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.
