Abstract

Down syndrome (trisomy 21) is the most common viable chromosomal disorder with intellectual impairment and several other developmental abnormalities. Here, we report the generation and characterization of induced pluripotent stem cells (iPSCs) derived from monozygotic twins discordant for trisomy 21 in order to eliminate the effects of the variability of genomic background. The alterations observed by genetic analysis at the iPSC level and at first approximation in early development illustrate the developmental disease transcriptional signature of Down syndrome. Moreover, we observed an abnormal neural differentiation of Down syndrome iPSCs in vivo when formed teratoma in NOD‐SCID mice, and in vitro when differentiated into neuroprogenitors and neurons. These defects were associated with changes in the architecture and density of neurons, astroglial and oligodendroglial cells together with misexpression of genes involved in neurogenesis, lineage specification and differentiation. Furthermore, we provide novel evidence that dual‐specificity tyrosine‐( Y )‐phosphorylation regulated kinase 1 A ( DYRK1A ) on chromosome 21 likely contributes to these defects. Importantly, we found that targeting DYRK1A pharmacologically or by shRNA results in a considerable correction of these defects.

  • Results from induced pluripotent stem cell studies of neurogenesis are discordant: the generation of neurons from induced pluripotent stem cells has been reported in some studies to be impaired and in others not to be impaired, which may be explained by technical differences in the cell lines and protocols used.

    “However, results from these studies are discordant: the generation of neurons from iPSCs has been reported in some studies to be impaired74,77–79 and in others not to be impaired75,80,81, which may be explained by technical differences in the cell lines and protocols used (see Box 1).”

  • Analyses of neural progenitor cells arising from trisomy 21 induced pluripotent stem cells have provided conflicting data, with some suggesting that apoptosis is increased and others seeing no effect.

    “Analyses of NPCs arising from T21 iPSCs have provided conflicting data, with some suggesting that apoptosis is increased74,79,95 and others seeing no effect75,77,81,96.”
  • When cultured long enough to enable the generation of astrocytes, trisomy 21 induced pluripotent stem cells generate more astrocytes than control induced pluripotent stem cells, concomitant with a reduction in the generation of neurons.

    “Similarly, when cultured for long enough to enable the generation of astrocytes, T21 iPSCs generate more of this cell type than control iPSCs, concomitant with a reduction in the generation of neurons79,82,96,103.”
  • Trisomic iPSCs show significant increase in astrocyte differentiation.

    “A significant increase in astrocytes differentiated from trisomic iPSCs has been reported many times (Briggs et al., 2013; Chen et al., 2014; Hibaoui et al., 2014; Real et al., 2018; Mollo et al., 2021).”

  • Two other studies found decreased number of neurons from trisomic iPSCs.

    “However, two other studies, one using a separate isogenic line and one using non-isogenic matched iPSCs found that the trisomic line produced a decreased number of neurons compared to the euploid control (Lu et al., 2013; Hibaoui 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.
