Embryo development: Some cells are more equal than others even at four-cell stage. ScienceDaily. Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2016 / 03 / 160324142932.htm.

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.

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells ...

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 ...

Stem cell biologist Jacob Hanna, a 2024 STATUS List member, says embryo models can be handled ethically, and can lead to advances in organ transplantation.

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, ...

The time immediately after the sperm and egg unite - the so-called zygote stage - seemed to be an extremely critical phase for the embryo's development. We wanted to find out why this is the case." ...

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 ...

In some new research featuring wondrous video of the cricket embryo — showing certain “right parts” (the cell nuclei) moving in three dimensions — Dr. Extavour, Dr. Donoughe and their ...
