text: The cyclin-dependent kinase inhibitor p57KIP2 is encoded by the imprinted
Cdkn1c locus, exhibits maternal expression, and is essential for cerebral cortex
development. How Cdkn1c regulates corticogenesis is however not clear. To this
end we employ Mosaic Analysis with Double Markers (MADM) technology to genetically
dissect Cdkn1c gene function in corticogenesis at single cell resolution. We find
that the previously described growth-inhibitory Cdkn1c function is a non-cell-autonomous
one, acting on the whole organism. In contrast we reveal a growth-promoting cell-autonomous
Cdkn1c function which at the mechanistic level mediates radial glial progenitor
cell and nascent projection neuron survival. Strikingly, the growth-promoting
function of Cdkn1c is highly dosage sensitive but not subject to genomic imprinting.
Collectively, our results suggest that the Cdkn1c locus regulates cortical development
through distinct cell-autonomous and non-cell-autonomous mechanisms. More generally,
our study highlights the importance to probe the relative contributions of cell
intrinsic gene function and tissue-wide mechanisms to the overall phenotype.
