简介：
Overview
This article presents a screening protocol for identifying small molecules that promote astroglial differentiation in glioblastoma stem cells (GSCs). The method utilizes a stem cell differentiation reporter, where enhanced GFP (eGFP) expression is driven by the human GFAP promoter.
Key Study Components
Area of Science
- Neuroscience
- Cancer Biology
- Stem Cell Research
Background
- Glioblastoma stem cells (GSCs) are crucial in understanding glioblastoma recurrence.
- Identifying pathways that maintain GSCs in an undifferentiated state is essential.
