Uncommon Encounter in Urachus: A Rare Case of Xanthogranulomatous Urachitis With Review of Literature [PDF]
Clinical Case ReportsUrachus is a fibrous remnant from embryologic development derived from the allantois, which is involved in waste elimination in the fetus. Typically, it extends from the dome of the bladder to the umbilicus.

Origin and flow-mediated remodeling of the murine and human extraembryonic circulation systems [PDF]
Frontiers in PhysiologyThe transduction of mechanical stimuli produced by blood flow is an important regulator of vascular development. The vitelline and umbilico-placental circulations are extraembryonic vascular systems that are required for proper embryonic development in ...

SLC20a1/PiT-1 is required for chorioallantoic placental morphogenesis
Vascular Biology, 2023 The placenta mediates the transport of nutrients, such as inorganic phosphate (Pi), between the maternal and fetal circulatory systems. The placenta itself also requires high levels of nutrient uptake as it develops to provide critical support for fetal ...
