Neuronal Stem Cells (image) North Carolina State University Share Print E-Mail Caption This is a rendered image of a primary neuronal stem cell culture in which cells were labeled with different fluorescently labeled proteins that differentiate between stem cells (orange/yellow) and their neuronal 'offspring' (blue/green/purple). Neural stem cells are dependent on a protein called Sp2 for their ability to generate neurons.
