Developmental potency of the murine allantois
Development (Cambridge), 1997ABSTRACT The murine allantois is the future umbilical component of the placenta. The base of the allantois is also thought to contain the future germ line. We have examined the fate and developmental potency of cells within the murine allantois during gastrulation.

, 2008 Production of Influenza A Virus in the Cells of the Allantois
The Journal of Immunology, 1953Abstract The first cycle of influenza virus multiplication in the allantois may broadly be divided into three phases—the uptake of inoculated virus by the cells, the multiplication of this virus within the cells, and finally the liberation of newly-formed virus into the allantoic fluid.

Growth in the pre-fusion murine allantois
Anatomy and Embryology, 2000Prior to fusion with the chorion, the extraembryonic mesoderm of the murine (Mus musculus) allantois differentiates with distal-to-proximal polarity into at least two cell lineages: a chorio-adhesive cell lineage called mesothelium, and the endothelium of the umbilical vasculature.

The avian allantois: A depot for stress-released catecholamines
General and Comparative Endocrinology, 1992Plasma and amniotic and allantoic fluid of 10- and 14-day-old chicken embryos contain free dopamine (DA), norepinephrine (NE), and epinephrine (E). Compared with postnatal chickens, concentrations of DA and E in the plasma are very high, and they are even higher in the allantoic fluid.

Allantois as the bursa-equivalent in man
Medical Hypotheses, 1990This article proposes the hypothesis that allantois is the anatomical homologue of bursa of Fabricius in mammalia. This hypothesis is based on immunohistochemical study of sections from hematopoietic organs of three fetuses with cloacal exstrophy. In the complex maldevelopment of cloacal exstrophy the common features are absence of distal midgut and ...

Developing allantois is a primary site of 2′-deoxycoformycin toxicity
Teratology, 1996In this study, an assessment of normal mouse allantoic development and its sensitivity to 2'-(R)-deoxycoformycin (dCF; Pentostatin) exposure were examined. Both dissecting microscopy and scanning electron microscopy were used to describe the normal growth and morphogenesis of the mouse allantois over gestational days 7-10 as a preliminary step in ...

The mechanism of natural resistance of the allantois to influenza infection
Virology, 1959Abstract Eggs differ in their susceptibility to infection by influenza virus. This paper reports an investigation of the causes of this variation in suspended fragments of allantois-on-shell. The total yield of virus from an allantoic membrane is unrelated to the susceptibility of the membrane to infection by small inocula.

Treatment of a Case of Bovine Hydrops Allantois with Cloprostenol
British Veterinary Journal, 1981SUMMARY A four-year-old Ayrshire cow with hydrallantois was treated with cloprostenol at approximately six months of gestation. The pregnancy was successfully terminated with no post-parturient complications apart from retention of the placenta. Subsequent insemination resulted in the birth of a normal, healthy heifer calf.
