During the growth and study of NSCs, a range of molecules present on the
surface of multipotent neural stem and progenitor cells (NSCs) were
identified. These markers were identified using a number of human and
murine neural stem cell lines, including retinal stem cells (RSCs). The
NSC-specific markers identified included gene products as well as
non-protein molecules and sugar epitopes not directly coded in the
genome. Together with surface markers which were determined to be absent
from the surface of hNSCs, the molecules described herein provide a means
to enrich for neural stem cells, or neural progenitor subpopulations,
particularly using combinatorial cell sorting strategies. These same
molecules also represent targets for pharmacological manipulation of NSC
populations and subpopulations, both in vivo and ex vivo. Furthermore,
these molecules provide potential targets for therapeutic manipulation of
other neural precursor-related cell types including malignant cell types
as well as diseases originating from, or preferentially affecting,
various uncommitted or replication-competent cell types.
