Aggregate formation and developmental potentials of aggregates with various embryo numbers using the empty zona method.

† In the experiment of total cell number, the aggregated morula with the dissociated blastomeres (3 or 4) were downcounted as less as 1X (as represented in Fig 4; 5X and 8X were counted as 4X and 7X, respectively)1X group is the denuded 4-cell stage embryos that were individually injected into the empty zona‡ the mean value is the proportions of embryo that became morulaeWithin the same column, values with different asterisks are significantly different (* p Aggregate formation and developmental potentials of aggregates with various embryo numbers using the empty zona method.
