Hypothesis
What influence does the radial glial grid exert on the navigation of interneurons within the developing cerebral cortex?
Conclusion
Interactions with radial glial cells significantly influence the migration and positioning of interneurons in the developing cerebral cortex.
Supporting Evidence
- Interneurons migrate tangentially into the developing cerebral wall.
- Dynamic interactions with radial glia can influence the trajectory of interneuronal migration.
- Local interneuronal migration occurs in multiple directions across the cerebral wall.
Takeaway
This study shows that brain cells called interneurons move around in the developing brain and can change direction based on their interactions with other cells called radial glia.
Methodology
Live imaging of genetically defined populations of interneurons and radial glia in developing mouse embryos using two-photon microscopy.
Limitations
The study primarily focuses on a specific mouse model and may not fully represent human neurodevelopment.
Participant Demographics
Embryonic day 16 Dlx5/6-cre-IRES-EGFP mice were used for the study.
