Finally, the expression of apoptotic factor (cleaved caspase-3) and the index of apoptotic cells were investigated in bovine blastocysts
after treatment with P amurense and H.

Single and double blastocysts
transfers at day 5 also had statistically similar pregnancy (43.
Patients aged 41-42 years should receive single blastocyst
transfer if euploid embryos are available, or no more than four cleavage-stage embryos or three blastocysts
Influence of group embryo culture strategies on the blastocyst
development and pregnancy outcome.
he other two types of stem cell in the blastocyst
are the extra-embryonic trophoblast stem cells (TSCs), which will form the placenta; and primitive endoderm stem cells that will form the so-called yolk sac, ensuring that the fetus's organs develop properly and providing essential nutrients.
Morulae and blastocysts
yield were evaluated, respectively, on the sixth and seventh day after IVF.
Moreover, the blastocyst
rate was highest in injection 560 ng/uL Npm group and was lowest in injection 100 ng/uL PGA group.
Some authors are of the opinion that the embryos which are of good quality at the stage of cleavage should be transferred on day 3, otherwise they will not survive prolonged culturing to the stage of blastocysts
All remaining data, including fertilization and monospermic penetration rates, IVF efficiency and blastocysts
total cell number were analyzed by ANOVA and compared through the Tukey test.
Although the blastocyst
stage of human embryos has been extensively studied and documented, what happens beyond the seventh day of fertilization - when the embryo must implant itself into the uterus to survive - still remains shrouded in mystery.
Embryos were withdrawn at 96 hpi to collect blastocysts
according to our previous experiment .
