Isolation and characterization of neural precursor cells from the Sox1-GFP reporter mouse

Abstract

We have made use of a reporter mouse line in which enhanced green fluorescence protein (GFP) is inserted into the Sox1 locus. We show that the GFP reporter is coexpressed with the Sox1 protein as well as with other known markers for neural stem and progenitor cells, and can be used to identify and isolate these cells by fluorescence-activated cell sorting (FACS) from the developing or adult brain and from neurosphere cultures. All neurosphere-forming cells with the capacity for multipotency and self-renewal reside in the Sox1-GFP-expressing population. Thus, the Sox1-GFP reporter system is highly useful for identification, isolation and characterization of neural stem and progenitor cells, a..
