Cryptic boundaries in roof plate and choroid plexus identified by intersectional gene activation

Abstract

The hindbrain roof plate and choroid plexus are essential organizing centers for inducing dorsal neuron fates and sustaining neuron function. To map the formation of these structures, we developed a broadly applicable, high resolution, recombinase-based method for mapping the fate of cells originating from coordinates defined by intersecting combinations of expressed genes. Using this method, we show that distinct regions of hindbrain roof plate originate from discrete subdomains of rhombencephalic neuroectoderm expressing Wnt1; that choroid plexus, a secretory epithelium important for patterning later-formed hindbrain structures and maintaining neuron function, derives from the same embryonic primordium as the hindbrain roof plate; and that, unlike the floor plate, these dorsal organizing centers develop in a patterned, segmental manner, built from lineage-restricted compartments. Our data suggest that the roof plate and choroid plexus may be formed of functional units that are capable of differentially organizing the generation of distinct neuronal cell types at different axial levels.

  • Gene programs and graded expression patterns, particularly across 4V choroid plexus epithelial cells, may arise from the segmental development of the 4V choroid plexus from distinct rhombomeres.

    “Gene programs and graded expression patterns, particularly across 4V ChP epithelial cells, may arise from the segmental development of the 4V ChP from distinct rhombomeres (Awatramani et al., 2003; Hunter and Dymecki, 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
