| Popis: | Uptake of 14 C-labelled α-amino isobutyric acid and a mixture of naturally occurring amino acids by normal mouse preimplantation blastocysts was found to be twice that of delayed implantation blastocysts. With both groups of embryos concentration of the amino acids against a gradient occurred. The results may explain, in part, the lower amino acid incorporation rates found with diapausing vs. normal blastocysts and open the question of “metabolic dormancy” of the diapausing embryo. |
