Abstract

Math1 is a bHLH transcription factor expressed in neural progenitor cells in multiple regions of the nervous system. Previously we identified a Math1 enhancer that directs expression of reporter genes in a Math1 specific pattern [Development 127 (2000) 1185]. We have used a portion of this enhancer to drive expression of a nuclear GFP reporter in the Math1 lineage in transgenic mice. In this transgenic mouse strain, GFP is expressed in Math1 domains in the (1). developing spinal cord in progenitors to dI1 dorsal interneurons, (2). granule-cell progenitors in the developing cerebellum, (3). Merkel cells in the skin, and (4). hair cells in the developing vestibular and auditory systems. Furthermore, non-Math1 related expression is detected that is likely due to the absence of inhibitory regulatory sequences from the transgene. These expression domains include (1). the apical ectodermal ridge in developing limbs, (2). post-mitotic cells in the developing cortex and spinal cord, (3). the dentate gyrus, (4). retina, and (5). olfactory epithelium. Because GFP marks specific neuronal cell types in living tissue, this transgenic strain is a powerful tool for future studies on the development and electrophysiological properties of distinct cell types in the central nervous system and in sensory systems.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SOX2+ nuclei speckles in the skin epithelium were Atoh1/nGFP+ ISL1+ cells that arose in the epithelium between days 14-16, reminiscent of Merkel cells.

    “Moreover, as mentioned earlier in Figure 4D′, the SOX2+ nuclei speckles in the skin epithelium were Atoh1/nGFP+ ISL1+ cells that arose in the epithelium between days 14–16 (Figure 5F–F″), reminiscence of Merkel cells, which are touch sensing cells in the epidermis (Lumpkin et al., 2003; Perdigoto et al., 2014).”

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.
