What are Glial Restricted Precursors?
GRPs are progenitor cells that can differentiate into oligodendrocytes, crucial for myelination in the nervous system.
Why is visual demonstration important in this protocol?
Visual aids help clarify complex surgical steps, making it easier for inexperienced researchers to learn the technique.
How are GRPs maintained in culture?
GRPs are cultured in GRP Selective Media and require regular media changes to maintain cell health.
What is the significance of using E 13 fetuses?
E 13 fetuses provide a suitable source of spinal cords rich in GRPs for extraction and study.
Can GRPs be stored for long periods?
Yes, GRPs can be frozen and stored long-term, maintaining viability for future experiments.
