1. The Effects of Different Eggshell Temperatures Between Embryonic Day 10 and 18 on Broiler Performance and Susceptibility to Ascites
ABSTRACTThe aim of the current study was to determine the effects of low (33.3-36.7 ˚C), control (37.8-38.2 ˚C) and high (38.9-40.0 ˚C) eggshell temperatures (ESTs) between days 10-18 of incubation on broiler performance and susceptibility to ascites. The effects of different ESTs on hatchling weight were significant. The highest residual yolk sac weight

2. Caracterização de células tronco mesenquimais oriundas de líquido amniótico, líquido alantóide e conteúdo vitelino de fetos caninos / Characterization to mesenchymal stem cells from amnioitc fluid, alantois fluid and yolk sac fluid from canine foetus
O cão é um excelente modelo pré-clínico para o estudo de doenças, testes farmacológicos e novas terapias para futura aplicação em humanos. Desta forma, estudamos o modelo canino como fonte de células tronco de anexos fetais, o líquido amniótico, alantóide e conteúdo vitelino. Uma vez que hoje, as células tronco apresentam uma esperança na cura

3. The giant yolk sac: a model for studying early placental transport.
Nine and a half day rat embryos can be cultured for 48 hours in whole heat-inactivated rat serum using the roller culture method described by New, Coppola & Terry (1973). We have prolonged the culture period, usually by seven days. Although the embryo dies almost immediately during this extended culture period, the yolk sac continues to grow and reaches a di

4. Sites of Serum α-Fetoprotein Synthesis in the Human and in the Rat*
Selected tissues from human embryos of 6 to 9 weeks' gestation, from rat fetuses of 15 days' gestation, and from rats 2 days of age were incubated with 14C-labeled amino acids. Immunoelectrophoresis of the culture fluid after incubation, using rabbit antisera against human and rat fetal serum proteins, followed by radioautography revealed that: 1) Radioactiv

5. Adult hemoglobins are synthesized in erythroid colonies in vitro derived from murine circulating hemopoietic progenitor cells during embryonic development.
Circulating peripheral blood cells and disaggregated yolk sac cells were obtained from normal mouse embryos as early as day 9 of gestation, prior to the formation of the fetal liver. These were cultured in vitro in plasma clots or methylcellulose, in the presence of either embryonic fluid or adult spleen cell-conditioned medium, with or without added erythro

6. Apolipoprotein J expression at fluid-tissue interfaces: potential role in barrier cytoprotection.
Apolipoprotein J (apoJ) is a sulfated secreted glycoprotein that exhibits ubiquitous expression, evolutionary conservation, and diverse tissue inducibility. It has been proposed to have roles in programmed cell death, sperm maturation, complement regulation, and lipid transport. To identify cell types that synthesize apoJ and to aid evaluation of its functio

7. Alpha-feto-protein during development and in disease.
An alpha-feto-protein (AFP) is present in many mammals, in birds, and in sharks during development. The AFP present in different species have similar physicochemical properties and often have common antigenic determinants. Their study, both in health and disease, has provided a useful model for the understanding of other phase-specific antigens and the activ
