The requirement for WNT signaling in mesendoderm differentiation is temporally separate from that of ACTIVIN signaling and acts to switch the output of ACTIVIN/SMAD2 from pluripotency maintenance to mesendoderm patterning.
A bioengineering approach identifies tissue morphology as an effective variable for controlling the inception of neural organoid morphogenesis via induction of a biomimetic, singular neural rosette tissue cytoarchitecture.
A generally applicable two-hybrid assay demonstrates that MHC class I heavy chains devoid of beta-2 microglobulin associate within and across allotypes, with implications for endocytosis and autoimmunity.
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.
Axonal arborisation growth is regulated by dynamic, focal localisations of Neurexin and Neuroligin that provide stability for filopodia, enabling a 'stick and grow'-based mechanism, wholly independent of synapse formation.
