Interaction of human embryonic stem cells (hESC) with human amniotic epithelial cells (hAEC) confers hESC a pluripotent potential that resembles the anteriorized epiblast, which is predisposed to form the neural ectoderm.

Fog signaling with a narrow morphogenetic role in Drosophila has a deeply conserved function in epithelial morphogenesis across insects.

Late morphogenesis of the insect extraembryonic epithelia involves transient formation of a basal-basal bilayer to coordinate the functional contributions of two discrete tissues.

Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

Extraembryonic tissue spreading in the scuttle fly Megaselia abdita requires mechanical decoupling from the underlying yolk sac.

Loss of the transcription factor Rreb1 results perturbs epithelial architecture during mouse development resulting in invasive cell behaviors, severe cardiovascular defects, and embryonic lethality.

Embryonic fate-mapping approaches in zebrafish, Xenopus and lamprey illuminate the evolutionary origins of carotid body glomus cells and pulmonary neuroendocrine cells.

The chloride channel Ano1/Tmem16a plays an essential and non-redundant role in the developing airway by inhibiting mucus cell hyperplasia and promoting proper immune function of the airway mucosal barrier.

Telophase reorientation corrects errors in spindle orientation that persist after imprecise initial spindle positioning during early mitosis, and contributes to balancing self-renewal with differentiation during epidermal development.

Analyses of transcriptomic dynamics in a new model of human amnion formation identify five continuous amniogenic transcriptional phases as well as a critical role of TFAP2A in amnion fate progression.
