Brain Tumor Stem Cell (BTSC) Migration Assay for Drug Treatment Studies: An In Vitro Live-cell Imaging Technique to Analyze the Effect of Drug Treatment on Migration of BTSCs
In this video, we perform brain tumor stem cell migration assay to analyze the effect of the drug of interest on the migration of live brain tumor stem cells using chemotaxis migration plate. Live-cell imaging facilitates the visualization and quantification of cell migration during the assay.
Protocol
1. Brain Tumor Stem Cell Migration Assay Seed 200,000 cells in a T25 flask in 8 mL of complete media 1–2 weeks before planning to perform a migration assay. NOTE: The time between plating and performing the assay will vary depending on the growth rate of the BTSC culture used. To test the effect of a drug treatment on migration, pretreat the cells with the appropriate vehicle, such as DMSO, and drug of interest by adding applicable volumes of the vehi…
Representative Results
Figure 1: Live-cell imaging of a BTSC migration. (A) This is an example of a 96-well chemotaxis migration plate coated with a thin layer of type I collagen prior to performing the migration assay with BTSCs. The images show i) a plate with all three parts (lid, membrane insert, and reservoir) placed together, ii) all three parts separated, iii) a close-up image o…
