library_construction_protocol: Single-cell isolation: Collection of single blastomeres was performed using micromanipulation. Embryos were transferred into M2 medium supplemented with 5 μg/ml cytochalasin B (Sigma-Aldrich) for 10 min. Then, the zona pellucida was cut by the LYKOS laser system (Hamilton Thorne) in a micromanipulation chamber, which was put on a warmed stage (37°C) in an inverted microscope (Olympus Co.). After cutting the zona pellucida, a fire-polished injection pipette (inner dia. 30 µm) was inserted through the hole of the zona pellucida, single blastomere was isolated. After the single-cell isolation, sample preparations were performed as described (Miura et al., 2020). DNA samples were subject to whole-genome amplification (WGA) with a SeqPlex kit (Sigma, SEQXE). NGS libraries were constructed WGA DNA with an NGS LTP Library Preparation Kit (KAPA, KK8232) according to the manufacturer's instructions
