Mosaic analysis with a repressible cell marker (MARCM) for Drosophila neural development

Trends Neurosci. 2001 May;24(5):251-4. doi: 10.1016/s0166-2236(00)01791-4.


We have modified an FLP/FRT-based genetic mosaic system to label either neurons derived from a common progenitor or isolated single neurons, in the Drosophila CNS. These uniquely labeled neurons can also be made homozygous for a mutation of interest within an otherwise phenotypically wild-type brain. Using this new mosaic system, not only can normal brain development be described with unprecedented single cell resolution, but also the underlying molecular mechanisms can be investigated by identifying genes that are required for these developmental processes.
