by the eight-cell stage, but its exact timing and profile are unclear. To address this, we
profiled gene expression at depth in human metaphase II oocytes and bipronuclear (2PN)
one-cell embryos. High-resolution single-cell RNA sequencing revealed previously
inaccessible oocyte-to-embryo gene expression changes. This confirmed transcript
depletion following fertilization (maternal RNA degradation) but also uncovered low …
