Preimplantation

The preimplantation embryo passes through distinct metabolic phases, undergoing changes in protein synthesis, energy requirements and amino acid uptake as it develops from a fertilized zygote to the blastocyst stage. Concurrently, it also undergoes morphological changes, particularly at compaction when the first differentiative process is observed.
