Angiogenesis in tissue engineering : Breathing life into constructed tissue substitutes [PDF]

open access: yes, 2006
Long-term function of three-dimensional (3D) tissue constructs depends on adequate vascularization after implantation. Accordingly, research in tissue engineering has focused on the analysis of angiogenesis.

Vesicourachal Diverticulum: A Rare Entity [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
The urachus is a tubular embryonic structure connecting the allantois at the umbilicus to the bladder during development of foetus. It gets obliterated at 12th week of gestation and remains as a fibrous cord like structure extending from the umbilicus to

Primary immature teratoma of the liver in an adult: Case report

open access: yesRadiology Case Reports, 2023
Teratoma is an uncommon germ cell tumor and develops from at least 2 of the 3 germ cell layers: ectoderm, mesoderm, and endoderm. The origin of teratoma is primordial germ cells that migrate from the allantois to the gonadal ridges during embryogenesis ...

A Rare Case of Allantoic Cyst with Patent Urachus in Fetus with a Microdeletion in 1q21.1q21.2 Region

open access: yesDiagnostics, 2021
An allantoic cyst is a rare malformation with a frequency of 3 in 1,000,000 that may be seen antenatally by ultrasound assessment when the connection between the cloaca (future bladder) and the allantois fails to regress.

Hematopoietic potential of the pre-fusion allantois

open access: yesDevelopmental Biology, 2007
We previously showed that the fetal component of the placenta has a vigorous hematopoietic activity. Whether this organ is an environmental niche where hematopoietic stem cells (HSC) proliferate and become committed to various lineages, or whether it is also a site for HSC emergence, was left open.

Study of the Murine Allantois by Allantoic Explants

open access: yesDevelopmental Biology, 2001
The murine allantois will become the umbilical artery and vein of the chorioallantoic placenta. In previous studies, growth and differentiation of the allantois had been elucidated in whole embryos. In this study, the extent to which explanted allantoises grow and differentiate outside of the conceptus was investigated.
