['To understand the basis of nervous system development, we must learn how multipotent progenitors generate diverse neuronal and glial lineages. We addressed this issue in the zebrafish enteric nervous system (ENS), a complex neuronal and glial network that regulates essential intestinal functions. Little is currently known about how ENS progenitor subpopulations generate enteric neuronal and glial diversity.', 'We identified temporally and spatially dependent progenitor subpopulations based on coexpression of three genes essential for normal ENS development: phox2bb, sox10, and ret. Our data suggest that combinatorial expression of these genes delineates three major ENS progenitor subpopulations, (1) phox2bb\u2009+\u2009/ret- /sox10-, (2) phox2bb\u2009+\u2009/ret\u2009+\u2009/sox10-, and (3) phox2bb\u2009+\u2009/ret\u2009+\u2009/sox10+, that reflect temporal progression of progenitor maturation during migration. We also found that differentiating zebrafish neurons maintain phox2bb and ret expression, and lose sox10 expression.'] Does molecular fingerprinting delineate progenitor populations in the developing zebrafish enteric nervous system?
