(A–C) Fresh blastomere used as control: (A) global view (scale: 10 μm), (B) detail of plasma membrane integrity and cytoplasm, and (C) nuclear and chromatin detail. (D–F) Degenerated blastomere used as control: (D) global view (scale: 10 μm), (E) detail of plasma membrane integrity and cytoplasm, and (F) nuclear and chromatin detail. (G–I) Blastomere vitrified and warmed with Cryotip method: (G) global view (scale: 10 μm), (H) detail of plasma membrane integrity and cytoplasm, and (I) nuclear and chromatin detail. (J–L) Blastomere vitrified and warmed with Cryotop method: (J) global view (scale: 10 μm), (K) detail of plasma membrane integrity and cytoplasm, and (L) nuclear and chromatin detail. Scale of details: 2 μm.
