Left-right asymmetric rotation of the Drosophila hindgut is driven by "cell sliding," a novel cellular behavior induced by chiral cell deformation, in which cells change their position relative to subjacent neighbors as sliding directionally.
Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.
Transcription factors downstream of Hippo signaling control formation of the Left-Right Organizer by regulating major signaling pathways, expression of transcription factors and regulators of epigenetic programming involved in this process.
A discovery of two previously unknown, molecularly distinct fields of cardiac progenitors in zebrafish provides evidence for cardiac laterality prior to the emergence of cardiac septation and allows novel insights into cardiac development and disease.
Publication bias, in which positive results are preferentially reported by authors and published by journals, can restrict the visibility of evidence against false claims and allow such claims to be canonized inappropriately as facts.
