Co-culturing Glutamatergic Neurons and Pediatric High-Grade Glioma Cells

This video showcases a technique for co-culturing glutamatergic neurons and pediatric high-grade glioma (pHGG) cells within a microfluidic device. Human induced pluripotent stem cells are introduced into the microfluidic system and incubated to promote their differentiation into mature cortical glutamatergic neurons. Following this, the pHGG cells are introduced onto the mature neurons, establishing a co-culture and enabling interactions between neurons and pHGG...

Graded Potential01:19

Graded Potential

Graded potentials are localized fluctuations in the cell membrane's electrical charge, commonly found in the dendrites of neurons. The magnitude of these potential changes depends on the strength of the initiating stimulus. In a membrane at its resting potential, a graded potential signifies a voltage shift either above -70 mV or below -70 mV.
Graded potentials fall into two categories: depolarizing and hyperpolarizing. Depolarizing graded potentials typically occur when sodium (Na+) or...

A Protocol for Explant Cultures of IDH1-mutant Diffuse Low-grade Gliomas06:27

A Protocol for Explant Cultures of IDH1-mutant Diffuse Low-grade Gliomas

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...

Optimization of High Grade Glioma Cell Culture from Surgical Specimens for Use in Clinically Relevant Animal Models and 3D Immunochemistry

Protocol for propagation of dissociated high grade glioma surgical specimens in serum-free neurosphere medium to select for cells with cancer stem cell phenotype. For specimens that fail to grow as neurospheres, an alternative protocol is suggested. A paraffin embedding technique for maintaining the 3D neurosphere architecture for immunocytochemistry is...

A Rapid Screening Workflow to Identify Potential Combination Therapy for GBM using Patient-Derived Glioma Stem Cells05:29

A Rapid Screening Workflow to Identify Potential Combination Therapy for GBM using Patient-Derived Glioma Stem Cells

The glioma stem cells (GSCs) are a small fraction of cancer cells which play essential roles in tumor initiation, angiogenesis, and drug resistance in glioblastoma (GBM), the most prevalent and devastating primary brain tumor. The presence of GSCs makes the GBM very refractory to most of individual targeted agents, so high-throughput screening methods are required to identify potential effective combination therapeutics. The protocol describes a simple workflow to enable rapid screening for...
