In the third embryo cell cycle (ECC3), the 4-cell embryo duplicates all blastomeres and an 8-cell
embryo can be observed on day 3 of cultivation.
Compared with the PBS and blank control groups, the percentages of 6- to 8-cell
stage embryos on the third day, as well as blastula and morula stage embryos on the fifth day, were significantly lower in the antibody group.
Our results showed that [H.sub.2][O.sub.2] treatment did not significantly reduce the rates of 2-cell formation, 4-cell formation, or 8-cell
formation (P > 0.05) but produced a significant decrease in the rates of blastocyst formation (P < 0.05) (Figure 1), which was similar to phenomena observed in the clinic [29, 30].
The energetic metabolism between the zygote and the 8-cell
stage depends on pyruvate, glucose and oxygen, with relatively little consumption of these (14,15) (Figure 2).

In the 8-cell
plastic trays, 4 cells contained leaf tissue and 4 cells contained stem tissues (1 cell for each insecticide rate).
Following fertilization, embryo divides from 2- to 4-cell stages and subsequently 8-cell
stage, in which the latter formed a morula which then develops into blastocyst that hatches upon entering the uterine cavity .

In these species, mesoderm and endoderm are formed from descendants of the four vegetal blastomeres at the 8-cell
stage, with the ectoderm/endoderm boundary below the third cleavage plane at the equator of the embryo (Fig.

embryos generated from gamma-irradiated male mice in the absence and presence of Vitamine E.Int J Radiat Biol., 82(11): 817-22.
Accurate temperature control needed for some enzyme kinetic measurements in food such as citric acid, glucose and saccharose in foods can be achieved using a peltier temperature controlled 8-cell
A standard 8-cell
battery allows consumers to use it for up to 10.5 hours between charges; enough for a long flight or an entire day of working on the road.
