Defective neuronogenesis in the absence of Dlx5

Abstract

Dlx genes play an important role in the control of the development of the central nervous system (CNS). Single or compound inactivation of Dlx1, Dlx2, or Dlx5 in the mouse causes defects of neuronal migration and differentiation. Dlx5, in particular, is essential for the correct development of the olfactory system. Targeted inactivation of Dlx1 and Dlx2 in the mouse results in abnormal neuronal differentiation in the embryonic subcortical forebrain and is associated to the loss of Dlx5 and Dlx6 expression. So far, however, it has been impossible to investigate the role of Dlx genes on late neurogenesis, as their inactivation leads to perinatal death. We have now generated cultures of neural stem cells (NSCs) derived from embryonic and newborn Dlx5-null mice, and we have compared their capacity to differentiate in vitro to that of equivalent cells derived from normal littermates. We show here that in the absence of Dlx5, NSCs derived from newborn animals have a severely reduced capacity to generate neurons. This is not the case for cells derived from E12.5 embryos. Forced expression of Dlx5 in cultures of newborn mutant NSCs fully restores their neuronogenic potential. Our data suggest that Dlx5 is essential for secondary (postnatal) neuronogenesis.

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.
