background: linoleic acid (la) is a polyunsaturated fatty acid present in high concentrations in follicular fluid, when added to maturation culture media, it affects oocyte competence.objective: in the present study, we investigated effect of linoleic acid supplementation on in vitro maturation, embryo development and apoptotic related gene expression in ovinematerials and methods: the experime...

By means of a tissue culture technique, cells from chick embryos were procured in a state which proved to be suitable for electron microscopy. The electron micrographs disclosed details of cell structure not revealed by other methods of examination.

background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...

AIM To analyse the effects of hypoxia-reoxygenation on the development of rat embryos during early stages of gestation in vitro. METHODS Whole embryo culture techniques were used to culture Wistar rat embryos under a range of gassing regimes, some of which included periods of mild hypoxia. After the termination of cultures, embryos were morphologically examined and assessed, and their protein...

BACKGROUND The majority of research aimed at improving embryo development in vitro has focused on manipulation of the chemical environment, examining details such as energy substrate composition and impact of various growth factors or other supplements. In comparison, relatively little work has been done examining the physical requirements of preimplantation embryos and the role culture platfor...

human conjunctiva cell cultures. Following treatment with mithramycin, RNA synthesis was decreased by 85% in mouse embryo and BHK-21 cell cultures and by 45% in human conjunctiva cell cultures when compared to controls. The inhibition of RNA synthesis in BHK-21 cells was dosedependent and encompassed all cellular types of RNA. Although mithramycin inhibited protein and DNA syntheses in BHK-21 c...
