

By combining a polished and reinforced thin-skull (PoRTS) cranial window and glioblastoma (GBM) cell injection, we can observe glioma initiation and growth from injected GBM cells in the brain of a live mouse...

This video demonstrates the assessment of neuronal electrical activity in a co-culture of hiPSC-derived cortical glutamatergic neurons and glioma cells using a microfluidic device with multielectrode...
