Abstract

Neural stem cells can generate in vitro progenitors of the three main cell lineages found in the CNS. The signaling pathways underlying the acquisition of differentiated phenotypes in these cells are poorly understood. Here we tested the hypothesis that Ca(2+) signaling controls differentiation of neural precursors. We found low-frequency global and local Ca(2+) transients occurring predominantly during early stages of differentiation. Spontaneous Ca(2+) signals in individual precursors were not synchronized with Ca(2+) transients in surrounding cells. Experimentally induced changes in the frequency of local Ca(2+) signals and global Ca(2+) rises correlated positively with neurite outgrowth and the onset of GABAergic neurotransmitter phenotype, respectively. NMDA receptor activity was critical for alterations in neuronal morphology but not for the timing of the acquisition of the neurotransmitter phenotype. Thus, spontaneous Ca(2+) signals are an intrinsic property of differentiating neurosphere-derived precursors. Their frequency may specify neuronal morphology and acquisition of neurotransmitter phenotype.

  • CYFIP1 regulation of calcium channel subunits compromises intracellular calcium levels, resulting in delayed axonal development.

    “These findings support our model in which CYFIP1 regulation of calcium channel subunits compromise intracellular calcium levels, resulting in delayed axonal development10,84,85 (Fig. 7).”

    From CYFIP1 governs the development of cortical axons by modulating calcium availability (2025) · cites this paper as [84]

    The Results section (page not specified in our copy) reports that low-calcium conditions significantly shortened neurites in differentiating neural precursors. That supports the calcium–outgrowth link, but the paper does not establish that CYFIP1 regulates calcium-channel subunits or that this mechanism delays axonal development. (LLM, conf=0.88)

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.
