Changes in the Prevalence of Embryologic Remnants in Umbilical Cord With Gestational Age.

Grottling E, Gisselsson D.
Pediatric and developmental pathology : the official journal of the Society for Pediatric Pathology and the Paediatric Pathology Society. 2018 Dec;()1093526618813663.
The aim of this study was to examine the prevalence of embryologic remnants in umbilical cords of different gestational ages. Sections from 392 umbilical cords were examined using light microscopy. Of these, 52% contained at least 1 remnant, most commonly of the allantoic duct type. Although there w

Umbilical cord anomalies: antenatal ultrasound findings and postnatal correlation.

Kong CKY, Zi Xean K, Li FX, Chandran S.
BMJ case reports. 2018 Oct;2018().
Umbilical cord anomalies are rare. The differential diagnosis for a cystic structure around the umbilical cord and its insertion include pseudocyst, omphalomesenteric duct cyst, haemangioma, omphalocele or anterior abdominal wall defects. Although cord anomalies can be detected through antenatal ult

during gestation, the urachus represents the connection between the dome of the bladder and the allantoic duct. This infection occurs preferentially in young adults, advocating the haematogenous or lymphatic pathway as possible routes of transmission, while a cord or bladder origin may also occur. U

Cytokeratin Expression in the Stomach Epithelia of the Chicken Embryo is Regulated by Epithelial-Mesenchymal Interactions

… In the proventriculus, antigens detected by monoclonal antibodies (PKK1 and AE3) against cytokeratins invariably decreased in gland cells which synthesize pepsinogen, while luminal and duct epithelial cells were positive to these antibodies. … Under the same experimental conditions, the small-intestinal and allantoic epithelia also formed complex glands but did not express pepsinogen, and PKK1 and AE3 antigens were actively expressed throughout the epithelia. …
