Yolk sac tumors of the ovary [PDF]
Cancer, 1970 Eighteen instances of ovarian tumor with microscopic pattern similar to that of the testicular tumors which we termed yolk sac or vitelline are presented. In the ovary, though not in the testis, this pattern has often been called “Schiller mesonephroma.” Reasons are given for our preference for the term yolk sac tumor to that of mesonephroma for these ...

Deficiency of autotaxin/lysophospholipase D results in head cavity formation in mouse embryos through the LPA receptor-Rho-ROCK pathway [PDF]
, 2010 Autotaxin, encoded by the Enpp2 gene, generates lysophosphatidic acid (LPA) extracellularly, eliciting various cellular responses through specific LPA receptors.

Bacterial Contamination in the Components of the Chickens' Eggs
The Iraqi Journal of Veterinary Medicine, 2020 In 120 hen eggs ( local eggs , hatching eggs and table eggs ) a bacteriological pollution with high rate was observed by isolating 427 bacterial isolates from which 199 isolates related to the egg's shell , 117 isolates related to albumen sac, and 111 ...

Haemogenic endocardium contributes to transient definitive haematopoiesis. [PDF]
, 2013 Haematopoietic cells arise from spatiotemporally restricted domains in the developing embryo. Although studies of non-mammalian animal and in vitro embryonic stem cell models suggest a close relationship among cardiac, endocardial and haematopoietic ...

Yolk sac tumors of the testis [PDF]
Cancer, 1970 The discovery of 2 yolk sac carcinomas of the mouse has established a basis in comparative pathology for the occurrence of this type of tumor in other species with yolk sacs. Grafts and tissue cultures of extra-embryonic yolk sac of the mouse have developed a clear understanding of the types of tissues one might expect in yolk sac carcinomas.

The mammalian yolk sac placenta [PDF]
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2008 AbstractThere are three fetal membranes in mammals, namely the yolk sac, allantois and amnion, but only the first two form a placenta. In Monotremata (monotremes), Marsupialia (marsupials) and Placentalia (eutherians), the yolk sac transfers nutrients originating from uterine glandular secretion or the maternal blood.
