The disclosure relates to an isolated regulatory sequence for Tctex-1 that is transcriptionally active in adult neural progenitor and stem cells, including Type 1, Type 2 and Type 3 progenitors, as well as during development. The disclosure also relates to a method for selectively expressing a genetic sequence in neural progenitor cells. The disclosure of inserting and expressing a specific sequence in these cells allows marking, identification, sorting, tracking, and manipulating neural progenitor and stem cells.
