Vitrification of isolated human blastomeres.
This article describes a new methodology for preserving and banking isolated human blastomeres, whose originality is based on packing the blastomere into an emptied zona pellucida before vitrification. After warming, 75.7% of blastomeres survived and developed at a rate comparable to that in noncryopreserved blastomeres (62.5% cleavage, 26.6% compaction, and 20.3% cavitation).
