Embryonic development and fetal growth
Animal Reproduction Science, 1992Abstract Embryos and fetuses of domestic animals grow and develop at a very orderly rats. At the beginning cell numbers increase followed by differentiation and finally development of organs and systems. Although the rate of development and growth are orderly, they can be influenced by a number of factors.

Embryonic Stem Cells and Fetal Development Models
2016Pluripotent stem cells possess the unique capacity to proliferate indefinitely in culture and to differentiate into cells of the three germ layers, the endoderm, ectoderm and mesoderm. These important features render pluripotent stem cells ideal for both, basic studies in developmental biology and biomedical research in farm animals.

Embryonic and Fetal Development of the Mule Deer
The Journal of Wildlife Management, 1959The Rocky Mountain mule deer (Odocoileus h. hemionus) is one of the important species of big-game animals in the western mountain states. The mule deer, like other big-game species, has been subject to an increasing amount of hunting pressure. A knowledge of the breeding habits and reproductive pattern is necessary if gamemanagement agencies are to ...

Phenolsulphotransferase: localization in kidney during human embryonic and fetal development
The Histochemical Journal, 1994The aim of our study was to localize phenolsulphotransferase (PST) in the developing mesonephric and metanephric kidneys of the human embryo and fetus using immunohistochemical methods with an antibody preparation recognizing members of the human phenolsulphotransferase enzyme family.

Embryonic and fetal development in a commercial dam-line genotype
Animal Reproduction Science, 2005During depopulation of a breeding unit within Swine Graphics Enterprises, extensive data were collected and used to examine relationships among ovulation rate, the pattern of prenatal loss, and placental and fetal development. Groups of Large White x Landrace females (n=447) were slaughtered between day 20-30, 50-55 or 85-90 of gestation, with ...

Embryonic and Fetal Development
1974Many clinical studies have established the potential value of certain prostaglandins for the termination of pregnancy at all stages of gestation and for the induction of labor (Anderson and Speroff, 1973). Undoubtedly, the surge of interest in the clinical application of prostaglandins as therapeutic and antifertility agents will continue.

Effects of organolead compounds on rat embryonic and fetal development
Toxicology and Applied Pharmacology, 1972Abstract Tetraethyl lead (TEL) and tetramethyl lead (TML) and trimethyl lead chloride (TriML), were found to be essentially nonteratogenic in Sprague-Dawley rats. Oral doses of TEL (7.5, 15, or 30 mg/kg), TML (40, 80, 112, or 160 mg/kg) and TriML (15, 30, or 38 mg/kg) were administered as 3 divided doses during early organogenesis (days 9, 10, and 11)
