Contrary to long-standing assumptions, human egg cells stay pristine for decades not by ramping up waste disposal, but by ...

New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits ‘reset’ so that the newly formed embryo can develop according to its own genetic program. The study was ...

Scientists combined 120 of these cells in a precise ratio, mixed them in a shaker, and then watched to see what developed — and soon, an embryo-like structure formed spontaneously.

In work published in December 2020 in the journal PLoS Biology, the team showed that this histone, a short variant normally found only in the developing sperm and egg cells of placental mammals, ...

In two back-to-back publications in the journal Cell Stem Cell, researchers from the groups of Vikas Trivedi at EMBL Barcelona and Jesse Veenvliet at the MPI-CBG have used gastruloids and trunk-like ...

Our stem-cell-derived human embryo model offers an ethical and accessible way of peering into this box. It closely mimics the development of a real human embryo, particularly the emergence of its ...

At the start of the process of egg-cell development, a "mother cell" in the ovule divides several times, in a sequence involving both meiosis and mitotic divisions. These divisions result in the ...
