Loss of Tbx4 blocks hindlimb development and affects vascularization and fusion of the allantois

Naiche, L. A., Papaioannou, Virginia E.·2003·Development

Abstract

Tbx4 is a member of the T-box family of transcription factor genes, which have been shown to play important roles in development. We have ablated Tbx4 function using targeted mutagenesis in the mouse. Embryos homozygous for the null allele fail to undergo chorioallantoic fusion and die by 10.5 days post coitus. The allantoises of Tbx4-mutant embryos are stunted, apoptotic and display abnormal differentiation. Endothelial cells within mutant allantoises do not undergo vascular remodeling. Heterozygous embryos show a mild, transient growth defect in the allantois. Induction of a hindlimb field occurs normally in Tbx4mutants and initial patterning of the hindlimb bud appears normal. However,hindlimb buds from Tbx4 mutants fail to develop either in vivo or in vitro and do not maintain Fgf10 expression in the mesenchyme. The expression of another, closely-linked, T-box gene, Tbx2, is reduced in both the hindlimb and the allantois of Tbx4-mutant embryos prior to the development of overt morphological abnormalities, which suggests that Tbx4 regulates Tbx2 in these tissues.

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.
