Generation of Quarter- and Hemi-embryos via blastomere isolation reduces mosaicism and reveals editing patterns in Cas9 RNP-edited bovine embryos
Mosaicism is a persistent limitation in CRISPR/Cas9-based genome editing of preimplantation embryos. This study tested whether isolating blastomeres at the 2- or 4-cell stage reduces mosaicism in the resulting blastocysts and used the resulting variant patterns at the target region to analyze the duration of activity o...
