One-step versus two-step culture of mouse preimplantation embryos.

BACKGROUND A comparison has been made of the development of mouse zygotes in either one-step or two-step culture systems. METHODS Embryo culture, blastocyst cell counts and embryo transfer were done. RESULTS No significant differences were observed in the proportions of blastocysts, rates of hatching, numbers of cells in the inner cell mass (ICM) and trophectoderm (TE) that developed in pro...

Development of one-cell porcine embryos in two culture systems.

The effect of culture system and protein supplementation on the development of one-cell porcine embryos was investigated. One hundred and sixty-four one-cell embryos were collected at slaughter from 19 handmated gifts. Culture systems evaluated were microdrops of Whitten's medium (WM) under paraffin oil (M) or tubes with 4.0 ml of WM (T). Also tested was T with a 2.0 ml paraffin oil overlay (O)...

Human placental trophoblast culture: one-sided and two-sided models.

The investigation of human placental nutrient transfer and hormonal secretion presents a particular challenge because these processes depend on the intactness and orientation of the unicellular epithelial sheet of villous syncytiotrophoblast that mediates them. The isolated perfused placental cotyledon retains the architecture of the villi and has been very useful, but the presence of the non-t...
