Príklady embryo

• This testa probably reduced the rate of water loss and protected the embryo from physical injury.

• It appears that endogenous and/or exogenous serotonin in preimplantation embryos could be involved in complex autocrine/paracrine regulations of embryo development and embryo-maternal interactions.

• In addition, we recovered other embryos after storage of up to 18 months in liquid nitrogen to provide information on mutation during storage.

• Moreover, cold temperatures are required to overcome the physiological block present in the embryos of seeds when freshly ripe.

• This shows that willingness to do everything possible to help the embryo survive is not sufficient to exculpate the agents from the charge of instrumentalization.

• Percentages of live term fetuses were determined based on the number of 2-cell embryos transferred.

• Fused couplets were continued to the second activation 1.5 h after fusion, and then transferred to embryo culture medium to evaluate in vitro developmental ability.

• Nuclear reprogramming is characterized by functional modification of the transferred nucleus to direct normal embryo development.

• About 20 2-cell embryos were transferred into the oviduct of each pseudopregnant mouse.

• In all cases, two embryos could be transferred into the uterus.

• On day 5 of culture, embryos were transferred to drops of fresh media.

• The embryos did not reach the blastocyst stage, unlike the control groups.

• Another interesting finding is that male embryos, unlike female embryos, suffer when exposed to the time-lapse environment.

• The remaining embryos in each group that developed to the blastocyst stage were cryopreserved to evaluate cryotolerance and viability.

• Yet a reduction division must precede fertilisation or problems with ploidy will compromise the viability of the resulting embryo.
